How do I code? 1. The calculator program will first ask the user for the mode to operate in (Standard or Scientific)
2. The program should then ask the user for the operation to execute (+, -, *, /, sin x, cos x, tan x)
3. In order to know how many times the user will need to perform the operation, prompt the user for the number of floating point values they want to enter (All numbers in this program are double), then ask the user to enter the numbers.
4. Display the result
5. Finally, output the result to the user and ask the user if he/she wants to start over.
