Use your function declarations in Problem 1 to define two additional integer functions for power and factorial. Use your new function declarations to compute as a single expression the following:

(5! + 4!)³

Your main function should not declare a single variable, but it should print as output the result of computing this expression. Your implementation is correct if your output yields the value 2985984.

REF PRB:

Write a C++ program that defines value-returning functions for the arithmetic integer binary operations plus, minus, multiply, and divide. You should also write a value returning function for the unary operation negate. Use your function declarations to compute the following as a single expression:

–(((5–4)*(8/2))+7)

Your main function should not declare a single variable, but it should print as output the result of computing this expression. Your implementation is correct if your output yields the value –11.
