## C-programming basic algorithm: Exercise-56 with Solution

Write a C program to check if the sum of all 5' in the array exactly 15 in a given array of integers.

C Code:

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

int main(void){
int arr_size;
int array1[] = {1, 5, 6, 9, 10, 17};
arr_size = sizeof(array1)/sizeof(array1);
printf("%d",test(array1, arr_size));
int array2[] = {1, 5, 5, 5, 10, 17 };
arr_size = sizeof(array2)/sizeof(array2);
printf("\n%d",test(array2, arr_size));
int array3[] = {1, 1, 5, 5, 5, 5};
arr_size = sizeof(array3)/sizeof(array3);
printf("\n%d",test(array3, arr_size));
}
int test(int nums[], int arr_size)
{
int sum = 0;

for (int i = 0; i < arr_size; i++)
{
if (nums[i] == 5)
sum += 5;
}
return sum == 15;
}
``````

Sample Output:

```0
1
0
```
