in professor problem-set-4 i write the code completly right and my app runs without any problem but check50 gives an error to my code like: can't check until a frown turns upside down but my app provide all the specifications in pset. i didnt share my code because it makes an spoil to the pset but i can send to any staff member of cs50

this is my code to problem-set-4 professor my app copiles and runs completly ok and it provides all the specifications but i dont know why check50 isnt working ok
