Tag: cycle

This code reads barrel diameter and height from file, then, based on dimension make decisions and finally these decisions are printed out to a file. My pronbelm is how to avoid using the code wrtine on lines 70-101? Probably has to do with line 35, but I haven´t figured my way around it. Would be nice if there is a way (chance) to make this code shorter.

P.S d – diameter, h – height
