getchar() from c to c++ ?

[neoragexxx]

well is there a similar function in c++ ?

instead of getchar() in C i wanna use a similar function for c++ .

and how can i read the buffer from cin .. ?

(i know i can clear it with cin.clear() but i want to read it)

e.g with cin >> number if the user writes more characters after the number.

thanks in advance
