Re: [Dev-C++] What's the difference?

[<st...@xs...>]

This really depends on what you're doing.  The main benefit to pointers is that 
you can send them to functions where the function can modify the value of that 
pointer variable.  With normal variables they only get passed by value and 
since you can only have one return value per function it sometimes becomes 
necessary to modify the variables within your function rather than calling the 
funtion multiple times or writing multiple functions that return slightly 
different variables.
