This is to be done using C++

Postfix Expressions Calculate 4.99 * 1.06 +5.99 +6.99 * 1.06 Need to know the precedence rules Postfix (reverse Polish) expression 14.99 1.06 * 5.99 +6.99 1.06 * + Use stack to evaluate postfix expressions When a number is seen, it is pushed onto the stack When an operator is seen the operator is applied to the 2 numbers that are popped from the stack. The result is pushed onto the stack Example I evaluate 6 5 2 3 + 8 + + 3 + + The time to evaluate a postfix expression is O(N) processing each element in the input consists of stack operations and thus takes constant time +
