<br />
#define ADDLETTER(a) td##a<br />

That's pretty easy:

#define ADDLETTER(a) td##a

<div class="content wysiwyg-content">
I am trying to name the variable using define<br />
example #define ADDLETTER(a) will add letters 'td' to a, and declare this variable with that name. <br />
So, If i declare int ADDLETTER( a); compiler should compile it as int tda; <br />
second example<br />
int ADDLETTER( bc );<br />
the compiler will compile as <br />
int tdbc;<br />
Is this even possible to do?

use #define to name variable

C++ is an intermediate-level general-purpose programming language, not to be confused with C or C#. It was developed as a set of extensions to the C programming language to improve type-safety and add support for automatic resource management, object-orientation, generic programming, and exception handling, among other features.
