ALGORITHMIC INTELLIGENCE
CONDITIONS IN A PROGRAM
While writing a program, we need to make certain decisions based on the logic of the
program. Such situations are called conditions. Conditional statements are used in
a program to instruct the computer to make a decision. The result of the computer’s
decision for a condition will always be either a true or a false.
if-then-else
The program executes the statements written after ‘if’ when the condition is true. If it is
false, the statements written after ‘else’ will be executed.
Computational Thinking
Yes If (Condition) No
to be checked
Then Else
Do this Do that
Look at these examples:
Example 1: Example 2:
If Read marks
It is Maths class If marks is > 50
Then Display Pass
Take out Maths book & notebook Else
Display Fail
Example 3: Example 4:
If If
It is raining Number is divisible by 2
Then Then
Carry an umbrella Print “The number is EVEN”
Else Else
Do not carry an umbrella Print “The number is ODD”
