Interpreter Programming Project

CSC $420$ Programming Languages

Below is the syntax and semantics for a single Boolean expression followed by

a period. Write a program which prompts the user to input a file name which

contains the Boolean expression or simply to input the string to be checked

$($indicate which input method you will use in your comments$).$ You may assume

that no input will be longer than $100$ characters in length. Expressions may

contain white spaces and white spaces should be considered to be delimiters

$($i$.$e$.$ a white space between the $$ and $>$ of the implication symbol would be a

syntax error$).$ The program should check if the expression in the file is of valid

syntax and $($if valid$)$ compute the value of the expression. The output should

either be an error message or a message that gives the value of the expression.

You must use the techniques taught in the class $-$ this is a recursive

descent interpreter.
