Debugger perspective : How to show a variable content as it prints using << ? [message #1818837]

Hi All,

I have been working with C/C++ CDT for a while now and I love it.

In Debugger Perspective, I just need to be able to see the custom class objects representations in the Variable subwindow as if they are printed in the console using the << operator.

Please let me know I could do that ....

Regards,

int TEST = 10;
cout << " TEST " << dec << TEST << endl;

You could write it to a string stream and view the buffer.

Be aware that viewing the content of a string stream isn't easy.
You could do this instead:

#include <iostream>
#include <sstream>
using namespace std;

std::stringstream ss;
int main() {
	cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!
	ss << 100 << ' ' << 200;
	std::string txt = ss.str();
	cout << txt << endl;
	return 0;
}

You can also typecast and change the display base of variables by right-clcking on them in the Variables view.
