Popular Programming Languages

Focus on introducing three languages:
- C Programming
- Java Programming
- Python Programming
Concepts primarily illustrated with C, followed by comparisons to Java and Python.

Environment Setup

Preparing your programming environment is crucial before coding.
Necessary setup includes software installations to write, compile, and execute programs.
Example of basic code structure given in C with the "Hello, World!" program.

Understanding the C Program Structure

Every C program starts with the main() function, followed by braces that enclose the program's body.
Example code illustrates the use of the printf() function for output.

Functions in Programming

Functions are modular units that perform specific tasks within a program.
main() serves as the entry point, while functions like printf() are used for output.
Possibility to create custom functions alongside built-in ones in C.

Comments in C

Comments enhance code readability and user-friendliness, allowing programmers to add explanations or notes within the code.
