This is a C++ Program!!! Define a class called Rational that would represent rational numbers. Write a constructor that would accept two integers and initialize the numerator and denominator of the object to their values. Also include a default constructor that would initialize the numerator to 0 and denominator to 1. Implement the member functions add, sub, mul, div, less, and equal to carry out the operations +, -, *, /, <, and == (i.e., a + b would be...

Show all steps , write clear
Let F be an infinite field. Show that for two polynomials f(X), 9(X) E we have that f(X) = g(X) if and only if f(t) = g(t) for all t e F. Is this still true if F is a finite field? (Consider the polynomials X and X2 on the field Z/2).
