**I REVISED MY PROGRAM**

```
#include <iostream>
#include <cmath>
using namespace std;
int main ()
{
const int num=100;
float volt[num], sum=0, sum2=0 ;
double ave2,standrddev1, standrddev2, standrddev;
float average;
int i, k=0 ;
{
cout<<"Enter the number of voltages to be analyzed:";
cin>>k;
if (k>100)
{
cout<<"Maximum of 100 voltages can only be analyzed.";
}
}
while (k>100);
for (i=0; i<k; i++)
{
cout<<"ENTER VOLTAGE "<<i+1<<":";
cin>>volt[i];
sum=sum+volt[i];
}
average=sum/k;
cout<<endl<<"The average of the voltage is:"<<average<<endl;
cout<<endl;
for (i=0; i<k; i++)
{
volt[i]=pow((average-volt[i]),2);
sum2=sum2+volt[i];
ave2=sum2/k;
standrddev1=(sqrt,ave2);
standrddev2=standrddev1/k;
standrddev=standrddev2*2;
cout<<endl<<"The standard deviation of the voltages is:"<<standrddev<<endl;
return 0;
}
}
