hello, i have been working on a code for a program which displays the number of counts on an LCD display. When count = 0 it should display Parking Full. When i compiled the code it says invalid expression. I used conversion to string before that but it did not work, so i wrote my code without string conversions.
Can anyone check and suggest why it is not compiling? Here my full code:
