Question

I get the error error: ‘Name’ was not declared in this scope
What am I missing here.

Source File:

#include<iostream>
#include "scr.h"
using namespace std;

const char* const Test::Name;  

void Test::Print()
{
    cout<<Name;
}

int main()
{       
    Test *t = new Test();
    t->Print();
    delete t;   
}

Header File:

class Test
{   
    static const char* const Name = "Product Name";
    public:
        void Print();
};

EDIT:

If I replace char* const with int, it works. Why?

static const int Name = 4; //in header

const int Test::Name;  //In source

The purpose of the code is to have an alternate for #define as mentioned in Effective C++. In the example there, static const int is used.

Answer 1

You can’t initialize members in class definition.

Take a look at Parashift post – Can I add = initializer; to the declaration of a class-scope static const data member?

SUMMARY: The caveats are that you may do this only with integral or
enumeration types, and that the initializer expression must be an
expression that can be evaluated at compile-time: it must only contain
other constants, possibly combined with built-in operators.
