#WSQ10

#TC1017

This is my lists program, which makes the sum, average and standard devation of 10 given numbers.

#include <iostream>

#include <cmath>

#include <string>

using namespace std;

double List[10];

double SUM(double List[])

{

double sum;

for (int i=0;i<10;i++)

{

sum=sum+List[i];

}

return sum;

}

double DES(double List[])

{

double des, pcg;

for(int i=0;i<10;i++)

{

pcg=pcg+(List[i]/10);

}

for(int i=0;i<10;i++)

{

double po, res;

res=(List[i]-pcg);

po=pow(res,2);

des=des + po;

}

des=des/10;

des=sqrt(des);

return des;

}

int main()

{

double sum, des;

string ans;

do

{

cout<<“Please enter 10 numbers.”<<endl;

for (int i=0;i<10;i++)

{

cout<<“Enter the “<<i+1<<“° value.”<<endl;

cin>>List[i];

}

sum=SUM(List);

cout<<“The sum of the 10 numbers that you entered is: “<<sum<<endl;

cout<<“The average result of the 10 numbers that you entered is: “<<sum/10<<endl;

des=DES(List);

cout<<“The standard dev. of the 10 numbers you entered is: “<<des<<endl;

cout<<“Do you want to try again?”<<endl;

cin>>ans;

}while(ans==”y”);

cout<<“OK. Goodbye.”<<endl;

return 0;
