Using the MARIE computer assembly language, write a program that computes the following expression:z = a * b * c. The computer will read in the input values a, b, and c from the keyboard and the final result(z) have to be displayed. In addition, every time an input value is read in, it must be displayed on the screen.Remember that the instruction set does not have an instruction to execute multiplication.Note: If any of the input values a, b, and c is a negative numbers or a zero, then the result printedshould be “0”. Otherwise, the result of the multiplication must be printed. The program must be tested on MARIE simulator.
Write a program that contains two instructions: (1) add the number 5 to the EAXregister, and (2) add 5 to the EDX register. Generate a listing file and examine themachine code generated by the assembler. What differences, if any, did you findbetween the two instructions?
