Question 1.

a. Declare a 32-bit signed integer variable and initialize it with the smallestpossible negative decimal value.

b. Declare an uninitialized array of 100 16-bit unsigned integers.

c. Declare a string variable containing the word DVCrepeated 20 times, and terminated with the null char.

Assignment 3A - A program that adds and subtracts 32-bit numbers After installing the assembler on the computer, enter the following program, save it, assemble it and run it. Do not forget to add a comment with your name in it You will hand in a listing (e.g., addsum.asm) that should include your name TITLE Add and Subtract (AddSum.asm) This program adds and subtracts 32-bit integers Caterina Pentcheva INCLUDE Irvine32.inc code main PROC eax, 10000h 40000h ; EAX=10000h ; EAX=50000h eax, 20000h EA30000h mov add eax, call exit END main DumpRegs display registers main ENDP 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
