Ah, the confusing specification strikes again. ;-)

In one place, the spec says to prompt for the name. Later it says to write the code so that it "looks like the examples", which don't actually "prompt" for the name. The latter is the correct instruction.

If you remove the printf statement, this main problem will be eliminated. Not saying there are or aren't other issues. ;-)

  • @Ciff B Hi!, thank you for your help, but I'm still lost. Are you talking about the final printf statement just above the return 0; ? And if so, how would that fix it? – phindex Oct 20 '17 at 7:53
  • 'printf("Please enter your name: ");' should be removed. Another lesson: pay close attention to the errors reported by check50. If you look at all the failed tests, you would note that they all said that they were not expecting to see " Please enter your name..." – Cliff B Oct 20 '17 at 8:05
  • Ahh, that's a good point. Thank you! – phindex Oct 20 '17 at 8:41
  • With your help, check50 just passed me green-lit all the way down. Thanks again. – phindex Oct 20 '17 at 8:45
