Julia end Keyword | Marking end of blocks in Julia

Keywords in Julia are reserved words that have a pre-defined meaning to the compiler. These keywords can’t be used as a variable name.

'end' keyword in Julia is used to mark the end of a block of statements. This block can be of any type like struct, loop, conditional statement, module, etc.

Syntax:

block_type block_name
    Statement
    Statement
end

Example:

# Julia program to illustrate
# the use of 'end' keyword

# Defining a function
function fn()

    # Defining for-loop
    for i in 1:5

        # Using if-else block
        if i % 2 == 0
            println(i, " is even");
        else
            println(i, " is odd");

        # Marking end of if-else
        end

    # Marking end of for-loop
    end

# Marking end of function
end

# Function call
fn()

Output:

1 is odd
2 is even
3 is odd
4 is even
5 is odd

Note: 'end' can also be used to mark the last index in a 1D array.

Example:

# Julia program to illustrate
# the use of 'end' keyword

# Defining Array
Array1 = Array([1, 2, 3, 4, 5])

# Printing last element using 'end' keyword
println("Last element of Array: ", Array1[end])

Output:

Last element of Array: 5
