How can I make comments/descriptions in MQL4 code?

Question

In python and other languages, you can write a multiline description like this:

def func():
   '''
   this is my function description
   '''
   pass

How do you do this in MQL4?

Answer 1

You use two forward slashes, for example

void function()
{
   // Description
}

If you want to use multi-line descriptions, you can block out portions of code, for example

void function()
{
   /*
   Description line 1
   Description line 2
   */
}
