C Program to find the sum and average of array Elements

Description

```Get array size n and n elements of array, then compute sum and average of the elements.
Input:
5
5 7 9 3 1
Output:
25
5.0```

Solution

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

int main(void)

{

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

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];

}

avg=sum/n;
printf("\nSum of array:%d \nAverage of Array:%d",sum,avg);
return 0;

}```

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.```
