Hi....whats the starting code of it and header file aswell?

Only following Binary operators are allowed for this program:
+, -, *, /, ^ [addition, subtraction, multiplication, division, exponentiation]

If some error occurs while processing postfix expression, your program should display a meaningful message, like:
Error: Division by zero not allowed
Error: Two operands required for __ operator
Error: Invalid postfix expression

Sample Run:
Enter postfix expression to evaluate:
10 20 + Entered by user

The result is: 30

Do you want to enter another postfix expression to evaluate? [Y/N]
Y Entered by user

Enter postfix expression to evaluate:
30 40 + * Entered by user

Error: Two operands required for * operator

Do you want to enter another postfix expression to evaluate? [Y/N]
Y Entered by user

Enter postfix expression to evaluate:
30 40 + 50 60 * Entered by user

Error: Invalid postfix expression

Do you want to enter another postfix expression to evaluate? [Y/N]
Y Entered by user

Enter postfix expression to evaluate:
6 2 3 + - 3 8 2 / + * 2 ^ 3 + Entered by user

The result is: 52

Do you want to enter another postfix expression to evaluate? [Y/N]
N Entered by user

Thank you for using this program.
