What are the alternatives to getch() in C?

Question

C++ / C#

The conio library was not found, but it contained getch()
Installing the library is not an option, because on other computers the program will not get confused because this library is not there, like on most computers.

We need an alternative to getch (), that is, that the function would take a value, and after starting the program, it would not be necessary to press Enter after the entered value

Answer 1

man ncurses
