Overview of C++ Statements

C++ statements are executed sequentially, except when an expression statement, a selection statement, an iteration statement, or a jump statement specifically modifies that sequence.

labeled-statement
expression-statement
compound-statement
selection-statement
iteration-statement
jump-statement
declaration-statement
try-throw-catch

In most cases, the C++ statement syntax is identical to that of ANSI C. The primary difference between the two is that in C, declarations are allowed only at the start of a block; C++ adds the declaration-statement, which effectively removes this restriction. This enables you to introduce variables at a point in the program where a precomputed initialization value can be calculated.

Declaring variables inside blocks also allows you to exercise precise control over the scope and lifetime of those variables.

The topics on statements describe the following C++ keywords:
