please see question 1.25b in the comp.lang.c faq available at 
http://www.faqs.org/faqs/C-faq/faq/.

the following would do something sorta good enough:

#include <stdio.h>

int main(void) {
    while( getchar() != '5' )
	puts("Guess the magic number:");

    return 0;
}

however, the correct prompt in this case is "Guess the magic character", 
not magic number.

for a simple example of parsing numbers typed on the command line, you can 
take a look at http://unur.com/howto/c-examples.html.

hth.
