Because the console (stdin/stdout) is line-oriented.  You have to
enter a whole line, and then your program processes it.  You have to
print a whole line before it's printed.  Try using fflush(stdout) for
the second problem; for the first you should use fgets() or one of the
console-specific functions like getkey().

Besides, if you don't press a non-numerical character, how does your
program know that you're done typing in the number?
