For a start, conio.h is not standard C or C++ - it tends to be found in code written for the Turbo C/C++ products, a particular favourite of Indian universities.

And they invariably use it just so they can call getch when there's a perfectly adequate getchar in the standard :-)

As to the index variable, it's probably already defined in one of the headers.

  • Line 18: error: conio.h: No such file or directory:

Try to include <conio.h> instead of "conio.h".

  • Line 25: error: 'unsigned int index' redeclared as different kind of symbol:

It could be that one of the headers you're including already declares index. Try to rename it to see the difference - or better yet don't use a global variable at all.
