- Computer Science JAVA: If you wanted to test two variables for equivalency, what operator do you use? Give two circumstances in which that operator does not perform as expected, and why.Problem Statement: (The following problem is based on a problem in a number of Java texts, including the text by Gaddis.) Given a numeric expression in prefix form, develop a Java program to evaluate the expression. The following site provides some explanation on prefix expressions, as well as other forms of numeric expressions: Infix, Prefix and Postfix Expressions (Links to an external site.) Input Data: Repeatedly, enter one prefix expression (as a string) at a time at the keyboard alternatively, you may set up an input data file and get the data from the file Stop the inputting, when the user does not want to enter any additional strings NOTE 1: To simplify matters, assume that only non-negative integers are used the allowed operations are binary addition/subtraction, multiplication, division, and modulus operations Processing: Set up a method (or methods) to evaluate the given expression. Output Data: Echo back the entered input string, along with the result…Develop an algorithm for the following problem statement. Your solution should be in pseudocode with appropriate comments. Warning: you are not expected to write in any programming-specific languages, but only in the generic structured form as stipulated in class for solutions design. A coffee shop pays its employees biweekly. The owner requires a program that allows a user to enter an employee's name, pay rate and then prompts the user to enter the number of hours worked each week. The program validates the pay rate and hours worked. If valid, it computes and prints the employee's biweekly wage. According to the HR policy, an employee can work up to 55 hours a week, the minimum pay rate is $17.00 per hour and the maximum pay rate is $34.00 per hour. If the hours work or the pay rate is invalid, the program should print an error message, and provide the user another chance to re-enter the value. It will continue doing so until both values are valid; then it will proceed with the…

- Read problem carefully. • Solve problem using 5-steps of Engineering Problem Solving Methodology (including algorithm) Draw flowchart diagram 3 Write a C++ program Problem Statement: An election is a formal group decision-making process by which a population chooses a candidate by casting votes. Each candidate is assigned name and a specific symbol. A ballot paper is used to cast the vote. Each ballot paper contains symbols of the candidate. A person can vote a candidate by stamping on a specific symbol. The ballot paper should be considered as a spoilt ballot if a person does not stamp or stamp on more than one symbol. Finally ballot paper has to be dropped in a ballot box. Write a C++ program that reads the information from the user to enter the name of the candidate, the total number of received votes, and the spoilt votes in a local election. The total number of participants (candidates) are 5. If the user mistakenly enters any negative value, the program should consider that value…Mathematical functions introduced in chapter 4 can be used in the mathematical calculations and simulations of the engineering and scientific problems. In these cases, we formulate the mathematical problem and then use the computer for calculations and simulations. Can a computer code solve the math problem and come up with mathematical formulas, i.e. can a computer program do what a mathematician does?(Conversion) a. Write a C++ program to convert meters to feet. The program should request the starting meter value, the number of conversions to be made, and the increment between metric values. The display should have appropriate headings and list the meters and the corresponding feet value. If the number of iterations is greater than 10, have your program substitute a default increment of 10. Use the relationship that 1 meter = 3.281 feet. b. Run the program written in Exercise 6a on a computer. Verify that your program begins at the correct starting meter value and contains the exact number of conversions specified in your input data. c. Modify the program written in Exercise 6a to request the starting meter value, the ending meter value, and the increment. Instead of the condition checking for a fixed count, the condition checks for the ending meter value. If the number of iterations is greater than 20, have your program substitute a default increment of (ending value - starting value) / 19.

Shipment check-in is an important part of the business operations as well getting a quick overview as to the profitability of the shipment. Your task will be to design, write, and implement a Python program that will check-in the five cars that are being delivered in this week’s shipment and also calculate potential gross profit (and adjusted based on type of car), as well as totals for cost, MSRP (manufacturer’s suggested retail price), potential gross profit, and potential adjusted gross profit. As your program executes, it should: 1. As part of the check-in, prompt the user to enter the car name (e.g., Red 1969 Triumph TR6), MSRP (manufacturer’s suggested retail price), cost, and code of the type of car (0 = domestic or 1 = import) for each car 2. Once the check-in is complete, your program should then print out a summary of the shipment including:…Theme: Consider that you have been hired as a programmer in a software development company. The Ministry of Education have asked your company to develop a program that assists high school teachers to write report cards for their students.
