The following are from the Algorithm Workbench in your book on page 140. You are to complete one of these three for your practice program 25. A retail store grants its customers a maximum amount of credit. Each customer's available credit is his or her maximum amount of credit minus the amount of credit used. Write a pseudocode algorithm for a program that asks for a customer's maximum amount of credit and amount of credit used. The program should then display the customer's available credit After you write the pseudocode algorithm, convert it to a complete C++ program
