[Assembly] Enhance procedure 'printf' to handle escape character '\'. Anything after escape character losses its special meaning if any. For example "\\%s" should print '%s' on terminal instead of refereeing to corresponding string and print the string. Assemble and execute printf_extension.asm. After the above enhancement, the program should run ok. This should create following sample output My string is 'test printf' and integer is 16 My name is John Adams I am 26 year old I love to eat pizza I will graduate in 2015 My name is %s I am %d year old I love to eat %s I will graduate in %d Upload updated printf_extension.asm (do not change the file name). Notes: 1. If you run initial program without any modification, there will and exception error. Once you handle escape character this error should be gone. 2. Make sure to to turn on 'Initialize Program Counter to global main if define' in the MARS editor's 'setting' pull down menu. print_extension.asm cs47_macro.asm: All you need to modify is printf_extension.asm.
