Introduction to C Programming

1. Developed by Dennis Ritchie at Bell Labs in the early 1970s.
2. Known for its efficiency, simplicity, and low-level system access.
3. Follows a procedural programming paradigm.
4. Focuses on functions and structured programming.
5. Highly portable language, allowing programs written in C to run on different platforms with minimal modifications.
6. C uses a syntax that includes variables, data types, operators, and control structures (loops and conditionals).
7. To run C/C++ in your system you need two things:
   • MinGW compiler: Search for “mingw compiler downloader” in Google, install it, and set the environment variable by giving the compiler path.
   • Code Editor/IDE: Download VS Code. (Avoid DevC++/Turbo C as they are discontinued.)
   • Create a file in your editor with a .c extension.
   • Install Code Runner Plugin in VS Code to easily run code in the IDE, or use the terminal for manual compilation.

Hello World in C

hello.c

#include <stdio.h>

int main() {
    printf("Hello, World!\n");
    return 0;
}
