else keyword in Julia

Keywords in Julia are reserved words that have a specific meaning and operation to the compiler. These keywords can not be used as a variable name, doing the same will stop the execution process and an error will be raised.

‘else’ keyword in Julia is used to execute a block of code when the ‘if’ condition is false. If the condition is true, the code after the if statement will be executed otherwise the body of else statement will be executed.
Syntax:

if condition
    statement
else
    statement
end

Flowchart:

Example:

Output:

5 is smaller than 10
This is not in if

'else' keyword can also be used with 'if' keyword to generate an ‘if-elseif-else’ ladder.

Example:

# Julia program to illustrate
# if-elseif-else ladder
i = 20
if (i == 10)
    println("Value of i is 10")
elseif(i == 15)
    println("Value of i is 15")
elseif(i == 20)
    println("Value of i is 20")
else
    println("Value of i is not defined")
end

Output:

Value of i is 20
