C Program to find the sum and average of array Elements

Get array size n and n elements of array, then compute sum and average of the elements.

Sample Input 1:

5 5 7 9 3 1

Sample Output 1:

25 5.0

Program or Solution

#include <stdio.h>
#include <stdlib.h>

int main(void)

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

	printf("Enter size of array:");


	printf("Enter %d Elements:",n);







	printf("\nSum of array:%d \nAverage of Array:%d",sum,avg);	
	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 compute average using avg=sum/n statement and prints average avg using printf statement.
