Why do I get an error undefined reference to `getche'?

Question

I'm using clang-7 on 16.04.1-Ubuntu LTS. I get this warning:

warning: implicit declaration of function 'getche' is invalid in C99 
[-Wimplicit-function-declaration]

followed by this error:

error: undefined reference to 'getche'`

What could be wrong?

Here is the link to my code:

`getche` is not a standard function I'm aware of , and you don't define it yourself. what function did you want to call? — erik258, Apr 25 '20 at 15:15
`getche` is a Microsoft-specific function which doesn't exist in your compilation environment. — rici, Apr 25 '20 at 15:16
```getche()``` to get a single character entered by the user @DanielFarrell — Kally, Apr 25 '20 at 15:16
It is an extension in Windows MSVC requiring `#include ` but MS also deprecate it in favour of `_getche()` to follow the Standard C rules for implementation-specific names. However, the function is still supported. — Weather Vane, Apr 25 '20 at 15:17

getche() is <conio.h> library, therefore it's Windows specific, for alternatives you can look at What is the equivalent to getch() & getche() in Linux?
