Question

For 6-7, convert the C code to equivalent MARIE code. You may reference literal values using an immediate datum mode as in #1, or assume the value is in a variable of the same name (e.g., one).

6) scanf(“%d”, &x);

z=0;

for(i=0;i<x;i++)

                scanf(“%d”, &y);

if(y==0) z++;

                }

                printf(“%d”, z);

Answer 1

Below is the solution in Marie. You can go through the solution for this I am considering ORG as 100.Read the comments for your better understanding.

SOLUTION

ORG 100
Input //Taking input
Store x //Initializing x
Load x   
Load z //Loading the stored variable z=0

Top(Loop), Load i //Loading Loopconstant
Subt x //Checking condition in loop i<x
Skipcond 800 //if i<x it will stop loop
Jump LoopEnd //quit the loop
Input //Taking input
Store y //Initializing y
if, Load y   
y EQ #0 //Checking if(y==0)
Load    z
    Add One //z = z+1
   Jump Top
EndLoop, Halt //Loop End
Load z
Output //Printing z

z, Dec 0 //Storing z =0 initially
i, Dec 0 //Storing i =0 initially
