Please Modify this code according to this instructions

cmds.c

– Need to modify the Cmd struct to include:

“ms” and “h”

– Add code in mem_display(), help(), mem_set() functions

– Command routine calls with 2 arguments, e.g.

• mem_display(Cmd *cp, char *arguments)

&cmds[0]

Address of the string “10000”

– If we enter a command “md 10000” to display the contents of 16 locations starting with 10000, the arguments passed are:
