You must make sure that you never have _qs zero[1]. Your Rational number must be stored in reduced form, that is, _p and _q must be relatively prime. You must not use any built-in functions In RationalMain.cpp, write a test main to test your code. Uvivu. UUUJIH, LULU PUU9 must be relatively prime. You must not use any built-in functions In RationalMain.cpp, write a test main to test your code. Submit these four files via the drop-box [1] _q cannot be zero for Rational numbers. We have added an additional constraint that _q must be greater than zero. This does not mean that a _g
