2’s Complement of a Number Assembly Language


Write a Program to find the 2’s Complement of number given by the user . Program should load number into register and then find 2’s Complement of Number .

Algorithm behind the 2’s Complement is given below and based on this strategy you can easily implement 2’s Complement program in Assembly Language .

Algorithm for 2’s Complement of Number:


Step I : Initialize the data memory.

Step II : Load the number in AX.

Step III : Find 2’scomplement of number.

Step IV : Display the result.

Step V : Stop.
