Internal and External Linkage

Internal and External Linkage

Global inline functions, consts and typedefs have internal linkage.
That means that the declarations in these two files do not interfere with each other:

 	//File1.c	typedef int T;	const int a = 12;	inline T f (int i)	{ return i+a; }	//File2.c	typedef void T;	const int a = 8;				inline T f (double d)	{ cout  

size=3>
A const can be given external linkage by an explicit declaration:

 	//File3.c					extern const int a;			const int a = 77;	//File4.c	extern const int a;	void g () { cout
