For Loops

Simple C for loop

#include <stdio.h>

int main() {
    for (int i = 1; i <= 5; i++) {
        printf("Number: %d\n", i);
    }
    
    return 0;
}

For loop with custom step

#include <stdio.h>

int main() {
    for (int i = 0; i <= 10; i += 2) {
        printf("Even number: %d\n", i);
    }
    
    return 0;
}

C for loop with basic iteration

#include <stdio.h>

int main() {
    for (int i = 1; i <= 10; i++) {
        printf("Number: %d\n", i);
    }
    
    return 0;
}

C for loop with custom step size

#include <stdio.h>

int main() {
    for (int i = 0; i <= 20; i += 2) {
        printf("Even number: %d\n", i);
    }
    
    return 0;
}

C for loop processing array elements

#include <stdio.h>

int main() {
    int arr[] = {10, 20, 30, 40, 50};
    int size = sizeof(arr) / sizeof(arr[0]);
    
    for (int i = 0; i < size; i++) {
        printf("arr[%d] = %d\n", i, arr[i]);
    }
    
    return 0;
}

C nested for loops creating pattern

#include <stdio.h>

int main() {
    for (int i = 1; i <= 5; i++) {
        for (int j = 1; j <= i; j++) {
            printf("* ");
        }
        printf("\n");
    }
    
    return 0;
}

C for loop with multiple variables

#include <stdio.h>

int main() {
    for (int i = 1, j = 10; i <= 5; i++, j--) {
        printf("i = %d, j = %d\n", i, j);
    }
    
    return 0;
}

C for loop processing string characters

#include <stdio.h>
#include <string.h>

int main() {
    char str[] = "Programming";
    
    for (int i = 0; i < strlen(str); i++) {
        printf("Character %d: %c\n", i, str[i]);
    }
    
    return 0;
}

C for loop with multiple variables and conditions

#include <stdio.h>

int main() {
    for (int i = 0, j = 10; i < 5 && j > 5; i++, j--) {
        printf("i = %d, j = %d\n", i, j);
    }
    
    return 0;
}

C for loop with break and continue statements

#include <stdio.h>

int main() {
    for (int i = 1; i <= 10; i++) {
        if (i == 3) {
            continue;  // Skip iteration
        }
        if (i == 8) {
            break;     // Exit loop
        }
        printf("Number: %d\n", i);
    }
    
    return 0;
}
