getchar()

hey everyone!
got another problem here.
how would i use the getchar() in a prompt:
Press any key to continue

the way i did it was to define a char variable named ch
and then wrote

Code:

char ch
...
ch = getchar();
printf("Press any key to continue");
getchar():

if you press enter it exits, but if you type anything else it displays it on the screen and you still have to press enter after.

is there anyway to make the program continue without displaying the result to the screen and so the user can press any key they want?

thanks
