New to C++, help with code

[thegoldenking]

Hey guys I'm new to c++ and I was wondering if anyone could help me with my code? I need to make a code that can do the Pythagorean theorem with fractional components. I made a code that can do the theorem but I'm not sure how to do the fractional part. When ever I enter a fractional number in, the program assumes I'm giving values for both a and b instead of just one here is my code.

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


using namespace std;


int main ()
{
  
    float a, b, c;
    cout << "Optimal Driving Distance Calculator \nPlease input the distance of east:";
    cin >> a;
    cout << "Please input the distance of north:";
    cin >> b;
    


    c = a*a +b*b;
    c=sqrt(c);


    cout <<"The optimal driving distance is " << c << '.' << endl;


    system ("pause");
 
}

Thanks for you help!

As written, you will need to input decimal numbers. Entering in stuff like 1/4 isn't going to work without more programming. If your compiler has C++11 support, you can try using the ratio class, or program something similar yourself.
