Why doesn't getchar() wait for me to press enter after scanf()?

Question

I am learning C and I\'m using \"getchar()\" to stop the command windows so I can see the exercises am doing but it just doesn\'t work. heres a sample:

#incl

Your scanf only ate the number but not the trailing newline. Putting a newline or white space after the %d will then give you the opposite problem, reading too far.

This is why people don't like scanf.

I would suggest reading an actual line (use fgets(3)) and then using sscanf() to scan the string.
