In C, how can i get input (integer) without using ENTER?

Question

I cant use scanf() because to receive integer input you need to press ENTER (when you are running the program).

BTW i need to get from the users 4 digits in the same row like 4563 end then the program should continue without waiting for the user to press enter (if someone got my question wrong i hope that this comment will help) — happymancer, Dec 27 '16 at 13:41

Use curses library and use getch function to read a key without pressing enter. This works on linux and i think you can also use it on windows

Why curses? Could you elaborate? – frostblue Dec 27 '16 at 12:13
It is the only library i know it can do what you want – baliman Dec 27 '16 at 12:15
I did not ask the question, also what's the advantage over `getchar` from stdio? – frostblue Dec 27 '16 at 12:22
@saeleko `getchar`, just like `scanf`, reads from stdin which is line-buffered by default on most terminals. There's no standard function to change this behaviour, but curses is a good choice for its portability. – Quentin Dec 27 '16 at 13:30
@Quentin ah right, I was aware of scanf being buffered, not getchar. Thanks – frostblue Dec 27 '16 at 14:47

If you are in Windows, then use getch() from conio.h If you are in Unix/Linux.. you will probably need some terminal/tty adjustments. Check here:
