A symbolic constant is a constant that is represented by a name, just as a variable is represented. Unlike a variable, however, after a constant is initialized, its value can't be changed.

There are two ways to declare a symbolic constant in C++. The old, traditional,and now obsolete way is with a preprocessor directive, #define. DefiningConstants with #define To define a constant the traditional way, you would enterthis:#define studentsPerClass 15
