Sum Array Elements 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.

Sample Solution:

C++ Code :

#include <iostream>  // Including input-output stream header file

using namespace std;  // Using standard namespace

// Function definition that calculates the sum of values in the array excluding the number 17
static int test(int nums[], int arr_length)
{
    int sum = 0;  // Initializing variable to store the sum

    // Loop through the array to calculate the sum of values excluding 17
    for (int i = 0; i < arr_length; i++)
    {
        if (nums[i] != 17)  // Checking if the current number is not equal to 17
            sum += nums[i];  // Adding the number to the sum if it's not 17
    }

    return sum;  // Returning the sum of values excluding 17
}

int main() 
{  
    int nums1[] = { 1, 5, 7, 9, 10, 17 };  // Initializing array nums1 with various integers including 17
    int arr_length = sizeof(nums1) / sizeof(nums1[0]);  // Calculating length of array nums1

    // Displaying a message about the sum of values in the array excluding the number 17
    cout << "Sum of values in the array of integers except the number 17:" << endl;
    // Calling test function with nums1 and displaying the sum of values excluding 17
    cout << test(nums1, arr_length) << endl; 

    return 0;  // Returning 0 to indicate successful completion of the program
}

Sample Output:

Sum of values in the array of integers except the number 17:
32

Previous: Write a C++ program to compute the difference between the largest and smallest values in a given array of integers and length one or more.
Next: Write a C++ program to compute the sum of the numbers in a given array except those numbers starting with 5 followed by atleast one 6. Return 0 if the given array has no integer.
