Rules:

• The answer must be stored in a variable of the correct data type given your data.
• The values for your data (A, B, C, D) must be stored in register (e.g. eax, ebx), not variables.
• You must supply the initial values for the data (A, B, C, D).
• Create a string that could accompany the answer in an output statement.
• Comment each line of your code as Demonstrated in Program 3.2 (I know I said not to do this, but for the first assignment it is better is you figure out the usage of every line)

C++ code:

int main()

{

int answer = 0;

// A, B, C, D should be replaced by any number,

// for example A = 1, B = 2, C = 3, D = 4 or any other set of values

answer = (A + B) (C + D);

return 0;

}

How will you know the program is correct?

Take any set of 4 values for example 1, 2, 3, 4 for A, B, C, D. If that is true then the operation (A + B) (C + D) will have to store (1 + 2) (3 + 4) = -4 or FFFFFFFC in hex. Make sure the answer variable is storing that value by debugging your program and directly check the value stored.
