Can you define something to be used ANYWHERE in the code?
For example:
#define start {
#define end }
Then do something along the lines of:
if (a < b)
start
code...
end
Would that work? It's probably not a good idea, I'm just curious where you can use defines like that.
Well, it works for me...
Wow... I didn't know it...Code:#include <stdio.h> #include <stdlib.h> #define start { #define end } int main(void) start printf("hello world\n"); system("PAUSE"); return 0; end
Code:#include <stdio.h> typedef int This; #define makes main() #define read return 0; #define code { #define though } #define hard printf("Hi there!\n"); #define to printf("How are you doing?\n"); This makes code hard to read though

It's really ugly...
#define is just a text editor. Before the code is compiled, the compiler just runs through and changes anything of that name to the text provided above. You can define anything and use it in the code.
>#define is just a text editor.
The #define is used by the preprocessor, which runs before the compiler runs. The preprocessor replaces things defined by #define. There are more such things, they are called preprocessor directives.
Use such #define's only when necessary. For example for defining a macro or a constant.
But if you did, say:
would the "start" in that string be replaced by a {?Code:puts("Press any key to start");
Or does the preprocessor not replace inside strings?
I know it's not a good idea to define things like that, I was just curious how and where you can use defines.

It doesn't replace stuff inside strings.
