Problem with Plato (C++)

I have tried to run some beginners C++ programs with Plato (latest build). All tests ran successfully with Visual C++ Express 2010. However, when I run the programs employing Plato, I get always only one line of output. For instance

 #include <iostream.h>

 int main()
 {
    cout << 'Hello World!\\n';
    cout << 'Hello World!\\n';
    cout << 'Hello World!\\n';
    cout << 'Hello World!\\n';
    cout << 'Hello World!\\n';
    return 0;
 }

gives (only one Hello World!):

Hello World!

Press RETURN to close window ...

Can anybody help? Many thanks,

Klaus

It looks like it is outputting all the lines, just they are on top of each other.

In Windows you may need to use the following to ensure a 'LF' linefeed is output as well as a 'CR' carriage return.

cout << 'Hello World!\r\n';

or use the following, which is better.

cout << 'Hello World!' << endl;

This looks to me like a bug in the ostream library (within salflibc.dll). A fail flag is being set after the endl and this causes subsequent output to be lost.

I am working on a fix.

I have fixed this bug in salflibc.dll for the next release.

Thank you very much, Paul.
