 you are a tax calculator in company, and you should calculate the tax based on staff’s salary as follows:
-the salary is less than 600, the tax is 0.
-the salary is greater than 600 and less than 800, the tax is 10% of the salary.
-the salary is greater than 800 and less than 1000, the tax is 13% of the salary.
-the salary is greater than 1000 and less than 1500, the tax is 18% of the salary.
-the salary is greater than 1500, tax is 20% of the salary.
Write a program in C++ to ask the user to enter the salary then calculate the tax using:
If-Only structure, If-Else structure, Switch-Case structure.
