Julia: comments

Comments in Julia, makes the program more readable.

Suppose you written thousand lines of program, with out proper documentation, after some time, for the developer of the application also, it is very difficult to figure out what was written.

By using comments, you can document your code at the time of writing program. Comments don't affect your program execution. 

Julia supports two types of comments.

a.   Single line comments

b.   Multi line comments

a. Single line comments

Single line comments starts with # symbol.

b. Multi line comment

Multi line comments enclosed in between #= and =#

hello.jl

println("10+20= ",10+20)
println("10-20= ",10-20)
println("10*20= ",10*20)
println("10/20= ",10/20)
println("10%20= ",10%20)

$ julia hello.jl 
10+20= 30
10-20= -10
