Sum of Array Using Pointers – Write a C program to input n numbers in one dimensional array and find sum of all elements with pointer arithmetic. You will love to read Understanding C Pointers Basic Concepts before reading this program.

## C Program Sum of Array Using Pointers

```#include <stdio.h>
int main()
{
int a[50], i,n, sum=0;
int *ptr;
printf("\n Write a C Program To:");
printf("\n Input elements and Find Sum in");
printf("\n Array Using Pointers in C:");
printf("\n ------------------------------------\n");

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

ptr = a;

for(i=0;i<n;i++)
{
printf(" Enter Element a[%d] : ",i);
scanf("%d",ptr++);
}

ptr = a;
for(i=0;i<n;i++)
{
sum = sum + *ptr++;
}
printf(" Sum of Array Elements using Pointer=%d",sum);

return 0;
}
```

### Output

Write a C Program To:
Input elements and Find Sum in
Array Using Pointers in C:
——————————————
Enter the number of elements of the array:5
Enter Element a[0] : 10
Enter Element a[1] : 20
Enter Element a[2] : 100
Enter Element a[3] : 800
Enter Element a[4] : 1
Sum of Array Elements using Pointer=931
