Program to calculate standard deviation using arrays by passing it to the function 



#include <stdio.h>
#include <math.h>
float standard_deviation(float data[], int n);
 int main()
{ int n, i; float data[100];
printf("Enter number of datas( should be less than 100): ");
 scanf("%d",&n); printf("Enter elements: ");
 for(i=0; i<n; ++i) scanf("%f",&data[i]);
printf("\n"); printf("Standard Deviation = %.2f", standard_deviation(data,n));
 return 0; }

float standard_deviation(float data[], int n)
 { float mean=0.0, sum_deviation=0.0; int i;
 for(i=0; i<n;++i) { mean+=data[i]; }
 mean=mean/n; for(i=0; i<n;++i)
 sum_deviation+=(data[i]-mean)*(data[i]-mean); return sqrt(sum_deviation/n); }
