Printing var name

[Cernunnos]

So, I wanna print my var name as well as her value, since generic programming is DATHING I'd love to get a solution to my problem, actually this is what I have:

 #define PrintVar(varName) printf("%s vale %p\n", #varName, varName)

Will work with int, but will print the address for anything else, any idea ?

Well "%p" is for printing a pointer...
so i think you have to create a class for that maybe..

something like this :

class Var 
{
 public: 
 void Printfloat(float var);
{
 printf("%0.2f \n" , var);
}
 void PrintInteger(int var)
{
  printf("%d \n", var);
}
// etc...
    void PrintString();
    void Printchar();
};

then

int main()
{
Var *PrintVar = new Var();
PrintVar->Printfloat(73.37f);
return 0;
}

I used a pointer so I could try playing with the void :3 If I need to if/else then:

#define PrintVar(varName, type) printf("%s vale ", #varName);\
	if (type == "f") printf("%f\n", varName);\
	else if (type == "d") printf("%d\n", varName);\
	else if (type == "c") printf("%c\n", varName);\
	else if (type == "s") printf("%s\n", varName);\
	else if (type == "l") printf("%llu", varName);

,also forgot to say I'm on pure C, not C++.
On C++ it's a way easier:

 #define PrintVar(varName) cout << #varName << " vale " << varName << endl;

Thanks for the help anyways.
Still open to suggestions.

Hmmmmmmmmmm, i don't quite understand what your problem is...

EDIT: ah! i see, you wanted to print the actual variable's name. hold on il edit my post later.

Why do you stick to C?

I think he is coding in Linux...



BTW i forgot to edit my post, i tested your code in VC++ 2013 works perfectly, i retried in Code::Blocks Lubuntu and it worked aswell (C++)
tried building a .C code manually with gedit and and it didn't work , but it works with C++ (gcc) ._.

Gonna try find a way eventually, and oh, can't use typeof/sizeof (before someone suggest) :3

You mean g++ with gcc right ?. And what code did you test, C++ or C one ?

both of them, the code compiled in C++ worked, but the C code didn't work well, must be some compiler bug?
