Question

Create a procedure named FindLargest that receives two parameters: a pointer to a signed doubleword array, and a count of the array’s length. The procedure must return the value of the largest array member in EAX. Use the PROC directive with a parameter list when declaring the procedure. Preserve all registers (except EAX) that are modified by the procedure. Write a test program in C/C++ that calls FindLargest and passes three different arrays of different lengths. Be sure to include negative values in your arrays. Create a PROTO declaration for FindLargest

MAKE SURE TO USE ASSEMBLY LANGUAGE 32 BIT for the first part including irvien Liberary

Explanation / Answer

Code :

.code
FindLargest PROC,
   array_num: PTR DWORD,
   arraySize: DWORD
  
   mov esi, array_num
   mov ecx, arraySize
   mov eax, [esi]
   dec ecx
scan_array:
   add esi, 4
   mov ebx, [esi]

   cmp ebx, eax
   JLE check_number

   mov eax, ebx

check_number:
   loop scan_array

   ret
FindLargest ENDP
END
