It helps the computer to check whether the relation is TRUE or FALSE.
Syntax: Line Number IF ( relational expression) THEN n where n is a line number or an instruction. If the expression is true then n will be executed otherwise statement following IF..THEN statement will be executed.
It is a decision making statement as it decides the path of the program.
Syntax: If (Condition) ...THEN (Line number or instruction) .....ELSE (Line number or instruction)
IF_ _ _ _ _ ELSEIF Statement
Syntax: IF ( Condition ) THENStatement-1ELSEIF (Condition) THENStatement-2ELSEIF (Conditon) THENStatement-ELSEStatement-4ENDIF
Syntax: SELECT CASE ( expression )
Case ( expression )
