Question

Assignment 3B: Adding 4 32-Bit Integer Variables

The program will contain four 32-bit integer variables and add these values together, saving the result in a variable. The sum should still be in the EAX register when you call the library routine DumpRegs.

Have your values initialized in the data segment.
