WebLook at the discussion given below. For prefix expressions, evaluation is done from the last element to the first element. We create 3 stacks : "P" for Postfix Stack, "I" for Infix Stack and "V" for Value Stack. Let's start the process for all the elements one by one. We have 2 cases: either we will get an operand or an operator. WebOct 25, 2024 · Postfix Expression - Checking for Spaces. So I am trying to add an if statement in my main function to check if there is some whitespace. If so it would just go on to the next number/operator in line. So for example, if I would type 2 3 4 * +, I should get 14. However, when I run the code I would get a random number.
