7. Rest parameters | ES6 | JavaScript
Download as pptx, pdf0 likes168 views
The document discusses rest parameters in ES6, which allow a function to accept an indefinite number of arguments as an array. It explains that rest parameters must be the last part of a function's parameters and are prefixed with three dots. The document compares rest parameters to the arguments object, noting rest parameters can be iterated over like arrays but arguments cannot. It also demonstrates how rest parameters can be destructured to assign array elements to distinct variables in the function body.

C Pointers
C Pointersomukhtar Pointers in C allow variables to hold the memory addresses of other variables and data types. Pointers use the asterisk (*) and ampersand (&) operators - * accesses the value at a memory address, while & returns the memory address of a variable. Pointers are useful for passing arguments to functions, returning multiple values from functions, and accessing arrays through a single pointer variable. Pointer arithmetic increments or decrements a pointer by the size of its data type. Pointer-to-pointers allow pointers to hold the addresses of other pointer variables. Proper initialization and boundary checking is important to avoid crashes with pointers.
Chapter12 array-single-dimension
Chapter12 array-single-dimensionDeepak Singh An array is a collection of elements of the same data type. It can be initialized with values specified in braces when declared. Individual array elements can be accessed using the array name and subscript index. Arrays can be passed as parameters to functions by passing the array name without brackets. Basic operations on arrays include traversing, searching, sorting, and merging elements.
Regular expressions and php
Regular expressions and phpDavid Stockton The document discusses regular expressions (regex) in PHP. It begins with a brief introduction to regex, then provides examples of common PHP functions for using regex like preg_match(), preg_replace(), and preg_quote(). The document also shares a very long regex pattern that is intended to match all valid email addresses. It notes that accurately matching email addresses with a regex is challenging.
Array of pointer
Array of pointerfasalsial1fasalsial1 An array of pointers is an array where each element is a pointer that can store the memory address of other objects. For example, an integer array of pointers is declared and each pointer element is made to point to integer variables, taking their values as input and outputting them using the pointer array. Arithmetic operations like indirection, reference, assignment, incrementing, and decrementing can be used on pointers, while comparison is only valid between pointers pointing to the same array.

Array
ArrayHajar An array allows us to store multiple values of the same data type using a single variable name. It represents the data contiguously in memory. We declare an array by specifying its type, name and size. Individual elements can be accessed using indexes and assigned values. Arrays can be passed to functions along with their size.
Pointers in c++
Pointers in c++Vineeta Garg Pointer is a variable that stores the memory address of another variable. It allows dynamic memory allocation and access of memory locations. There are three ways to pass arguments to functions in C++ - pass by value, pass by reference, and pass by pointer. Pass by value copies the value, pass by reference copies the address, and pass by pointer passes the address of the argument. Pointers can also point to arrays or strings to access elements. Arrays of pointers can store multiple strings. References are alternative names for existing variables and any changes made using the reference affect the original variable. Functions can return pointers or references.

Lecture 8Mohammed Saleh The document discusses structures, arrays of structures, unions, enums, and pointers in C++.
The key points are:
1. Structures allow grouping of different data types together and can be passed as function arguments or returned as values. Structure members can be assigned via memberwise assignment.
2. Arrays of structures create arrays whose elements are structures. Each element can then be accessed like an individual structure.
3. Unions allow storing different data types in the same memory space but only one at a time. They are useful to save space for mixed data formats.
4. Enums create symbolic constants for integer values starting from 0 by default. They define a new data type.

Function in Python
Function in PythonYashdev Hada This document discusses Python functions. It defines a function as a reusable block of code that performs a specific task. Functions help break programs into smaller, modular chunks. The key components of a function definition are the def keyword, the function name, parameters in parentheses, and a colon. Functions can take different types of arguments, including positional, default, keyword, and variable length arguments. Objects like lists, dictionaries, and sets are mutable and can change, while numbers, strings, tuples are immutable and cannot change. The document provides examples of passing list, tuples, and dictionaries to functions using techniques like tuples, asterisk operators, and double asterisk operators.

Arrays in programming
Arrays in programmingTaseerRao The document provides an overview of arrays in Java, including:
- Arrays can hold multiple values of the same type, unlike primitive variables which can only hold one value.
- One-dimensional arrays use a single index, while multi-dimensional arrays use two or more indices.
- Elements in an array are accessed using their index number, starting from 0.
- The size of an array is set when it is declared and cannot be changed, but reference variables can point to different arrays.
- Common operations on arrays include initializing values, accessing elements, looping through elements, and copying arrays.
Functions in Python with all type of arguments
Functions in Python with all type of argumentsriazahamed37 Functions are the structured or procedural programming way of
organizing the logic in the programs.
Functions are often compared to procedures. Both are entities
which can be invoked, but the traditional function or "black box,"
perhaps taking some or no input parameters, performs some
amount of processing and concludes by sending back a return
value to the caller.
Some functions are Boolean in nature, returning a "yes" or "no"
answer, or, more appropriately, a non-zero or zero value.
Procedures, often compared to functions, are simply special cases,
functions which do not return a value.
Python procedures are implied functions because the interpreter
implicitly returns a default value of None.
Calling Functions
Functions are called using the same pair of parentheses that are
used to. In fact, some consider ( ( ) ) to be a two-character
operator, the function operator.
Any input parameters or arguments must be placed between these
calling parentheses.
Parentheses are also used as part of function declarations to define
those arguments.
The concept of keyword arguments applies only to function
invocation. The idea here is for the caller to identify the arguments
by parameter name in a function call. This specification
allows for arguments to be missing or out-of-order because the
interpreter is able to use the provided keywords to match values to
parameters.
Default arguments are those which are declared with default
values. Parameters which are not passed on a function call are
thus allowed and are assigned the default value.
Functions are created using the def statement. The header line consists of the def keyword, the function name,
and a set of arguments (if any).
The remainder of the def clause consists of an optional but
highly-recommended documentation string and the required
function body suite
Functions may return a value back to its caller and those which are
more procedural in nature do not explicitly return anything at all.
Languages which treat procedures as functions usually have a
special type or value name for functions that "return nothing.“
Like most languages, python also return only one value/object from
a function. One difference is that in returning a container type, it will
actually return more than a single object.
In Python, functions are just like any other object. They can be
referenced (accessed or aliased to other variables), passed as
arguments to functions, be elements of container objects like lists
and dictionaries, etc.
The one unique characteristic of functions which may set them
apart from other objects is that they are callable, i.e., can be
invoked via the function operator
A Python function's set of formal arguments consists of all
parameters passed to the function on invocation for which there is
an exact correspondence to those of the argument list in the
function declaration.
These arguments include all required arguments (passed to the
function in correct ordered

data structure, stack, stack data structure
data structure, stack, stack data structurepcnmtutorials The document discusses stacks, which are linear data structures that follow the LIFO (last in, first out) principle. Values are inserted into and retrieved from one end, called the top of the stack. The two main operations are push, which inserts a value into the stack, and pop, which retrieves a value. An example C program demonstrates these operations on a stack implemented with an array. The stack starts empty and grows as values are pushed on until it reaches its maximum size, at which point it is full. Values can be continuously popped off until the stack is empty again.
1.introduction to data_structures
1.introduction to data_structurespcnmtutorials This document discusses different types of data structures, including linear and non-linear structures. Linear structures like arrays, stacks, queues, and linked lists store data in a linear order. Stacks follow LIFO while queues follow FIFO. Non-linear structures like trees and graphs store data in a non-linear fashion. Trees have a root node, child nodes, and terminal nodes. Graphs are sets of nodes connected by edges that can form connected or non-connected graphs.

Amol Borkar, Product Marketing Director at Cadence, presents the “Solving Tomorrow’s AI Problems Today with Cadence’s Newest Processor” tutorial at the May 2025 Embedded Vision Summit.
Artificial Intelligence is rapidly integrating into every aspect of technology. While the neural processing unit (NPU) often receives the majority of the spotlight as the ultimate AI problem solver, it is essential to recognize that not all AI workloads can be efficiently executed on an NPU and that neural network architectures are evolving rapidly. To create efficient chips and systems with market longevity, designers must plan for diverse AI workloads that include networks yet to be invented.
In this presentation, Borkar introduces a new processor from Cadence Tensilica. This new solution is designed to complement any NPU, creating the perfect synergy between the two processing engines and establishing a robust AI subsystem able to efficiently support workloads yet to be encountered. This combination allows developers to achieve efficiency and performance on the AI workloads of today and tomorrow, paving the way for future innovations in AI-powered devices.

National Fuels Treatments Initiative: Building a Seamless Map of Hazardous Fu...Safe Software The National Fuels Treatments Initiative (NFT) is transforming wildfire mitigation by creating a standardized map of nationwide fuels treatment locations across all land ownerships in the United States. While existing state and federal systems capture this data in diverse formats, NFT bridges these gaps, delivering the first truly integrated national view. This dataset will be used to measure the implementation of the National Cohesive Wildland Strategy and demonstrate the positive impact of collective investments in hazardous fuels reduction nationwide. In Phase 1, we developed an ETL pipeline template in FME Form, leveraging a schema-agnostic workflow with dynamic feature handling intended for fast roll-out and light maintenance. This was key as the initiative scaled from a few to over fifty contributors nationwide. By directly pulling from agency data stores, oftentimes ArcGIS Feature Services, NFT preserves existing structures, minimizing preparation needs. External mapping tables ensure consistent attribute and domain alignment, while robust change detection processes keep data current and actionable. Now in Phase 2, we’re migrating pipelines to FME Flow to take advantage of advanced scheduling, monitoring dashboards, and automated notifications to streamline operations. Join us to explore how this initiative exemplifies the power of technology, blending FME, ArcGIS Online, and AWS to solve a national business problem with a scalable, automated solution.

7. Rest parameters | ES6 | JavaScript
- 1. Rest Params | ES6 JAGADEESH PATTA ( PJ )
- 2. Agenda Introduction to Rest Parameters Rest params vs arguments object. Destructuring rest params. Live Example
- 3. Introduction The rest parameters allows us to represent an indefinite number of arguments as an array. Rest params of a function prefixed with(…). The rest params index starts with 0 index. Rest params must be last param of function arguments.
- 4. Introduction Syntax function function_name(…restParams){ // function body } function_name( ) // function calling
- 5. Introduction Example function getEmployeeDetails(…rest){ return rest[0] + “ ”+ rest[1] + “ ” + rest[2]; } getEmployeeDetails( ‘emp01’, ‘PJ’, ‘SSE’ ) // function calling
- 6. Rest params vs arguments object Rest params is an instance of array. But arguments object is not an instance of array. We can apply sort, map, forEach operations on rest params But we can’t on arguments object. Arguments object has one feature is called callee property. But rest params doesn’t have it.
- 7. Destructuring Rest params Rest params can be Destructured, that means that their data can be unpacked into distinct variables. Syntax function function_name(…[params]){ // function body }
- 8. Destructuring Rest params Example function getSumOfNumbers(…[a, b, c]){ return a + b + c; } getSumOfNumbers( 10, 20, 30 );
- 9. Any Q ?
