6-5 Evaluate Postfix Expression (25分) Write a program to evaluate a postfix expression. You only have to handle four kinds of operators: +, -, x, and /. ElementTypeEvalPostfix(char*expr ); whereexprpoints to a string that stores the postfix expression. It is guaranteed that there is e...
A simple expression has a type, which is either a primitive type or a reference type. In these examples, 52 is a 32-bit integer (int); System.out.println("ABC"); is void (void) because it returns no value; "Java" is a string (String); 98.6D is a 64-bit double-precision ...

Expr4j is a Java library to parse and evaluate mathematical expression strings. The expressions are evaluated usingDijkstra's Shunting Yard algorithm. An expression tree is created from the postfix (or RPN) expression which is then parsed to evaluate the expression. The library is written entirely...
