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.

Declaring variables inside blocks also allows you to exercise precise control over the scope and lifetime of those variables.
The articles on statements describe the following C++ keywords:
