c++ - Switch cases and getch() don't work together

Question

I've done a pretty simple switch where if I press a character, the integer of it adds one to itself and prints a message, it worked pretty fine with the "cin>>" and the "getchar()", but when I added the getch, It still prints the message but it stops updating the integer "how I know"? cause I made a random value that the integer has to get to, and it's between 1 and 20, and with the getch it simply goes on without stopping itself when arrived to the value
