Question

This is a computer programming assignment to be done in C++ format. This assignment is based on computer language. If you upload screenshots i would be thankful.

Assignment Write a program that will determine the resultant of three forces. The program must . Prompt for the units Prompt for the magnitude and direction of each force Output the resultant magnitude, direction and correct units. Bonus: the program should ask the user if they want to run the program again. The program should run as long as the user wants to perform more calculations, and terminate when the user types "no." Submit a copy of your flowchart or pseudocode and your source file . Marking Scheme: . Prompt for units 5 points Prompt for magnitude and direction-5 points . Output correct result-5 points · Flowchart-3 points Formatting and comments -2 points Bonus-5 points Deductions:
