Title: Newbie header file
Description: to simplify things

I decided to work on a header file that would make things more understandable for people who are new to C++. This one is for consoles. I'll probably make a win32 one too eventually. It is really just a bunch of Macros that make things more readable. I intend to add to it, so if you have any suggestions, fire away.

<EDIT>

I need to overhaul the header. the version the link went to sucked, so I took it down.

CODE

#define ask_for_string(string a, string b) cout<<a; cin<<b;
#define ask_for_integer(string a, int b) cout<<a; cin<<b;

Shouldn't that be

CODE

#define ask_for_string(string a, string b) cout<<a; cin>>b
#define ask_for_integer(string a, int b) cout<<a; cin>>b

I removed the last ; because else you would not need to put a ; behinde the macro evocation.

Also I don't think that macros are a good idea because if you make some code error the compilers says that cout<<a; cin>>b is wrong instead of ask_for_string(string a, string B). But that's just me.

Yeah I realized that macros are not the best idea for some of the functions. I redid some of it and will upload an updated copy soon.

you could use

CODE

#include <iostream.h>
#define print(x, n) cout<<x; if(n!=0) cout<<"\n";
#define input(x, n) cin>>x; if(n!=0) cout<<"\n";

then all you would have to do is put

#include <easycpp.h>

int main()
{
int name;
print("entyer your name", 1);
input(name, 0);
return 0;
}

There are two KeyWords I think you should know about: typedef and inline.

USE INLINES! JUST LOOK AT ONE OF THE ERRORS CAUSED BY YOUR min:

CODE

integer i = 5 + min(2 + 1, 6);

Gets evaluated to:

CODE

integer i = 5 + 2 + 1 < 6 ? 3 : 6;

I think you can see the problem... You can fix it by putting perenthesis around the arguments like this:

CODE

#define min(a, b) ((a)<(b) ? (a) : (b))

But then imagine if you did this even then:

CODE

integer a = 3;
integer i = min(a++, 6);

LOL a ends up being 5, and that's a problem you can't get around. USE INLINES!

The header I have up there now is crap. I'm having problems with my updated version. I'm taking the first one down.

if you can try to make it as much like gml as possible. remember most of our members and future members were/are into gml.

Heh I made a header file like this such a long time ago..psuedo code...brings me back to the good old days...
