Code decoding is the process of retrieving the original sequence of the program from its random-gibberish state, in general, the characters of the code when encoded will be replaced with their ASCII values, or in the advanced state, with special characters, this is all good when the user wants to protect it from code tampering, but when presenting it for a mechanical compilation, it becomes a whole lot difficult for the user or the compiler who is verifying it. So, we decode the code before submitting to ensure the code is converted to a man and machine-readable format to avoid any kind of mishaps.
