- 6. Algorithms & Data Structure • An algorithm is nothing but a mention of steps to solve a problem. They are essentially a solution. • Efficient algorithm and data structure makes your code scalable. • Why big companies like Google, Facebook, and Amazon hire programmers who are exceptionally good at optimizing Algorithms.

- 28. Basics of Programming • Irrespective of the programming language you choose to learn, the basic concepts of programming are similar across languages. Some of these concepts include: • Variable Declaration • Basic Syntax • Data Type and Structures • Flow Control Structures (Conditionals and loops) • Functional Programming • Object-Oriented Programming • Debugging • IDEs and Coding Environments
- 29. Variables
- 30. Variable Declaration • Variables are containers for storing data values, a memory location for a data type. Variables are created using a declaration or keyword that varies across languages. • Variable names are usually alphanumeric, that is, they contain a-z and 0-9. They can also include special characters like underscore or the dollar sign. • Variables can hold values of any data type supported by the programming language. This value may change during program execution.
- 31. Syntax
- 32. Basic syntax • Every programming language has its syntax, and you must learn the fundamental syntax of the language you are learning. • Syntax refers to the set of rules that define the structure of a language. • It is almost impossible to read or understand a programming language without its syntax.
- 33. Example let us declare a variable named greet and assign the value “Hello World” to it:
- 34. C++
- 35. Java script
- 36. Java
- 37. Python
- 38. “Hello world” in different language.
- 39. Data Types
- 40. Data types • Data types refer to the classification of data. The most common data types include: • String • Boolean (true or false) • Numbers, which includes integers (whole numbers from 1) and floating- point numbers (decimal-base) • Characters (includes single alphabets or numbers) • Arrays (a collection of data, usually of the same data type)
- 41. Data Structure
- 42. Data Structure • A Data Structure is a collection of data values. • Data structures are important in computer programming for organizing, managing, and storing data quickly and efficiently. • Some common types of data structures include: • Stacks • Heaps • Trees • Linked lists • Queues • Arrays • Tables • Graphs

- 51. Flow of control
- 52. Flow control structures • Flow Control Structures are the fundamental components of computer programs. They are commands that allow a program to “decide” to take one direction or another. • Sequential • Selection • Iteration
- 53. Sequential • The most basic control flow is sequential control flow. It involves the execution of code statements one after the other. A real-world example is following a cooking recipe.
- 54. Selection (conditionals) • The basic premise of selection flow control is, the computer decides what action to perform based on the result of a test or condition equalling true or false.
- 55. Iteration (Loops). • A loop is a programming structure that allows a statement or block of code to be run repeatedly until a specified condition is no longer true (will return Boolean, true or false). It is one of the most powerful and fundamental programming concepts.
- 57. Functional programming • Functions are containers that take in a set of inputs and return an output. It is not required for a function to return a value. Pure functions will always give the same result for the same set of inputs. • Functional Programming is a straightforward method of building software that involves using pure functions. This method eliminates the occurrence of data mutation or side effects.
- 58. Object-oriented programming • Object-Oriented Programming (OOP)**is a programming concept that revolves around ‘objects’ and ‘methods’. • There are four principles of OOP: • Inheritance • Polymorphism • Abstraction • Encapsulation
- 59. Top Down/Bottom Up Approach
- 60. Debugging
- 61. Debugging • Debugging is a crucial skill. It involves detecting and removing existing and potential errors, defects, or ‘loopholes’ in one’s code.
- 63. Integrated Development Environment(IDE) • they are applications programmers use to write code and organize text groups. It increases a programmer’s efficiency and productivity, and has added features like code completion, code compilation, debugging, syntax highlighting, etc. • Some common examples of IDE’s are: • Visual Studio code • IntelliJ IDEA • NetBeans • Eclipse
- 65. IntelliJ IDEA Java and other JVM languages like Kotlin, Scala, and Groovy
- 67. Eclipse Eclipse is a free, Java-based development platform known for its plugins that allow developers to develop and test code written in other programming languages
