(Memory Management): Write a program to simulate Memory Management for First-Fit.
- Define 10 element array and mark as 0 (0 means free memory)
- Repeat the following steps until exit
- Display a menu to ask user to create, delete, or exit
For creation:
- Assign a process number (staring 1 and increase by 1 for each creation)
- Generate a random number between 1 and 4 (means the memory needed by this process)
- Assign the process number to required memory location by using First-Fit (means that memory location used by that process)
- Display the contents of the array
For deletion:
- Ask user to input process number
- If the process exists, delete the memory by assign 0 to those location and display the contents of the array
- If the process does not exist, display error message.
- Write program in java

- Trace these print statements using the following arrays. Write "error", if an error occurs.In Assembly 1. Write code that traverses (or goes through) the following array using the ESI register: .dataarrayOfWords 1020h, 3040h, 5060h, 7080h, 9090h 2. Write code that again, traverses the array in Question #1, but this time using a loop. 3. Using the same array in Question #1, access the 3rd element in the array (the one with subscript 2)4. Declare a variable that works as a pointer to BYTEs.- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only) write a c++ program named "isTheLastNumberTheMax" that accepts an array of integers and its size. It will return true if the last number in the array is the maximum number in that array and false otherwise. In addition, it also returns another boolean to indicate whether this list contains more than one maximum value.For example, if this is called with the array of {10, 20, 30, 40, 50}, it will return true and falseIf this is called with the array of {50, 10, 20, 30, 40, 50}, it will return true and true.
- Finish the swap function below using pointers and write the call to swap in the reverse function using the address of the array positions array[i] and array[size-i-1].using pointers. DON'T FORGET TO DECLARE THE PARAMETERS in the function. (Hint: if you can't figure it out with pointers, do it with the references #include <iostream>using namespace std; // Function to swap two ints using pointers// @param pointer to an int// @param pointer to an intvoid swap( ) {// TODO: Add code that swaps two integers using pointers } // Function to reverse arrayvoid reverse(int a[], int size) {for (int i = 0; i < size/2; i++) {// TODO: write the call to swap in the reverse function using the // address of the array positions array[i] and array[size-i-1].- in this exercise, please do not include and use string class. The function is using only array notation and manipulation.- string functions such as strlen is not allowed.- it should not have multiple return statements in the same function- there should be no global variable.- the function should not traverse the arrays more than once (e.g. looping through the array once only) A C++ PROGRAM named "changeCase" that takes an array of characters terminating by NULL character (C-string) and a boolean flag of toUpper. If the toUpper flag is true, it will go through the array and convert all lowercase characters to uppercase. Otherwise, it will convert all uppercase to lowercase. For example, if the array is {'H', 'e', 'l', 'l', 'o', '\0'} and the flag is true, then the array will become{'H', 'E', 'L', 'L', 'O', '\0'}. And if the flag is false, the array will become{'h', 'e', 'l', 'l', 'o', '\0'}The following is the difference between void and NULL pointers: Use relevant examples to back up your statement.

PART 1Read the contents of the text file and store them in a C++ data structure called std::map<string, int>This map is a collection of sorted <key, value> pairsIn this case, the keys are unique words found in the text file, and the values represent the number of times each word appearsFor example, since the word "cat" appears twice in the file, then map["cat"] = 2 PART 2Iterate through the map and print each key in the order they appearThis will give you a sorted list of unique wordsHere's the expected result: "a big cat does everything feeding goats helping injured juvenile kangaroos locating missing notorious objects playing quietly reading superb tales upvoting videos with xylophone yielding zebras" PART 3Iterate through the map again, this time printing each associated valueThe values represent how many times each word was found in the text filePay attention to the sequence of…PLEASE DO YOUR OWN CODING NO COPYING Write an assembly program to compute the following expressions - Create a DWORD array named ‘z’ of size 3 using DUP operator. Leave the array ‘z’ uninitialized.You can denote the items in the array as [�!, �", �#], where �! is the first item, �" is the second item,�# is the third item- Update each array item using the following expressions. �! = � + 130�" = � + � − �!�# = � + � − 13 - Where x, y, r are 16-bit integer memory variables.- x = 10, y = 15, r = 4- Use mov, movzx, movsx, add, sub instructions only.- (hint: Do not alter the value of x, y and r during the computation. Transfer them to appropriate registers to docomputation)- At the end, open memory window to see the variable z stored in memory (little endian format).- If you code correctly, �! = 140 in decimal, �" = −115 in decimal, �# = 1 in decimal § Screenshot of the code and memory window showing the content of the variable z (little endianformat).
