| Macros with Arguments | | 2007-07-18 15:05:00 | | Have a look at the following code:
#include<iostream.h>
#define MAX 10
void main(void)
{
for(int i=1;i<=MAX;i++)
cout<<i<<endl;
}
Above we have used the type of macro expansion that we learnt in the article
Introduction to C++ Preprocessor Directives
Do you know that just like functions we can have arguments in the macros too!
The following code shows how:
#include<iostream.h>
// this is how macros with
// arguments are defined
// NOTE: THERE SHOULD NOT BE
// ANY SPACE BETWEEN THE
// MACRO TEMPLATE (i.e. AREA)
// AND THE PARANTHESIS
// CONTAINING THE ARGUMENTS
// (i.e. (x))
#define AREA(x) (x*x)
void main(void)
{
// calling a macro
// is almost similar
// to calling a function
cout<<AREA(10);
}
It is that simple! However, keep one thing in mind as stated in the comments
not to put any space between the macro template and the braces containing the
argument.

| | Holy Macros! Its LOLcats! | | 2007-05-16 06:00:41 | | Internet culture is invading the family. One morning this week, I woke the kids and told them to get ready for school. Princess: Mmfghaamm... Gothgrrl: I don’t WANT to go to school! Mama: You have no choice. Get up. Princess: But I has a bucket! Mama: (giggle) Gothgrrl: OH No! They be stealing my bucket! They are, of course, referring to one of my favorite image macros. These are also called LOLcats, because the biggest part of them (and some very funny ones) are pictures of cats. Cats PWN An explanation of what LOLcats are. Subgenres include the “invisible” series, and “I’m in Your X, Y’ing Your Z”. Mental Floss also looks at advanced forms. Macros, especially those featuring cats, have developed their own language style and grammar. It’s a combination of Engrish, l33tsp33k, and baby talk.
