Description:
The program should read a postfix expression consisting of digits and operators into a character array.It should scan and evaluate the expression.The algorithm is as follow:

1.append the Null character('\0')to the end of the prefix expression.When the Null character is encountered,no further processing is needed.

2.While '\0'hasn't been encountered,read the expression from left to right.
if the current character is a digit,push its integer value onto the stack.Otherwise, if the current charater is operator,pop the two top elements of the stack into variables x and y.push the result of the calculation onto the stack.

3.When the Null character is encountered in the expression,pop the top value of the stack.This is the result of the postfix expression.

Functions:
a. evaluatePostfixExpression
b. calculate
c. push: pushes value onto stack.
d. pop: pops a value off stack.
e. isEmpty: determine if stack is empty.
f. printStack
