How to use standard C++ code with Qt code in the same program?

Question

string m ="kosala";
ui->label_5->setText(m);

This gives me :

string is undeclared identifier

I want to use string data type as in here without QString type. How can i do that?

Answer 1

You possibly forgot

#include<string>

And you should call the type std::string.

std::string m ="kosala";
