use a loop and make a variable where every element of the array will be added to it

have to use function or other ???????

do you mean you need to use a function for the adding process?
then just pass the array to a function (as a parameter) then do the same process as I stated before
e.g.
in main:

sum = totalofarray(ben);

at function:

int totalofarray(int ben[]){
int total;
//do process of adding values to total
return total;
}

#include <stdio.h>
void main()
{
int i, square,n,sum=0;
printf("enter the limit:");
scanf("%d",&n);
for(i=1;i<=n;i++)
{
square=sqr(i);
sum=sum+square;
printf(" \n the square of %d is %d",i,square);
}
printf(" \n sum of sqaure is %d is",sum);
}
int sqr(int a)
{
return(a*a);
}
