Show a complete C++ code of this instruction which moves in the four basic forms shown below. Include the Rep prefix too. This program should be done in C++

The MOVS Instruction The movs instruction takes four basic forms. Movs moves bytes, words, or double words, movsb moves byte strings, movsw moves word strings, and movsd moves double word strings Con 80386 and later processors). These four instructions use the following syntax: (REP) MOVSB REP) MOVSW tREP) MOVSD Available only on 80386 and later processors (REP) MOVS Dest, Source The (move string, tes) instruction fetches the byte at address ds:si, stores it at address es di, and then increments or decrements the si and di registers by one If the rep prefix is present, the CPU checks cx to see if it contains not, then it moves the byte from es:di and decrements the cx register. This S:si to process repeats until cx becomes zero In this assignment, you will implement the X86 Prefix instruction REP Movs in all forms using any high level language.
