Example:
(a+b)
in order to get the postfix of this i would call
Console.WriteLine(“\n\nResult is: {0}\nPress enter to exit.”,tokens);
But the output is this:
Postfix.Token[]

Why is that so???

default:
if (!float.TryParse(arg, out token.Operand))
throw new ArgumentException(“Unknown token: ” + arg);
token.Operator = arg[0];
token.Precedence = 0;
break;

These part should be replaced right?
Therefore, i should omit the if statement and then store “a” in the Token Class…how about the throw – new ArgumentException it should be omitted also???

I’m sorry if I have so many questions.
I’ve been sleeping very late because of this machine problem.
Although,this should be group project but as you can see sir,I am the only person who is doing this project.

So, I would appreciate all these things sir from the bottom of my heart.

Sir, how would I accept it as it is?

I confirmed you already as my friend in Facebook.

Anyway, I’m just a 2nd year college taking up BSIT.

Thank you very much for the advice on how to revise your code into an algebraic expression…

I would appreciate if ever there would be an error on my program and you’ll extend your assistance.

Again, thank you very much sir…:)

Your program accepts arithmetic expression…

Sir, may I ask question?

In what way can I revise this program where in it will accept an algebraic expression?

Example:
a+b -> to infix ab+

By the way, your program accepts algebraic expression or arithmetic expression or both???

Error 1 Operator ‘+’ cannot be applied to operands of type ‘object’ and ‘object’

stack.Push(stack.Pop() + stack.Pop());

Error 2 Cannot implicitly convert type ‘object’ to ‘float’. An explicit conversion exists (are you missing a cast?)

float f1 = stack.Pop();

Error 3 Cannot implicitly convert type ‘object’ to ‘float’. An explicit conversion exists (are you missing a cast?)

float f2 = stack.Pop();

Error 4 Operator ‘*’ cannot be applied to operands of type ‘object’ and ‘object’

stack.Push(stack.Pop() * stack.Pop());

Error 5 Cannot implicitly convert type ‘object’ to ‘float’. An explicit conversion exists (are you missing a cast?)

float f1 = stack.Pop();

Error 6 Cannot implicitly convert type ‘object’ to ‘float’. An explicit conversion exists (are you missing a cast?)

float f2 = stack.Pop();

Error 7 Cannot implicitly convert type ‘object’ to ‘float’. An explicit conversion exists (are you missing a cast?)

float result = stack.Pop();

When I put stack.top and stack.empty there were errors…i don’t know why…Are you using a class to access .top and .empty???

Please…Help me to do this…

If there were certain changes on your code please do notify me…

I will really appreciate it from the bottom of my heart…:)

When I run this in c# there were certain errors…especially on the stack.pop…why is that so???

Please reply…

Thank you very much…:)

God Bless!
