Syntax:
if (expression)
statement;
[else
statement;]
The expression must evaluate to a boolean value, where zero is false and all non-zero values are true. The statement (including the optional else statement) may be simple or compound, and may include a nested if statement. When the expression evaluates true, the first statement is invoked. If an else statement is provided, it is only executed when the expression evaluates false. After the appropriate statement is invoked, execution passes to the statement that immediately follows the entire if statement.
