C Program to Sum and Average of Array Elements using a Pointer

Program to sum and average of array elements using pointer in c; Through this tutorial, we will learn how to write a program for calculate or find sum and average of array elements using pointer in c.

C Program to Sum and Average of Array Elements using a Pointer

#include <stdio.h>

int main()
{
	int Size, sum = 0;

	printf("Please Enter the Array size = ");
	scanf("%d", &Size);

	int arr[Size];

	int *parr = arr;

	printf("Enter the Array Items = ");
	for (int i = 0; i < Size; i++)
	{
		scanf("%d", parr + i);
		sum = sum + *(parr + i);
	}

	float avg = (float)sum / Size;

	printf("\nThe Sum of Array Items     = %d\n", sum);
	printf("\nThe Average of Array Items = %.2f\n", avg);
}

The output of the above c program; is as follows:

Please Enter the Array size = 5
Enter the Array Items = 1 2 3 4 5
The Sum of Array Items     = 15

The Average of Array Items = 3.00
