C Practice Exercise

Write a C program to calculate the sum of all numbers not divisible by 17 between two given integer numbers.

Sample Solution:

C Code:

#include <stdio.h>
int main() {
    int x, y, temp, i, sum=0;

    // Prompt for user input
    printf("\nInput the first integer: ");
    scanf("%d", &x);
    printf("\nInput the second integer: ");
    scanf("%d", &y);

    // Swap values if x is greater than y
    if(x > y) {
        temp = y;
        y = x;
        x = temp;
    }

    // Calculate the sum of numbers not divisible by 17
    for(i = x; i <= y; i++) {
        if((i % 17) != 0) {
            sum += i;
        }
    }

    // Display the sum
    printf("\nSum: %d\n", sum);

    return 0;
}

Sample Output:

Input the first integer: 50                                            
                                                                       
Input the second integer: 99                                           
                                                                       
Sum: 3521

Previous: Write a program that reads two numbers and divide the first number by second number. If the division not possible print "Division not possible".
Next: Write a C program to find all numbers which dividing it by 7 and the remainder is equal to 2 or 3 between two given integer numbers.
