If Else Statement
In the If Else statement structure, if the condition given is ‘True’, then the statement specifi ed
within If block is executed. If the condition is ‘False’, the statement following Else will be
executed. Let’s understand If Else statement with the syntax and an example.

Syntax:

If (Test condition)
{
False True
................................................... Condition

Statements x
} Statements y Statements x
Else

{
...................................................
Rest of the code
Statements y
}

Example: Write a program to fi nd the smallest of two numbers.

If Else If Ladder

If Else If ladder is used to check multiple conditions in a program. This can be executed by
including multiple Else If statements. If the condition written inside the If block is ‘True’, the
statement associated with that gets executed, and the rest of the ladder is skipped. The
statement inside an Else block is executed only when all the conditions that come before it in
the ladder are ‘False’. But at a time only one condition can be executed.

Let’s understand If Else If ladder with the syntax and an example.
