I'm trying to create a static member in a class so I do not need to instantiate the class to get the value of the class.

In the examples I found on the internet, it references members int .

In my case I want the static member to be a string .

If I do the following:

class algumacoisa
{

public:
 algumacoisa();
~algumacoisa();

string texto;
static string recebetexto;

};

texto = "alguma frase aqui...";
string algumacoisa::recebetexto = texto;

The following error message appears:

error: qualified-id in declaration before '=' token

It is just to illustrate that if you assign a normal string variable to a static string variable, the described error occurs. The code is not complete, but you can get an idea of what it refers to.

Examples made anyway can have all sorts of problems. I did it right and it does not have any problems.

#include <iostream>
using namespace std;

class AlgumaClasse {

public:
    static string recebetexto;
};

string AlgumaClasse::recebetexto = "alguma frase aqui...";

int main() {
    cout << AlgumaClasse::recebetexto;
    return 0;
}
