• If the boolean expression yields false and if an else part if present, control is transferred to the second embedded statement. When and if control reaches the end point of that statement, control is transferred to the end point of the if statement.
• If the boolean expression yields false and if an else part if not present, control is transferred to the end point of the if statement.
• if statements can be nested.
