﻿ C Program: Sum of values in a array except 17

C Exercises: Compute the sum of values in a given array of integers except the number 17

C-programming basic algorithm: Exercise-52 with Solution

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 integer.

C Code:

``````#include <stdio.h>
#include <stdlib.h>
int main(void){
int array1[] = {1, 2, 5, 7, 9, 10, 12, 17};
int arr_size = sizeof(array1)/sizeof(array1[0]);
printf("Sum of values in the array of integers except the number 17: ");
printf("%d",test(array1, arr_size));
}
int test(int nums[], int arr_size)
{
int sum = 0;

for (int i = 0; i < arr_size; i++)
{
if (nums[i] != 17) sum += nums[i];
else i++;
}
return sum;
}
``````

Sample Output:

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

Why doesn't a+++++b work?

printf("%d",a+++++b); is interpreted as (a++)++ + b according to the Maximal Munch Rule!.

++ (postfix) doesn't evaluate to an lvalue but it requires its operand to be an lvalue.
