C Practice Exercise

Write a C program to calculate the value of S where S = 1 + 1/2 + 1/3 + … + 1/50.

Sample Solution:

C Code:

#include <stdio.h>
int main() {
    float S = 0;
    int i;
    
    // Loop to calculate the sum
    for(i=1; i<=50; i++) {
        S += (float)1/i;
    }
    
    // Print the result
    printf("Value of S: %.2f\n", S);

    return 0;
}

Sample Output:

Value of S: 4.50
