problem with <iostream>

[wesley]

Hi All. i am new to C++. I know that in order to use cout, i need to
include <iostream>. I have done this, but i still get errors when i try
to output to the screen. Is there a file that needs to reside in the
same folder as the project? I know that in java, this is the case.
Please help.
Thank Wesley

I don't think so.

What kind of errors are you seeing ?
I would think that these are compilation errors.

Try starting with the following program:
#include <iostream>
#include <string>
using namespace std;
int main()
{
cout << "Hello" << endl;
string s;
getline( cin, s); // read some user input
return 0;
}

My guess is that you forgot the namespace, remember that you have to
call cout by:

std::cout << "chocolate" << std::endl;

If you dont want to use 'std::' all the time, read this:

std::cout << "Hello World!" << std::endl;

or

using namespace std;

void writescreen(void) {
cout << "Hello World!" << endl;
}

When using cout the text will be flushed to screen whenever there is a
std::endl or when you call flush.

You might wanna take a look at http://www.cplusplus.com/ref/iostream/

Your program works, i tried something similar, but it did not work, I
left out the #include <string>. The include and cout were underlined by
eclipse. Thanks for your help
