C Program to Find Sum and Average of an Array Using the Pointer. Take input from the end-user for the array of numbers, calculate sum and average. Later display those results to the screen. Use the pointer to perform all these operations. Here, we will develop a program to find sum and average of an array using the pointer in c.
#include<stdio.h>
int main()
{
float x[5], sum=0.0, avg;
int i;
float *px, *psum, *pavg;
px = &x[0]; // Or, px = &x;
psum = &sum, pavg = &avg;
printf("Enter array Elements: ");
for (i=0;i<5;i++)
{
scanf("%f",(px+i));
*psum += *(px + i);
}
*pavg = *psum / 5;
printf("Sum= %.2f \t Average= %.2f\n", *psum, *pavg);
return 0;
}Output:-
Enter array Elements: 10
24
30
62
15
Sum=141.00 Average=28.20
