In Chapter 1, we talked about the four basic structures for expressing actions in a programming language: sequence, selection, loop, and subprogram. We said that subprograms allow us to write parts of our program separately and then assemble them into final form. In C++, all subprograms are referred to as functions, and a C++ program is a collection of one or more functions. |

Each function performs some particular task, and collectively they all cooperate to solve the entire problem. |
