Below is the function prototype of the function to implement.

void processTheaterInformation$($fstream& fileInput, Theater& myTheater$)$;

Previously, the program read from a file containing theater information. Unlike the previous theater file, the program $3$ theater file will now have indivdual theater screens listing the theater room name, how many parking spots there are and what movie is being shown. Your job is to write a function that takes information from the theater file and processes it into the myTheater structure. The function requirements are listed below:

The function should continue to ask the user for a filename until a valid filename is provided AND the file already exists.

If the user enters "exit" for the filename prompt, it should exit the function early stating $""$Exiting function due to early exiting of file prompt".

The function is responsible for BOTH opening and closing the file stream.

The file will always have the following:

Theater name
