WAP to calculate standard deviation and mean

Write a program to calculate standard deviation and mean

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

int main() {
	int N,i;
	float n,sum=0,sqrSum=0,mean,SD;
	printf("Enter number of numbers \nN=");
	scanf("%d",&N);
	for(i=1;i<=N;i++) {
		printf("Enter number %d: ",i);
		scanf("%f",&n);
		sum+=n;
		sqrSum+=n*n;
	}
	mean=sum/N;
	SD=sqrt((sqrSum/N)-mean*mean);
	printf("Mean: %.3f\n",mean);
	printf("S.D: %.3f",SD);
	return 0;
}
