Postfix notation

**20.14 (Postfix notation) Postfix notation is a way of writing expressions without using parentheses. For example, the expression (1 + 2) * 3 would be written as 1 2 + 3 *. A postfix expression is evaluated using a stack. Scan a postfix expression from left to right. A variable or constant is pushed into the stack. When an operator is encountered, apply the operator with the top two operands in the stack and replace the two operands with the result. The follow- ing diagram shows how to evaluate 1 2 + 3 *. Write a program to evaluate postfix expressions. Pass the expression as a command-line argument in one string.
