a kind of template (or macro) to reuse parts of code...

Show all headers | View raw

Can this be done (and how) in C++ in the following pseudo-code form:

DEFINE_I_TO_1
{
int i=1;
}

int increaseby1()
{
DEFINE_I_TO_1
return i+1;
}

int increaseby2()
{
DEFINE_I_TO_1
return i+2;
}

In other words - I would like to keep all the scopes, definitions etc and 
just to insert a reusable piece of code - much like copy-pasting a block of 
template code.

Of course, I could put it in a function, but I would like to know also if 
there is a way to do it this way because in certain uses this would make 
sense - like loops where timing is critical putting inline code would 
obviously be faster way than calling a function.

I know C++ has macros and templates but from what I've seen they are not 
intended to be used like this. Or am I wrong?

Is this possible and what is the easiest way to achieve this if possible?
