I made this code to find pythagorean theorums...
But it won't work right..
any help?

Code:
#include <iostream>
#include <string>
using namespace std;

int main ()
{
int a,b,c,d,e;
d = a * a+ b* b;
d = c * c;
cout << "Welcome to the LZ Pythagorean Theorem Finder" << endl << "To use this application, enter the values of variable A and B" << endl;
cout << "A = ";
cin >> a;
cout << "B = ";
cin >> b;
cout << "C = " << c << endl;

return 0;
}
