# C Exercises: Find the sum of all elements of an array

## C Array: Exercise-3 with Solution

Write a program in C to find the sum of all elements of an array.

Pictorial Presentation:

Sample Solution:

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

void main()
{
int a[100];
int i, n, sum=0;

printf("\n\nFind sum of all elements of array:\n");
printf("--------------------------------------\n");

printf("Input the number of elements to be stored in the array :");
scanf("%d",&n);

printf("Input %d elements in the array :\n",n);
for(i=0;i<n;i++)
{
printf("element - %d : ",i);
scanf("%d",&a[i]);
}

for(i=0; i<n; i++)
{
sum += a[i];
}

printf("Sum of all elements stored in the array is : %d\n\n", sum);
}
```
```

Sample Output:

```Find sum of all elements of array:
--------------------------------------
Input the number of elements to be stored in the array :3
Input 3 elements in the array :
element - 0 : 2
element - 1 : 5
element - 2 : 8
Sum of all elements stored in the array is : 15
```
