void foo(int &x) -> Ruby? Passing integers by reference?
- by Earlz
Hello, as a way to spice up my C++ programming homework, I've decided to instead of typing the C++ from the book onto my computer, instead reforming it in Ruby. Yes it's a bit silly, but I'm bored.
Anyway, I'm having trouble converting this kind of function to Ruby
void swap(int &a,int &b){
int c=b;
b=a;
a=c
}
What would the equivalent ruby code looking inside a function ?
