Question

Please provide x86 (MASM not NASM) .386 (32bit) assembly program for the following (needs to be compatible with Visual Studio 2015.asm file):

(10 points) Write an assembly program to find the largest element by searching an array int aryll-[11, 15,-3,-4, 0,60.11,-9,18) int index-l; int max- 0; int arraySize-sizeof array /sizeof max while (index < arraySize) if (ary[index] > max) max = ary[index]; - Use cmp instruction and the appropriate jump instruction (signed or unsigned) to translate the if and while statements Use S operator (see chapter 3) to calculate the size of the array, and inc instruction to increment the index of the array Run your program using the debugger to verify your answers (do this too for questions 2) Maximum value should be in max variable at the end. -Submit the following: o Lastname1.asm

Answer 1

X86 program :-
