4. The Else There is no THEN like in Pascal or BASIC The else is optional
The statement to do if condition is true immediately follows the parenthesized condition
The else is optional
Else is a reserved word and signals the start of the statement to execute if the condition is false
The if without an else means else do nothing

5. Compound statements
Either the then statement or the else statement may be replaced with a compound statement
In any combination
Even the compound statement of an if may create local variables
Their scope is confined to the compound statement
