I need help with a program in C++ Data Structures

Write a program to implement an abstract data type Rational-Numbers.  A Rational number has two parts, numerator and denominator.  Example 1/2 and 3/5 are rational numbers.  You can perform math operations on rational numbers and the results are rational numbers.  The following are the operations to implement.

Test the code with the following data:

Rational numbers:    a = 3/8,   b= 4/7, c = 1/5,  d = 4/12, e = 3/5   f = 4/1 and

                                                            g = 3/0 (your program should not error)

Compute and output the two rational numbers and their results:  a + b,      c * d,     d / e,    c

Add = alpha / beta + chi / delta = alpha delta + beta chi / beta delta Sub = alpha / beta - chi / delta = alpha delta - beta chi/beta delta Mult = alpha / beta * chi/delta = alpha chi + beta delta Div = alpha / beta/chi/delta = alpha delta / beta chi
