sum,average and standard deviation

Write a function that receives 5 integers and returns the sum, average and standard deviation of these numbers. Call this function from main( ) and print the results in main( ).  

solution 

	#include <stdio.h>
	#include <stdlib.h>
	#include <ctype.h>
	#include <math.h>
	#include <stdbool.h>
	void sum_avg_dev(int data[5],int *sump,double *avgp,double *devp)// accept numbers as array elements and three pointers treated as function output parameters
	{
	for(int i=0;i<5;i++)
	{
	*sump+=data[i];//sum
	}
	*avgp=*sump/5.0;//average
	int sumsqr=0;
	for(int i=0;i<5;i++)
	{
	sumsqr+=data[i]*data[i];
	}
	*devp=sumsqr/5.0;//std deviation
	return ;
	}
	int main()
	{
	int sum=0; double avge=0.0; double dev=0.0;int array[5];
	printf("enter five integers\n");
	for(int i=0;i<=4;i++)
	{
	scanf("%d",&array[i]);
	}
	sum_avg_dev(array,&sum,&avge,&dev);
	printf("sum= %d\naverage= %lf\nstandard deviation= %lf\n",sum,avge,dev);
	return 0;
	}
