Chapter Summary

C++ provides a fairly limited number of statements. Most of these affect the flow of control within a program:

while, for, and do while statements, which implement iterative loops

if and switch, which provide conditional execution

continue, which stops the current iteration of a loop

break, which exits a loop or switch statement

goto, which transfers control to a labeled statement

TRy, catch, which define a TRy block enclosing a sequence of statements that might throw an exception. The catch clause(s) are intended to handle the exception(s) that the enclosed code might throw.

throw expressions, which exit a block of code, transferring control to an associated catch clause

There is also a return statement, which will be covered in Chapter 7.

In addition, there are expression statements and declaration statements. An expression statement causes the subject expression to be evaluated. Declarations and definitions of variables were described in Chapter 2.
