int main(void)

{
	
	int *a,n,i,sum=0;

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

	a=malloc(sizeof(int)*n);

	printf("Enter %d Elements:",n);
	for(i=0;i<n;i++)

	{

		scanf("%d",&a[i]);

	}

	for(i=0;i<n;i++)
	
	{

		sum=sum+a[i];

	}

	printf("The sum of Array is: %d",sum);	
	return 0;

}

Program Explanation

i is initialized to 0 and incremented by 1 at each iteration of both the for loops.

First for loop reads n input numbers from user and stores them in array a[] from location 0 to n-1

Second for loop adds all the n elements of array located from 0 to n-1

Finally prints the sum using printf statement.
