Cout library - QtCreator programming question

[hakermania]

Hi, i am (still ) a beginner in C++
I need the library in which i can found the "cout"
The tutorial I follow uses iostrem.h, however Qtcreator gives error "Library not found"
Qt finds the library iostream (without the extension .h)
but cout doesn't seem to be there - it gives error "`cout` was not declared in this scope"

Any help?

cout is part of the c++ standard library, it represents the standard output stream
it is defined in the header iostream. iostream.h is deprecated, this means your tutorial is outdated!
http://www.cplusplus.com/reference/iostream/cout/

it lies in the namespace std as all other standard stuff
so you have to call std::cout or put a using namespace std on top of your source file or a using std::cout in the scope where it is used

hmm all seem to be alright but p, li { white-space: pre-wrap; } endl;
is not recognized as it was with simple cout

I know your mistake.
If you are using QT4c++ and want to develop console appli

cations, you have to create a new Console Project. Thats the only way you can do it.
And you have to execute it on the terminal. I don't why it doesn't works
You have to compile in QT, after that go to terminal. In terminal go to the directory where the project is and do the following commands.

qmake name of the project.pro

the do this one

./name of the project

#include <iostream>
using namespace std;
int main()
{
cout << "blah blah" << endl;
return 0;
}

- or -

#include <iostream>

int main()
{
std::cout << "blah blah" << std::endl;
return 0;
}
