Objective: The purpose of this activity is to help the student to use relational and logical operators in mathematical operations and to solve simple programming problems that require the use of relational and logical operators. (Objectives 1 and 2)Student Instructions:1. Modify the following program so that the user enters two values to test if they are equal. It must offer a message for equal values and another for different values. Make sure you print an address (prompt) for each input. Test the program with pairs of equal and different values. 2. Submit your archiveoff.cpp" by Assignment, you will have one attempt to submit the activity successfully. 3. The value of the activity is 10 points. 4. The deadline for answering the questions can be found in 'Tools' which is found in "Calendar" within the Blackboard platform.
C++ Assume num is an integer. Write statements that will create a variable that can point to an int and store the address of num in the variable.
Lecture Activity # 5 – Design Tools (Flowchart) Instruction: Create a program plan, algorithm, and a flowchart for the following case: Design the algorithm for a program that calculates the current balance in a savings account. The program should obtain from the user the following information: the starting balance, the total amount of deposits made, the total amount of withdrawals made, and the monthly interest rate. After the program has calculated the current balance, it should be displayed on the screen. Assume one input for deposits and one input for withdrawals. Draw the flowchart for this algorithm.

A and BonlyIn this program, you are asked to write a program in assembly which works as a simple calculator.The program will get two integer numbers, and based on the requested operation, the result shouldbe shown to the user.a. The program should print a meaningful phrase for each input, and the result.i. “Enter the first number”ii. “Enter the second number”iii. “Enter the operation type”iv. “The result is”b. The user should enter 0, 1, and 2 to tell the program the types of operation add, sub, andmultiply, respectively.c. How many registers do you need to implement this program?d. What system calls do you need to write this program?
Problem Definition Write a Python program that calculates the perimeter and area of multiple simple geometrical shapes based on the user's selection. Let the program handle the perimeter and area calculations for circle, rectangle and parallelogram shapes. The program should display a menu of the three shapes, and then allow the user to select one of the options. Accordingly, the program would request from the user to enter the required parameters of the corresponding geometrical shape in floating- point form (e.g., radius of a circle, or the width and length of a rectangle). When you finish a shape prompt the user to see if there are more shapes to process. The program should: interact with the user in a friendly way using a menu listing the different shapes (C: Circle, R: Rectangle, P: Parallelogram). display an error message for invalid shape options for a parallelogram, keep asking the user until a valid angle (within 0 and 180 degrees) is entered. compute the perimeter and the…

Instructions C++ 8-17 A company hired 10 temporary workers who are paid hourly and you are given a data file that contains the last name of the employees, the number of hours each employee worked in a week, and the hourly pay rate of each employee. You are asked to write a program that computes each employee’s weekly pay and the average salary of all employees. The program then outputs the weekly pay of each employee, the average weekly pay, and the names of all the employees whose pay is greater than or equal to the average pay. If the number of hours worked in a week is more than 40, then the pay rate for the hours over 40 is 1.5 times the regular hourly rate. Use two parallel arrays: a one-dimensional array to store the names of all the employees (Name) a two-dimensional array of 10 rows and 3 columns to store the number of hours an employee worked in a week (Hrs Worked), the hourly pay rate (Pay Rate), and the weekly pay (Salary). Your program must contain at least the following…

Assembly language Part 1: When a variable is stored in memory, it is associated with an address. To obtain the address of a variable, the & operator can be used. Write a C program addressOfScalar.c by inserting the code below in the main function. Questions: 1) Run the C program, attach a screenshot of the output in the answer sheet. 2) Attach the source code in the answer sheet 3) Then explain why the address after intvar is incremented by 4 bytes instead of 1 byte.
