PostfixA Program Evaluator
You will write a program that evaluates a program written in a language called PostfixA. PostfixA is a fairly simple language that only allows assignment statements and integer arithmetic. Your program asks the user for a file containing a PostfixA program. If the file contains a syntactically valid PostfixA program, then your program should output to the screen the value of each variable. If not, then an error message should be printed to the screen simply stating that the program is NOT a valid PostfixA program.
