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?

You possibly forgot

#include<string>

And you should call the type std::string.

std::string m ="kosala";

drew , i did like that also but it gives like this error .... error: C2664: 'QLabel::setText' : cannot convert parameter 1 from 'std::string' to 'const QString &' Reason: cannot convert from 'std::string' to 'const QString' No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called – Kosala Jayakody Jul 19 '15 at 01:41
