This section describes the details of the mechanisms used by C++ for plugging in an argument for a formal parameter when a function is invoked There are two basic kinds of parameters and therefore two basic plugging-in mechanisms in C++ The two basic kinds of parameters are call-by-value parameters and call-by-reference parameters All the parameters that appeared before this point in the book were call-by-value parameters With call-by-value parameters, only the value of the argument is plugged in With call-by-reference parameters, the argument is a variable and the variable itself is plugged in; therefore, the variable s value can be changed by the function invocation A call-by-reference parameter is indicated by appending the ampersand sign, &, to the parameter type, as illustrated by the following function declarations:

A call-by-value parameter is indicated by not using the ampersand The details on call-by-value and call-by-reference parameters are given in the following subsections

Call-by-value parameters are more than just blanks that are lled in with the argument values for the function A call-by-value parameter is actually a local variable When the function is invoked, the value of a call-by-value argument

is computed and the corresponding call-by-value parameter, which is a local variable, is initialized to this value In most cases, you can think of a call-by-value parameter as a kind of blank, or placeholder, that is lled in by the value of its corresponding argument in the function invocation However, in some cases it is handy to use a call-by-value parameter as a local variable and change the value of the parameter within the body of the function de nition For example, the program in Display 41 illustrates a call-by-value parameter used as a local variable whose value is changed in the body of the function de nition Notice the formal parameter minutesWorked in the de nition of the function fee It is used as a variable and has its value changed by the following line, which occurs within the function de nition:
