- write three functions in C++: one that declares a large array statically, one that declares the same array on the stack, and one that creates the same array on the heap. Call each of them a number of times (at least 100,000) and output the time required by each. Explain the results.An array is a container object that holds a fixed number of values of a single type. To create an array in C, we can do int arr[n];. Here, arr, is a variable array which holds up to integers. The above array is a static array that has memory allocated at compile time. A dynamic array can be created in C, using the malloc function and the memory is allocated on the heap at runtime. To create an integer array, of size , int *arr = (int*)malloc(n * sizeof(int)), where points to the base address of the array. When you have finished with the array, use free(arr) to deallocate the memory. In this challenge, create an array of size dynamically, and read the values from stdin. Iterate the array calculating the sum of all elements. Print the sum and free the memory where the array is stored. While it is true that you can sum the elements as they are read, without first storing them to an array, but you will not get the experience working with an array. Efficiency will be required later.…6.

- // the language is c++, please code with common for better understanding, and after your code finished take a screenshot of the execution. Write a C++ program to simulate a stack using an array. You should create an index (the stack pointer) to point into the stack. Initialize it to 0. The stack should grow to location [1], [2], [3], etc. Write a "push (int)" function to push an int onto the top of the stack. Also, write an "int pop" instruction to pop the data that is stored on the top of the stack. The pop instruction must return the popped data. The push and pop instructions should increment and decrement the stack pointer appropriately. Your source should contain calls to your functions demonstrating that it works. Note, that you should do several pushes and several pops to show that data is correctly stored on the stack. You can do this by showing sample runs. Cut and paste the results of the runs into a separate documentwrite a program in C++ , (Postfix Evaluation) Write a program that evaluates a valid postfix expression such as 6 2 + 5 * 8 4 / -The program should read a postfix expression consisting of digits and operators into a string. Using modified versions of the stack functions implemented earlier in this chapter, the program should scan the expression and evaluate it. The algorithm is as follows: While you have not reached the end of the string, read the expression from left to right. If the current character is a digit, Push its integer value onto the stack (the integer value of a digit character is its value in the computer’s character set minus the value of '0' in the computer’s character set). Otherwise, if the current character is an operator, Pop the two top elements of the stack into variables x and y. Calculate y operator x. Push the result of the calculation onto the stack. When you reach the end of the string, pop the top value of the stack. This is the result of the postfix…C++ Language: write code. and algorithm or related theory of the following question.

Response Required: Write a program that reads a given text, outputs the text as is, and also prints the number of lines and the number of times each letter appears in the text. An uppercase letter and a lowercase letter are treated as being the same; that is, they are tallied together. Since there are 26 letters, we use an array of 26 components to perform the letter count. We also need a variable to store the line count. The text is stored in a file, which we will call textin.txt. The output will be stored in a file, which we will call textout.txt Input: A file containing the text to be processed. Output: A file containing the text, number of lines, and the number…

The user may enter ANY* arithmetic expression in infix using numbers, parentheses and arithmetic operations (+, -, *, /). After an expression is entered, its postfix or prefix notation is displayed and then the result of the expression.QUESTION: NOTE: This assignment is needed to be done in OOP(c++/java), the assignment is a part of course named data structures and algorithm. A singly linked circular list is a linked list where the last node in the list points to the first node in the list. A circular list does not contain NULL pointers. A good example of an application where circular linked list should be used is a items in the shopping cart In online shopping cart, the system must maintain a list of items and must calculate total bill by adding amount of all the items in the cart, Implement the above scenario using Circular Link List. Do Following: First create a class Item having id, name, price and quantity provide appropriate methods and then Create Cart/List class which holds an items object to represent total items in cart and next pointer Implement the method to add items in the array, remove an item and display all items.

- Write a C++ program with multiple files to include the following: Functional Requirements: Create a type of story game by implementing three dynamic stacks that hold words. The first stack will hold nouns, the second stack will hold verbs and the third stack will hold adjectives. Then we will use the words to fill in the blanks of a story we have already created. Your story (create your own story) must be at least 2 sentences long and it must have at least 6 blanks. You will pull either a noun, verb or an adjective from the appropriate stack as needed for your story. The story must utilize all three stacks, at least one word from each stack. You will be creating a linked list to implement this, using pointers. Programming Requirements: Create a looping menu-driven program to demonstrate your code so that the user has the choice of: 1. Push Noun (push a noun onto the Noun Stack) 2. Pop Noun (pop a noun off of the Noun Stack) 3. Push Verb (push a verb onto…Write a function in C++ that takes a list as input and prints all the unique values in the array only once, i.e., if a value is repeated it should be printed only once.Complete the missing code then compile, debug and test your program using the command lines below: c++ -o project1 project1.cpp <enter> ./project1 n m k <enter> Where n is the size of the stack, m is the modular of the real part and imagination part of a random complex number, and k is the number of elements displayed per line. In the main function, you need to Get the values n, m, and k from the command line. Declare a complex number stack of size n, generate n random complex numbers and push them into the stack.
