Two functions are defined:
compile_brainfuck: This function takes two arguments. The path to the Brainfuck source file and the path where the executable should be placed after compilation. It reads the Brainfuck code from the source file, generates equivalent C code using generate_c_code function, writes the C code to a temporary file, compiles it using gcc, and removes the temporary C file afterward.
generate_c_code: This function takes the Brainfuck code as input and generates equivalent C code. It translates each Brainfuck instruction to its C equivalent.
The script then checks if it’s being run directly (not imported as a module) using if name == “main”:.
It prompts the user to enter the path to the Brainfuck source file and the directory where they want the executable to be placed.
It extracts the filename from the source file path and combines it with the output directory to get the full path for the output file.
Finally, it calls compile_brainfuck function with the source file path and the output file path as arguments, initiating the compilation process.
