My program is showing all the outputs correct but yet Solo Learn is showing it as Incorrect. Can anyone explain?

Question

I made a raw program of "Military Time" and i know it's too bad to show but surprisingly it's producing correct output. But Solo Learn app is showing it incorrect.

Answer 1

Regarding the seemingly correct output: Whenever your solutions appear correct but are not approved, it is usually because you print characters without a console representation somewhere.
For example, in your program both paths lead to the string containing a null character, which is not visible on the console, but nonetheless in the output buffer. As a consequence, the string comparison between the given solution and your own will fail due to that extra character in the buffer.

Answer 3

Thanks for the help buddy Galaxy-Coding. But could you just explain what is actually happening with the program I made I mean it's showing the correct output, right?
What's the problem, then?

Thanks for the information Shadow. 🤝

By the way, few hours back, I figured out the solution. I just displayed the string using using a loop and it worked.
