a dollar to get her integers

I'm seriously on the brink of a real update, I just wanted to share this. It's my homework for CS 158, my first course in C programming. It's a very simple program that asks for the sides of a triangle (in inches) and calculates the hypotenuse (in centimeters), but I'm damn proud of it.
