C For Loop

Used to iterate a specific number of times.

Syntax:
for (initialization; condition; update) {
// Code to be executed in each iteration
}

1. Initialization - It initializes the variable for the loop to process.
2. Condition - Checks the condition before iteration. If false it exits the loop.
3. Update - It increments or decrements the variable used to initilize the loop.

#include <stdio.h>

int main() {
    // Print numbers from 1 to 5 using a for loop
    for (int i = 1; i <= 5; i++) {
        printf("%d ", i);
    }

    return 0;
}

See how the loop works

1. int i = 1 initializes the variable i to 1.
2. i <= 5 is the condition that checks if i <= 5.
3. i++ increments the value of i after each iteration

Using Arrays

#include <stdio.h>

int main() {
    // Iterating through an array
    int numbers[] = {10, 20, 30, 40, 50};
    
    for (int i = 0; i < 5; i++) {
        printf("%d ", numbers[i]);
    }

    return 0;
}
