You are coding in an obsolete version of C++.

: world.cpp:    In function `int main()':

: Use what first? Whats wrong?

The compiler tells you that the undeclared function/variable is used
first in main(), just in case you would have more functions that also
used that undeclared function/variable.

You should get an up-to-date tutorial or book that teaches standard
C++. If you do you will find you need to add "std::" in front of
"cout".


Right,
