52. Sum Array Excluding 17

Write a C program to compute the sum of values in a given array of integers except the number 17. Return 0 if the given array has no integers.

C Code:

#include <stdio.h>
#include <stdlib.h>

// Function prototype for 'test'
int test(int nums[], int arr_size);

int main(void){
    // Declaration and initialization of an integer array 'array1'
    int array1[] = {1, 2, 5, 7, 9, 10, 12, 17};

    // Calculating the size of the array 'array1'
    int arr_size = sizeof(array1)/sizeof(array1[0]);

    // Printing a message indicating the purpose of the program
    printf("Sum of values in the array of integers except the number 17: ");

    // Printing the result of the 'test' function for the array 'array1'
    printf("%d",test(array1, arr_size));
}    

// Definition of the 'test' function
int test(int nums[], int arr_size)
{
    // Declaration of a variable 'sum' to accumulate the sum of values
    int sum = 0;

    // Looping through the elements of the array
    for (int i = 0; i < arr_size; i++)
    {
        // Checking if the current element is not equal to 17
        if (nums[i] != 17)
        {
            // Adding the value to 'sum' if it's not equal to 17
            sum += nums[i];
        }
        else
        {
            // Skipping the element if it is equal to 17
            i++;
        }
    }

    // Returning the accumulated sum
    return sum;
}

Sample Output:

Sum of values in the array of integers except the number 17: 46
