How could I write a loop that prompts the user to enter a temperature value and stores that value in the array?

Does your code work? If no, how? – klutt Mar 28 '21 at 22:25
It doesn't, it asks me to input the first element and then quite – mohammed alsir Mar 28 '21 at 22:26
The compiler should have given you warnings. Did you see any? Also, always check the return value of `scanf`. – kaylum Mar 28 '21 at 22:32
No i didn't see any – mohammed alsir Mar 28 '21 at 22:33

Well, first, I think you mean `i < 7`, not `i <= 7`. – torstenvl Mar 28 '21 at 22:33
What does stepping through the code in the debugger show you? – Ken White Mar 28 '21 at 22:36

Which compiler are you using? This is the warning from gcc: *warning: unknown conversion type character ‘.’ in format [-Wformat=] scanf(" %.1lf\n",&temp[i]);*. The dot is not a valid flag for `scanf`. You may be confusing it with the `printf` precision specifier but that is not valid for `scanf`. – kaylum Mar 28 '21 at 22:38

@kaylum you Nailed it !!!!!!! Thank you so much – mohammed alsir Mar 28 '21 at 22:43
Remove `\n` from the format string – M.M Mar 29 '21 at 00:01
