Use tool 'MARS' to Solve the problem:Download printf_extension. asm in a directory. Default run of this will have error. Copy your cs47_macro. asm in the same directory. 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 outputMy string is 'test printf' and integer is 16My name is John AdamsI am 26 year oldI love to eat pizzaI will graduate in 2015My name is %sI am %d year oldI love to eat %sI will graduate in %dNotes: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.
