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
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.
