You need to list header file names, not just the preprossor command include.

You may need to include a statement regarding namespace std depending on your compiler.

main() should always have return type int, not void.

I've never tried to output a string literal equal to this: "&". If that's line 9, then you may have to precede the & by a \ to get it to show.

Posting your error messages indicating a problem on lines 9 and 11 would be helpful.

Next time enclose your posted code in code tags, please. There are a number of excellent posters who won't even consider looking at your code if not formatted correctly for this board.

My two headers are

#include<stdio.h>
#include<stdlib.h>

Cpp1.cpp(9) : error C2679: binary '>>' : no operator defined which takes a right-hand operand of type 'class ostream &(__cdecl *)(class ostream &)' (or there is no acceptable conversion)
Cpp1.cpp(11) : error C2679: binary '>>' : no operator defined which takes a right-hand operand of type 'class ostream &(__cdecl *)(class ostream &)' (or there is no acceptable conversion)
Error executing cl.exe.

tks for helping

You don't use endl; after cin you use it after cout . cin is used for input. Please use code tags as well

Look at the errors you are getting. They concern the operators << and >> and then read the text after them...ostream. As someone else stated, you are also missing a namespace, or at least the specific portions of the namespace that you need.
