Question

.MODEL FLAT INCLUDE io.h i header file for input/output STACK 4096 .DATA word1 word 1234 result byte 6 dup(?), e .CODE MainProc PROC wtoa result, word1 exit with return code e mov eax, ret MainProc ENDP END Assume you set a break point in ret statement and look at the memory that starts from the address of result. Write what your expect to see in the next 6 bytes starting from result.

Answer 1

Answer :-

the next 6 bytes :-
52

51

50

49

32

32

Explanation :-

wtoa result, word1 :- actually wtoa converts the 2's complement word number into 6 byte long ASCII converted value of the 2's complement source number and store it in the destination in string fomat

So,

1234 2's complement is 1234

ASCII value of 1234 = 049 050 051 052 (which is of 4 bytes)

In order to convert 4 byte string into 6 byte long by adding leading spaces whose ASCII value is 32.

So, result value :-

032 032 049 050 051 052
