13. Pointer and 2D arrayGem WeBlog

A two dimensional array can be accessed using two subscripts, with the first representing the row number and the second representing the column number. Elements are stored in memory row by row. A 2D array can be viewed as a collection of 1D arrays, with each row representing an array of the second dimension size. The base address of the 2D array points to the first element at index [0][0], and any element can be accessed using the generalized form of base_pointer[i][j].

Data typesSyed Umair

This document assigns a group project on data types in C++ to seven students. It discusses the three main data types in C++ - character, integer, and float. Character data can store single characters, integer data stores whole numbers, and float data stores numeric values with decimals. It also covers variable declaration and initialization in C++, noting that variables must be declared before use and can be initialized with a value upon declaration. The document assigns different aspects of the data types topic to the seven students listed at the top for further explanation in the project.

Pointers in CMonishkanungo

The document discusses pointers in C programming. It defines pointers as variables that store memory addresses and can point to data of various types, such as integers, characters, arrays, functions, and other pointers. It explains how to declare pointers, dereference pointers to access data, use pointers as function arguments, perform arithmetic on pointers, and use pointers to structures. Pointers allow accessing data indirectly through memory addresses, provide flexibility in passing arguments to functions, and are fundamental to working with arrays and structures in C.

Introduction To PythonVanessa Rene

Python is an interpreted programming language created by Guido van Rossum in 1991. It has an elegant syntax, large standard library, and is used widely for data science, machine learning, web development, and more. Key Python libraries for data analysis include NumPy, pandas, and matplotlib. Pandas allows importing and cleaning data from files like CSVs, and matplotlib can be used to visualize and present analyzed data. For example, a program can use pandas to read baby name data from a CSV, find the most popular name with the highest birth count, and plot the results to clearly present the findings.

User Defined FunctionsPraveen M Jigajinni

The document discusses user-defined functions in C++. It explains that a function allows structuring programs in a modular way by grouping statements that are executed when the function is called. The format of a function includes its return type, name, parameters, and function body enclosed in curly braces. Functions can be called by passing arguments, which are copied to the function's local parameter variables. Functions can return a single value. Function prototypes declare a function's interface without defining its body, allowing a function to be called before it is defined. Arguments can be passed by value, where copies are passed, or by reference, where the function can modify the original variables. Arrays can be passed to functions by only passing the array name

Python DictionarySoba Arjun

A dictionary in Python is an unordered collection of key-value pairs where keys must be unique and immutable. It allows storing and accessing data values using keys. Keys can be of any immutable data type while values can be of any data type. Dictionaries can be created using curly braces {} or the dict() constructor and elements can be added, accessed, updated, or removed using keys. Common dictionary methods include copy(), clear(), pop(), get(), keys(), items(), and update().

The document provides details on the size and range of standard data types like short int, int, long, float, double etc. It also explains various type modifiers and derived data types.

Chapter 5 Stack and Queue.pdfGirT2

This document discusses stacks and queues. It begins by describing basic stack operations like push and pop and basic queue operations. It then discusses the implementation of stacks and queues, including using linked lists and arrays to represent stacks. Key aspects covered include stack errors like overflow and underflow, and functions for basic stack operations like push(), pop(), peek(), isEmpty(), and sizeOfStack(). It also discusses representing a stack using a linked list.

Python tuples and DictionaryAswini Dharmaraj

Tuples are immutable sequences like lists but cannot be modified after creation, making them useful for storing fixed data like dictionary keys; they are created using parentheses and accessed using indexes and slices like lists but elements cannot be added, removed, or reassigned. Dictionaries are mutable mappings of unique keys to values that provide fast lookup of values by key and can be used to represent polynomials by mapping powers to coefficients.

C++ Standard Template LibraryIlio Catallo

This set of slides introduces the reader to a subset of the C++ Standard Library called the Standard Template Library (STL). The STL provides a collection of parameterized containers and algorithms, and it is the most successful example of an approach to programming called generic programming. In this presentation, we aim at studying the ideals and concepts of the STL by re-implementing small parts of the library. Specifically, we first show how we can discover requirements on types in order to devise generic algorithms. Then, we focus on how to make algorithms independent of containers through the pivotal abstraction of iterators. To this end, we replicate the standard algorithm for finding the minimum in a sequence (min_element), which we subsequently match with a custom forward iterator over intrusive linked lists of integers. Finally, we see how function objects can be used to customize containers and algorithms alike. This allows us to deepen our understanding of ordering relations, and, in particular, to introduce the concept of strict weak orderings.

Variable scope in phpMUHAMMED MASHAHIL PUKKUNNUMMAL

This document discusses the different scopes of variables in PHP - local, global, and static. Local variables can only be accessed within their declared function. Global variables are accessible from any part of a script outside of functions. The global keyword allows access to global variables from within functions. Static variables retain their value between function calls, unlike local variables which are deleted after each call.

Looping Statements and Control Statements in PythonPriyankaC44

This document discusses looping statements and control statements in Python. It explains while loops, for loops, and the use of break, continue, else and pass statements. Some key points: - While loops repeatedly execute statements as long as a condition is true. For loops iterate over a sequence. - Break and continue statements can alter loop flow - break exits the entire loop, continue skips to the next iteration. - The else block in loops runs when the condition becomes false (while) or the sequence is complete (for). - Pass is a null operation used when syntax requires a statement but no operation is needed. Several examples of loops and control statements are provided to demonstrate their usage.

While loopRabiyaZhexembayeva

The document discusses while loops in programming. It defines a while loop as a structure that executes a sequence of instructions multiple times. It explains that while loops are used when the number of repetitions is unknown and cannot be calculated in advance. The document provides examples of using while loops with loop counters to run code a specific number of times and examples of infinite loops. It also discusses using the break statement to exit a loop early.
