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()

#include<stdio.h>
#include<conio.h>
#include<math.h>

void calc(int, int, int, int, int, int*, int*, float*);

int main()
{
	int a, b, c, d, e, sm, av;
	float sd;

	printf("Enter five numbers : ");
	scanf("%d%d%d%d%d", &a, &b, &c, &d, &e);

	calc(a, b, c, d, e, &sm, &av, &sd);

	printf("\nSum : %d\n\nAverage : %d\n\nStandard Deviation : %f\n", sm, av, sd);

	getch();
	return 0;
}
void calc(int a, int b, int c, int d, int e, int *sm, int *av, float *sd)
{
	int i;
	*sm = a + b + c + d + e;
	*av = *sm / 5;
	*sd = pow(a - *av, 2) + pow(b - *av, 2) + pow(c - *av, 2) + pow(d - *av, 2) + pow(e - *av, 2);
	*sd = sqrt(*sd / 5);
