C Loops Introduction

🔁 C Loops Introduction – Repeat Code Efficiently

Loops are powerful tools in C that let you run a block of code multiple times — like telling your computer, “Hey, repeat this until I say stop!” There are three main types of loops in C:

  • while loop – checks the condition first, then runs
  • for loop – best when you know how many times to repeat
  • do-while loop – runs first, then checks the condition

📝 Example: Printing Numbers Using while Loop

This program prints numbers from 1 to 5 using a while loop.

#include <stdio.h>

int main() {
    int i = 1;

    while (i <= 5) {
        printf("Number: %d\n", i);
        i++;
    }

    return 0;
}

🎯 Why Use Loops?

  • They reduce repetition in code.
  • They're essential for processing arrays, files, and user input.
  • Less typing, more logic!
