# C Programming Example to find sum of array elements - 2 Examples

## Algorithm

1. Initialize an empty array
2. Take number of items in array, n
3. Loop upto n and take value
4. Assign value to the index of that array
5. Initialize a sum = 0
6. loop upto n and make sum = sum + array [index]
7. Print Sum

## Code Examples

### #1 Code Example with C Programming

```Code - C Programming```

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

int main()
{
int array[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", &array[i]);
}

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

printf("Sum = %d", sum);
return 0;
}``````
Copy The Code &

Input

cmd
Enter size of the array : 5
Enter elements in array : 1 2 3 4 5

Output

cmd
Sum = 15

### #2 C Program to find sum of array elements using Function

```Code - C Programming```

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

int sumOfArray(int array[], int n) {
int i = 0, sum = 0;

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

return sum;
}

int main()
{
int array[1000], i, n;

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

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

printf("Sum = %d", sumOfArray(array, n));
return 0;
}``````
Copy The Code &

Input

cmd
Enter size of the array : 6
Enter elements in array : 1 2 3 4 5 6

Output

cmd
Sum = 21
