Write a function that search an item in the array -ubmission (1) data array DWORD 1@h,20h, 30h, 40h, 50h sample DWORD 50h Write a function that search an item in the array The .data section contains two items – "array" and "sample" .code • You have to write a procedure that search "sample" in the "array". If 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.

**Write a Function that Searches an Item in the Array** **Submission (1)** - **Task**: Write a function that searches an item in the array. - **Data Section**: Contains two items—“array” and “sample”. - You have to write a procedure that searches “sample” in the “array”. - **Return Values**: If the item is found, return the item using the EAX register. If not, return -1 using the EAX register. - **Parameters**: Pass the parameters using registers. - **Procedure Steps**: - Push the register arguments at the beginning of the procedure. - Pop them at the end of the procedure. - **Documentation**: Detailed documentation of the procedure is in the next slide. **Code Section Explanation**: - **Data Definition**: ``` .data array DWORD 10h, 20h, 30h, 40h, 50h sample DWORD 50h ``` - **Procedure Comments**: - The procedure is designed to search a given item in a given array. - **Receives**: EBX, ESI, ECX, EDX as input. - **EBX**: Contains the item to search for in the array. - **ESI**: Contains the address of the first item in the array. - **ECX**: Contains the number of items in the array. - **EDX**: Contains the size of each item in the array. - **Returns**: - If item is found, EAX stores the item. - Otherwise, EAX contains -1. - **Requires**: Nothing special. - **Procedure Outline**: ```assembly Search PROC ; implement the procedure ret Search ENDP ``` - **Graphical Elements**: - An inline image displays memory allocation for the `array` and `sample` items in the `.data` section, providing a visual representation of their byte values (10h, 20h, 30h, 40h, 50h for the array; 50h for the sample).
