•Write a function that search an item in the array Submission (1) • Write a function that search an item in the array array DO s, IO s The data section contains two items -"array" and "sample" You have to write a procedure that search "sample" in the "array". • f the item is found return the item using EAX register, otherwise, return -1 using EAX register. You can pass the parameters using registers • Push the register arguments at the beginning of the procedure. And pop them at the end of the procedure. • Detail documentation of the procedure is in the next slide :This Procedure search a given item in a given array : Receives: EBX, ESI, ECX, EDX content as input. EBX contains the item we want to search on the array ESI contains the address of the firat item in the array ECX contains the number of items in the array EDX contains the size of each item in the array : Returna: EAX, If the item found in the array, EAX stores the item we are searching Otherwise, EAX containa -1 : Requires: Nothing Search PROC implement the procedure ret Search ENDP
