Check out example codes for "sum of arrays". It will help you in understanding the concepts better.

Code Example 1

``````/**
* 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
*/
for(i=0; i<n; i++)
{
sum = sum + arr[i];
}

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

return 0;
}``````
