how to sum an array in c code example

Example 1: sum of array in c

//made by Kashish Vaid
#include <conio.h>
 
 
int main()
{
    int a[1000],i,n,sum=0;
   
    printf("Enter size of the array : ");
    scanf("%d",&n);
 
    printf("Enter elements in array : ");
    for(i=0; i<n; i++)
    {
        scanf("%d",&a[i]);
    }
 
    
    for(i=0; i<n; i++)
    {
         
        sum+=a[i];
    }
     printf("sum of array is : %d",sum);
 
    return 0;
}

Example 2: sum of arrays

/**
 * C program to find sum of all elements of array
 */

#include <stdio.h>
#define MAX_SIZE 100

int main()
{
    int arr[MAX_SIZE];
    int i, n, sum=0;

    /* Input size of the array */
    printf("Enter size of the array: ");
    scanf("%d", &n);

    /* Input elements in array */
    printf("Enter %d elements in the array: ", n);
    for(i=0; i<n; i++)
    {
        scanf("%d", &arr[i]);

        // Add each array element to sum
        sum += arr[i];
    }

    printf("Sum of all elements of array = %d", sum);

    return 0;
}
