2. Compound (Block of) Statements
The if and if. . .else structures control only one statement at a time.
Suppose you want to execute more than one statement if the expression evaluates to true.
To permit this, c++ provides compound statements.

4. Multiple Selections: Nested if
Some problems require the implementation of more than two alternatives. You can include multiple selection in a program by using an if. . .else structure if the action statement itself is an if or if. . .else statement.
When one control statement is located within another, it is said to be nested.

6. switch Structures
there are two selection structures in C++. The first selection structure, which is implemented with if and if. . .else statements, usually requires the evaluation of a (logical) expression. The second selection structure, which does not require the evaluation of a logical expression, is called the switch structure. C++’s switch structure gives the computer the power to choose from among many alternatives.

7. A general syntax of the switch statement

10. Break statement
To see the effect of break statements, we will delete it from previous program and recompile it.
