// String Length with For Loop
#include <stdio.h>

int main() {
    char str[] = "Hello World"; // The string to measure
    int length = 0;              // Variable to store the length
    
    // Step 1: Iterate through the string using a for loop
    // The loop continues as long as the current character is not the null terminator '\0'
    for (int i = 0; str[i] != '\0'; i++) {
        // Step 2: Increment the length counter for each character found
        length++;
    }
    
    // Step 3: Print the calculated length
    printf("The string is: \"%s\"\n", str);
    printf("Length of the string (for loop): %d\n", length);
    
    return 0;
