  10 pth) CS 3843 Computer orpaniwioa li w Namcabe23. Due Wed Jul 261th, 2017 1. (5 pts) Implement the memmove instruction as discussed in class and verify that it works- the code is below. Also note that I have set up the stack to test the various scenarios memmove is supposed to encounter. This memmove copies one byte at a time 2. (5 pts) Enhance the memmove as described in class such that it will copy 4 bytes at a time and then finish off the remaining 1,2, or 3 bytes as needed. memmove void "destination, void source, int nCount) As sume edi = destination address, esi = source address and ecx = nCount Deliverables: Hard copy of the modified source code WITH COMMENTS on the student source code, and a screenshot of the output of your program running. Make sure to show 6 cases: Each of the ones below before code modification and each below after modification 1. Destination and Source do not overlap 2. Destination address Source address with overlap. 3. Destination address > Source address with overlap. Source Code on next two pages and included as "Inline.cpp" file also
