1. Write a simple batch include IFELSE statements?

syntax:If (condition) (do_something) ELSE (do_something_else)

Example 
SET /A a = 5 
SET /A b = 10
SET /A c = %a% + %b% 
if %c%==15 (echo "The value of variable c is 15") else (echo "Unknown value") 
if %c%==10 (echo "The value of variable c is 10") else (echo "Unknown value")

2. Write a simple Powershell Script with IFELSE statements?

Syntax:

Following is the syntax of an if...else statement −

if(Boolean_expression) {
   // Executes when the Boolean expression is true
}else {
   // Executes when the Boolean expression is false
}

if($x -le 20){
   write-host("This is if statement")
}else {
   write-host("This is else statement")
}

The output ->This is else statement
