Macro File: Create macros to print an int, print a char, print a string, get a string from the user, open file, close file, read file, and allocate heap memory. You can use more macros than these if you like. Main Program File: 1. Allocate 1024 bytes of dynamic memory and save the pointer to the area. 2. The main program is a loop in which you ask the user for a filename. If they enter nothing for the filename, exit the program. Otherwise: a. Open the file for reading. If the file does not exist, print an error message and terminate the program. b. Read the file into an input buffer space of 1024 bytes. c. Close the file. d. Output the original data to the console. e. Call the compression function. Save the size of the compressed data in memory.
