  Kindly make the c++ function of the given algorithm Suppose P is an arithmetic expression in postfix notation

Computer Science

 

Kindly make the c++ function of the given algorithm Suppose P is an arithmetic expression in postfix notation. We will evaluate it using a stack to hold the operands.

     Start with an empty stack.  We scan P from left to right.

     While (we have not reached the end of P)
        If an operand is found
           push it onto the stack
        End-If
        If an operator is found
           Pop the stack and call the value A
           Pop the stack and call the value B
           Evaluate B op A using the operator just found.
           Push the resulting value onto the stack
        End-If
    End-While
    Pop the stack (this is the final value)
