User defined function, how to manipulate it?

[Dimitar]

Hello everyone! I need to ask the user for a function say: X^5 +7 and I need to ask him separately for the value of X, so I can calculate it then. I really don't know how to store the function and then manipulate it!
Thank you!

First step is to just write a program that asks you to enter a value, then use cin to get the value from the keyboard. Once you have that going (compiled without error and runs correctly) you can add the other stuff to it, whic to write a function that contains that formula and returns the result. The function needs one parameter -- the value of x.
