Write a very simple test program, similar to Test_Employees, that repeatedly

• prompts the user for a VString representing an infix expression with no parentheses
• calls RPN_Priorities (Prog. 7.6) to convert the expression to RPN
• displays the RPN string

Use VStrings and VString.IO.

Test this for a large number of expressions. You can just put the program in an endless loop and quit by pressing ctrl-C.

Now do Exercise 6, p. 311.
