A processor begins with the number 5 in the memory cell 54. In memory cell 55 is an instruction to load the number 0 (zero) into register 2. In memory cell 56 is an instruction to load the contents of memory cell 54 into register 3. In memory cell 57 is an instruction to switch the program counter to 50 if register 2’s value is greater than 0. In memory cell 58 is an instruction to increment register 3 by 1. (i. e. r3’s new value will be r3’s old value+1) In memory cell 59 is an instruction to increment register 2 by 1. (i. e. r2’s new value will be r2’s old value+1) In memory cell 60 is an instruction to load the program counter with the value 57. In memory cell 61 is an instruction to stop the execution.
a. What is the memory address (cell number) of the last instruction that would be executed?
b. When the program starts executing, what value will be stored in register 2?
c. When the program stops executing, what value would be stored in the memory cell 54?
