    Help! Math program emergency!

    Hey guys could you help out with a C++ question i just got?
    it goes like this

    Write a program to display the following menu:-

    P) Power
    F) Factorial
    E) Exit

    Request the user to enter a choice. Perform the relevant operation based on the choice entered.

    Choice P:Request the user to enter the base and exponent. Calculate the power of the numbers on the base and exponent entered.

    Choice F: Request the user to enter a number. Then calculate the factorial of the number entered.

    Choice E: User can only exit the program only by entering E or e.

    Other choices: Display "Wrong entry"

    Well show people what you have done so far. Where are the problems with your code? How much of an effort have you made?

    I think just do the normal way like first print the statement MENU using "cout<<".......take a character variable like 'a'.
    and again display the options like """ cout<<****MENU****<<"\n"<<"P - POWER"<<"\n"<<"F- FACTORIAL"<<"\n<<"E-EXIT";
    and again cout<<"Enter the choice";
    assign the choice to the character declared ... ""cin>>a;""
    now take a switch case switch('a')
    and take the options like case P...reditect to a userdefined function power and similarly to factorial. and E for exit ...and keep the default as ""INVALID CHOICE"".
