 Write a C Program to Find Sum, Average and Standard Deviation for a Given Set of Values

Source Code:

#include<stdio.h>

#include<conio.h>

#include<math.h>

void main()

{

float x[50];

int i,n;

float sum=0,avg,variance,stddev,d,varsum=0;

printf("\n Enter number of values\n");

scanf("%d",&n);

printf("\n Enter the values\n");

for(i=0;i<n;i++)

{

scanf("%f",&x[i]);

sum=sum+x[i];

}

avg=sum/(float)n;

for(i=0;i<n;i++)

{

d=x[i]-avg;

varsum=varsum+pow(d,2);

}

variance=varsum/(float)n;

stddev=sqrt(variance);

printf("\n Sum =%.2f",sum);

printf("\n Average =%.2f",avg);

printf("\n Standard Deviation =%.2f",stddev);

getch();

}

Output:
