IF ... THEN ... ELSEIF Statement

It is also same as IF .. THEN statement, but the only difference is that, by using IF .. THEN statement we can test only one condition, and based on the condition given block of statement will be executed. But what? If we have more than one condition? At that time we have to use IF ... THEN ... ELSEIF statement. It is also called a multi-way decision statement.

Syntax:

 
IF [condition] THEN
        [statement 1]
ELSEIF
        [statement 2]
ELSEIF
 [statement n]
........................
.......................
ELSE
        [statement n]
END IF

Example 1

CLS
INPUT "Enter First Number "; x
INPUT "Enter Second Number "; y
INPUT "Enter Third Number "; z
IF x > y AND x > z THEN
     PRINT "Greatest number is "; x
ELSEIF y > x AND y > z THEN
     PRINT "Greatest number is "; y
ELSE
     PRINT "Greatest number is "; z
END IF
END

Example 2

 CLS
INPUT "Enter your percentage "; p
IF p >= 80 THEN
     div$ = "Distinction"
ELSEIF p >= 60 THEN
     div$ = "First Divistion"
ELSEIF p >= 40 THEN
     div$ = "Second Division"
ELSEIF p >= 35 THEN
     div$ = "Third Division"
ELSE
    div$ = "Fail"
END IF
PRINT "Division ::: "; div$
END
