Answer to Question #25078 in C++ for Dave

Question #25078
I am trying to make a program that will find pi to an imputed specificity. excerpt that's not working: cout << "\n OK, so how many values of Pi do you want?\n"; cin >> valuecount; cout << fixed << setprecision(valuecount) << 22/7 << endl; example: If i input 4, i get 1 digit, or "3", instead of "3.141" everything is already defined at the top: #include <cstdlib> #include <iostream> #include <windows.h> #include <iomanip>

#include <cstdlib>
#include <iostream>
#include <windows.h>
#include <iomanip>

using namespace std;

int main()
{
cout<<"How many values of PI do you want ?\n";

int valuesCount;
cin>>valuesCount;

//the problem was that you divide integer values but not double (use 22.0 instead of 22)
cout<<setprecision(valuesCount)<<22.0/7.0;

cin.get(); //suspend console
cin.get(); //suspend console

return 0;
}
