Assembly Language For this program you will call a procedure

Assembly Language:

For this program you will call a procedure that finds the minimum and maximum elements of an array, and the last positions in the array where the minimum and maximum element occurs.

The output of the program is:

The position in array of last occurrence of minimum element is: 4

The minimum element in the array is: 5

The position in array of last occurrence of maximum element is: 6

The maximum element in the array is: 90

Use an array named Array to contain the elements (as DWORDS):

5, 46, 90, 50, 5, 6, 90, 8, 20

All variables in main are DWORDS.

The name of the procedure is MinandMax, and its equivalent call in C++ would be:

MinandMax(int &max, int &maxposn, int &min, int &maxposn,int& Array, int Arrsze);

All arguments must be passed on the stack. You must use the C++ calling conventions for ordering of arguments on the stack. You must use the conventions for caller and callee saved registers on slide 26 of SS7 assuming that all registers EAX, EBX, ECX, EDX, EDI, ESI may be used for some purpose in main other than support for calling MinandMax.

Registers EAX, EBX, ECX, EDX, EDI, ESI are used for some purpose in MinandMax.

In MinandMax, there is only one loop. Thus, you must use conditionals within the loop to implement finding the maximum element, minimum element, position of the maximum element and position of the minimum element.

The ebp register must be saved within MinandMax.

The caller is responsible for cleaning up the stack.

The last line in the program should be END main

Solution

Answer:

.zero 1
.LC0:
.string \"\ \ \\t ENTER THE SIZE OF THE ARRAY\\342\\200\\246:\"
.LC1:
