WHAT DID YOU NOTICE?
Both the programs have two IF conditions joined together using AND or OR. The final result
depends on the combined result.
AND: Results in true only if both the conditions are true. If any one condition is false, the result
will be false.
OR: Results in true if at least one of the conditions is true. If both are false, the result will be
false.
Now, write your answers for both.
1. age =20 2. shop = 500
IF age >= 12 AND age <= 19 THEN customer = "new"
PRINT "You are a teenager" IF shop > 100 OR customer = "old" THEN
ELSE PRINT "Eligible for a free gift"
PRINT "You are not a teenager" ELSE
PRINT "Not eligible for a free gift
LOOPS IN A PROGRAM
A loop allows a set of instructions or a block of code to be executed repeatedly. It helps in
automating repetitive tasks and makes the code more efficient by avoiding the need to write the
same instructions multiple times. When a loop repeats forever (endlessly), it is called an infinite
loop. There are two types of loops.
Counting loops: These repeat a block of code a specific number of times.
Conditional loops: These repeat until a certain condition is reached, which means they keep
going until the condition remains true.
