Given: Assembly code. To find array values after execution.To get the array values, Let's go through the code: main PROCmove eax,10mov esi,0call proc_1 Here, in line 2 address of 10 is moved to register eax. so, eax=10.In Line 3, the address of 0 is moved to esi, esi=0.After this we call proc_1.In proc_1, proc_2 is called. Further, in return proc_2 calls proc_3. proc_3 PROCmov array[esi],eaxIn the above line,proc_3 assigns address pf eax to array[0].This imply that array[0]=10.and, returns value to proc_2. proc_2 PROCcall proc_3add esi,4add eax,3move array[esi],eaxret In proc_2, first, add 0 and 4 and assign them to esi. therefore, esi=0.then, add 10 and 10 and assign them to eax. so, now eax becomes 20.Then, eax value 20 is moved into the array[4].ret will return to proc_1. In proc_1, as of now, we have this data:esi=4eax=20array[0]=10array[4]=20 So, add esi,4 that is, now esi+4=4+4=8add eax,10 that is, now eax+10=20+10=30mov array[esi],eax states, array[8]=30ret tells return to main. In the main after call proc_1, we have data:esi=8eax=30array[0]=10array[4]=20array[8]=30 Now,add esi,4 gives: esi+4=8+4=12add eax,10 gives: eax+10=30+10=40mov array[esi],esx(40 is assigend array to array[12]) Invoking exit process we exit and values of array will now be:array[0]=10array[4]=20array[8]=30array[12]=40

Description Create an application that maintains an array of your home inventory and displays the contents of the array in a list box. For this assignment, we will be using an array. In later chapters, we will modify this application to use a database or an external text file. The application should look like: g My Home Inventory Home Inventory Item Description Ist Homelnventory Serial Number Cost ADD DELETE REFRESH BYE Detailed Instructions 1. Define arrays for Item Description, Serial Number, and Cost after the Public Form Q and before any click of page load events. 2. In the Page Load Event, populate the Home Inventory List Box with the data from the arrays using the format: "ItemDecription (SerialNumber, Cost)". 3. If the ADD button is clicked, add the Item Description, Serial Number, and Cost to the Home Inventory List Box and to the appropriate arrays. 4. If the DELETE button is clicked, remove the item from the Home Inventory List Box and corresponding arrays. 5. If the REFRESH…
The logic will allow the user to: Load a single dimensional array of size 50 with a random number The random number will range from 1 to 1,000 (you may have duplicate values) Find the highest value and the index location that it was in Find the smallest value and the index location that it was in Display the array’s contents. Display the highest value and its index location Display the lowest value and its index location Allow the user to execute this application multiple times (some sort of loop?) You will need one for loop to load the array as well as one or two for loops to search that array. The rand also has a “nasty” tendency to create the same results repeatedly in an exe. To avoid that, we have to “shuffle the deck” every time. This ensures that all numbers are an equal probability of appearing and not the same set of values (would create a boring game). // Add this to "shuffle the deck" every time to ensure that // different values could occur else the exe produces the…
