I have a problem with credit.c.

The program works when the user enter a numeric input but when someone enters a string, i don't know how to make that the program print "Number: " again. Instead of it the program print to the screen "Retry: " as a side effect of the function get_long_long() of the CS50.h

Thanks.

if you use get_long_long("Number: "); it will repeat that prompt if the user doesn't enter a number. if you use get_long_long(); it will print "Retry". check50 is assuming that you are using the first method.
