Thread: [Dev-C++] Error using std::cout

Hello,

I just tried to compile this program and I had an error saying cout not =
declared:


#include <iostream>
#include <stdlib.h>

using std::cout;

class World
{
public:
 World (int i)
 {
  std::cout << "Hello from " << i << ".\n";
 }

 ~World ()
 {
  std::cout << "Good bye.\n";
 }
};

World TheWorld (1);

int main()
{
 World myWorld (2);
 std::cout << "Hello from main!\n";
}

I'll appreciate any help you can give me.

Napoleon.

I just pasted your code into a blank source file on Dev-C++ 4.9.4.0 and 
compiled it without problem. Here's the output:

Hello from 1.
Hello from 2.
Hello from main!
Good bye.
Good bye.

I found no errors, the code is ok. How did you try to compile it?

Hello and thanks,

I don,t know what I'm doing wrong but all I've done is create a console
project with the source code. and when I compile I get the following error
still:

/C++Lab/Temp/test.cpp C:\C++Lab\Temp\C
In constructor `World::World(int)':
10 C:\C++Lab\Temp\test.cpp
`cout' undeclared in namespace `std'

I'm still scratching my head .

Napoleon.

It may be a Dev-C++ bug. Try to create a blank file without any project,
save it as .cpp and compile it.

I just created a new console application project and pasted your code in 
to replace the default code. Still no problems.

I received the clock skew error on the first compile, but the second 
compile proceeded without incident.

Hello Fellas,

Thanks for your help but I think what it's alright now. I unistalled dev-C++
and did a fresh download and installed and it seems to be fine. Thanks for
your help.

Napoleon.
