how do you write a function called readnum?

Question

need to know how do you write a readnum function

Answer 1

You havn't given enough information. A function needs to do something! Here's a readnum function that returns a num from a string (in C/C++, because you called it a "function"):

int readnum(string str) {
return Int32.Parse(str);
}

Answer 2

first off, in what language??? you just need to name it readnum or do you want it to do somethin specific? :P

javascript:

function readnum(){
}

vb:

private/public function readnum as
end function

etc..

Cheers
