C Exercises: Compute the sum of the elements of a given array of integers

Last update on December 20 2024 13:00:33 (UTC/GMT +8 hours)

Write a C program to compute the sum of the elements of an array of integers.

C Code:

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

// Function prototype for 'test'
int test(int a1[]);

int main(void){
    // Declaration and initialization of arrays
    int array1[] = {10, 20, 30, 40, 50};
    int array2[] = {10, 20, -30, -40, 50};

    // Printing the result of calling 'test' function with different arrays
    printf("%d", test(array1));
    printf("\n%d", test(array2));
}

// Definition of the 'test' function
int test(int a1[])
{
    // Adding up the elements of the array and returning the result
    return a1[0] + a1[1] + a1[2] + a1[3] + a1[4];
}

Sample Output:

150
10

Previous: Write a C program to check a given array of integers of length 1 or more and return true if the first element and the last element are equal in the given array.
Next: Write a C program to rotate the elements of a given array of integers (length 4 ) in left direction and return the new array.
