    i am surprised it got to the linker??
    remove the bracket after void modify() {} -> } and put a bracket after switch case.
    this will end the main and the linker will find the functions it is complaining for

    Hi,

    Can you please re-paste your code snippet in the correct format? Its really difficult even reading your code to understand what you want to do.

    Thanks,
