IF-ELSE Statement
The above mentioned logic can be applied through if-else statement. The if-else statement
requires three things:
Evaluation statement: Condition or expression that is being checked.
Execution statement: Operations which will be performed if the condition appears to
be true.
Else execution block: Operation which will be performed only if the evaluation statement
is false.
Subject Enrichment
Example: To check if a number is even or odd by using if-else statement.
Flowchart: Start
Read a
number
Is the number No The number is odd
divisible by 2?
Yes
The number is even
End
Explanation: To implement this in a program, you will use, number%2=0, i.e., we divide the
number by 2 and if the remainder comes out to be 0, then the number is even, otherwise
the number is odd.
ELSE-IF Statement
Suppose you need to compare two numbers a, b and check if a is greater than b or they are
equal. To implement this, you need to check two conditions.
In python, the keyword elif, is used for checking another statement in case the previous
statement is false.
Code:
a=23
b=23
