Question

Write a MARIE program that implements the following logic.

If X < Y

Then

X = X + Y

Else

Y = 2X

Assume the two numbers are X and Y and are entered by the user. Provide prompts to the user to enter the numbers and provide a meaningful output to the screen.

Answer 1

Answer)

Program:

// Read value of X from user
Input

// Store the value of X
Store X

// Read the value of Y from the user
Input

// Store the value of Y
Store Y

// load X to accumulator(AC)
Load X

// subtracted Y from X
Subt Y

// if the AC is negative skip the next instruction
Skipcond 00

// if the AC is positive jump to else
Jump else

// load X to accumulator(AC)
Load X

// Add Y and content in AC (X + Y)
Add Y

// Store the result in X
Store X

// load X to accumulator(AC)
Load X

// jump to done
Jump done

// load X to accumulator(AC) 
else, Load X

// Add X and content in AC (2X)
Add X

// Store the result in Y
Store Y

// load Y to accumulator(AC)
Load Y

// Output  the content in AC
done, Output

// END
Halt

// Define X as a decimal and assign 0
X,DEC 0

// Define Y as a decimal and assign 0
Y,DEC 0
