In any function, the return statement will terminate the current function and return control to the invoking function. That s why a return statement in main() terminates the program. There are actually four ways to terminate a program abnormally (i.e., before execution reaches the end of the main block): 1. use a return statement in main(); 2. call the exit() function; 3. call the abort() function; 4. throw an uncaught exception. The exit() and abort() functions are described in Appendix F. The exit() function is defined in the <cstdlib> header. It is useful for terminating a program from within a function other than main(). This is illustrated by the next example. EXAMPLE 5.24 Using the exit() Function to Terminate a Program

5.16 DEFAULT ARGUMENTS In C++ the number of arguments that a function has can vary during run-time. This is done by providing default values for the optional arguments. EXAMPLE 5.25 Default Parameters
This function evaluates the third degree polynomial a0 + a1x + a2x2 + a3x3. The actual evaluation is done using Horner s Algorithm, grouping the calculations as a0 + (a1 + (a2 + a3x)x)x for greater efficiency: double p(double, double, double=0, double=0, double=0);
int main() { // tests the p() function: double x = 2.0003; cout << "p(x,7) = " << p(x,7) << endl; cout << "p(x,7,6) = " << p(x,7,6) << endl; cout << "p(x,7,6,5) = " << p(x,7,6,5) << endl; cout << "p(x,7,6,5,4) = " << p(x,7,6,5,4) << endl; } double p(double x, double a0, double a1, double a2, double a3) { // returns a0 + a1*x + a2*x^2 + a3*x^3: return a0 + (a1 + (a2 + a3*x)*x)*x; } p(x,7) = 7 p(x,7,6) = 19.0018 p(x,7,6,5) = 39.0078 p(x,7,6,5,4) = 71.0222
The call p(x,a0,a1,a2,a3) evaluates the third-degree polynomial a0 + a1x + a2x2 + a3x3. But since a1, a2, and a3 all have the default value 0, the function can also be called by p(x,a0) to evaluate the constant polynomial a0, or by p(x,a0,a1) to evaluate the first-degree polynomial a0 + a1x, or by p(x,a0,a1,a2) to evaluate the second-degree polynomial a0 + a1x + a2x2. Note how the default values of 0 are given in the function prototype. For example, the call p(x,7,6,5), which is equivalent to the call p(x,7,6,5,0), evaluates the second degree polynomial 7 + 6 x + 5 x2.
In the example above, the function may be called with 2, 3, 4, or 5 arguments. So the effect of allowing default parameter values is really to allow a variable number of arguments passed to the function. If a function has default parameter values, then the function s parameter list must show all the parameters that have default values to the right of those that don t, like this:
