Assuming the variables are declared as .int, write assembly language instruction

Question

Assuming the variables are declared as .int, write assembly language instructions to implement the following C statement: x-y=1; Only a single assembly statement should be entered for each fill- in-the-blank answer. A fill-in-the-blank answer can be left blank if an assembly statement is not needed, but you will need to write in the word blank. Please use all lower case characters in your answers and single spaces to separate items, other than commas, on each line. If a register is needed, please use one of the eax, ax or al registers.

Explanation / Answer

1. Declare and initialize variable y

y dw 1

2. Use a register to copy the value of y in it

3. Initialize x with al
