We are using the x86 processor, and they all are 32 bit programs. The programming language is Assembly, and we are using visual studio community.

1) Create a definition of each data type listed below. Initialize each variable to a value that is consistent with its data type. Then move each variable into a register and step through your program to make sure that it works. Note: Make sure that your variable sizes match the register sizes. BYTE, SBYTE, WORD, SWORD, DWORD, SDWORD,REAL4 Variables are in memory. To see them, while paused in debug mode, add a Memory window to your view. You can type on addresses to find values. To find a variable by name, use & in front of it. (e.g. for a variable named bVar, use &bVar).

2) Declare an array of 60 uninitialized unsigned doubleword values. Create another array of 60 unsigned doublewords, initialized to abcd. Look at these arrays in the memory window and note how they are stored. (Intel architecture uses little - endian order).

3) Create a DWORD variable in which the hexadecimal data would be stored internally as 12345678.

4) Define a symbol for your name as a null-terminated string.

5) Write a sequence of MOV instructions that will exchange the upper and lower words in a doubleword variable named three.This is some of the code I have done.
