Thread: Question?

This program I have written has the user enter a number and it will display the fibonacci number that is associated with that number. This part works what i need to know what do I need in my code so that a user can enter 0 or a negative number so they can quit. I want it so that it will ask the user to enter a number and give the fibonacci number until a user enters a 0 or a negative number then it will end the program.

Thanks,
Nate

#include <iostream.h>
#include <math.h>
#include <iomanip.h>

int main()
{
int count = 0;
int count2 = 1;
int count3 = 1;
int count4 = 0;
int num;



cout << "Enter a number (0 or a negative to quit): ";
cin >> num;




do
{

count3 = count + count2;
count2 = count;
count = count3;

count4 += 1;

}while ( count4 != num );

cout << "Fibonacci ( " << num << " ) = " << count3 << endl;




return 0;
