C Program to Calculate the Sum of the Array Elements using Pointer

#include < stdio.h>
#include 
 
void main()
{
    int i, n, sum = 0;
    int *a;
 
    printf("Enter the size of array A \n");
    scanf("%d", &n);
    a = (int *) malloc(n * sizeof(int));
    printf("Enter Elements of First List \n");
    for (i = 0; i < n; i++)
    {
        scanf("%d", a + i);
    }
        for (i = 0; i < n; i++)
    {
        sum = sum + *(a + i);
    }
    printf("Sum of all elements in array = %d\n", sum);
}

Output

 Enter the  size  of array A
 5 
Enter Elements of First List
 4 
 9 
 10 
 56 
 100 
Sum of all elements  in  array =  179
