Julia function keyword | Create user-defined functions in Julia
Keywords are the reserved words in Julia which have a predefined meaning to the compiler. These keywords are used to reduce the number of lines in code. Keywords in Julia can’t be used as variable names.
'function'
keyword is used to create user-defined functions in Julia. These functions are reusable codes that can be called from anywhere in the code with the name assigned to the function.
Syntax:
function function_name Statement Statement end
Note: 'end'
keyword is used to mark the ending of a function. Everything between the function keyword and end keyword is considered to be the body of the function.
Example:
# Julia program to illustrate # the use of 'function' keyword # Defining a function function func() println( "this is a function" ) end # Function call func() |
Output:
this is a function
Creating Functions with arguments
Functions in Julia also accept arguments. These functions are also created in the same way by using the 'function'
keyword.
Syntax:
function function_name(argument1, argument2, ...) statement statement end
Example:
# Defining a function with arguments function add_fn(x, y) println(x + y) end # Calling defined function add_fn( 10 , 8 ) |
Output:
18
