Opening a file

[sirc89]

How do I change the initial part of the program where it doesn't prompt a user to input the path of the text file they want to read, but automatically opens a text file once the code is ran.

I want it to specifically open s:\\windows\gettys.txt

I know I have to use input.open("s:\\windows\gettys.txt"), but when I initially did it, it didn't work.

Please help.

#include <iostream> // for cin, cout and cerr
