Homework Help, please... [cout, cin]

[rharvison]

Hi all. I am very new at this stuff; first C++ Programming class with no background whatsoever. We are asked to create the design work and coding to generate an invoice given certain criteria. I wrote the program using the info and directives provided but I am coming up with 5 errors in the compiler that I cannot seem to correct [nor know how to do.] Please see below and let me know if anyone can provide any help. I am using a d/l C++ compiler from DEV-C++. A million and one thanks. -R

cin and cout are part of the standard namespace. Early on, use this:

using namespace std; // after the #includes

Since you

cin >> base_cost;

you shouldn't make it const.

float base_cost = 50.00, // base cost of rental

Statements end in a semicolon.

rental_cost = base_cost + (cost_daily * n_days);
tax = rental_cost * .07;
total_cost = rental_cost + tax;
sec_dep = total_cost * .10;
bal_due = total_cost - sec_dep;

Thanks so much for getting back to me so quickly. I will try to do what you said. Hope you don't mind if I keep your email address??? You're great! Again, thanks. -R
