    Okay if I compile your code in the clang++ compiler and ask the compiler to tell me about all warnings ('-Wall') I get the following:

    clang++ -Wall dic.cpp
    dic.cpp:41:1: error: 'main' must return 'int'
    void main()
    dic.cpp:138:9: warning: assigning field to itself [-Wself-assign-field]
    pennies = pennies;
    1 warning and 1 error generated.

    Have a read here for how to get more warnings out of VS (I hope it is still current info for your version) http://blogs.msdn.co...n-visual-c.aspx

    So if I fix the void main() (along with providing a value in the 'return' in main()) and comment out the bad self assignment line then your code compiles with no messages and I get this output
    10002000300040000100110021003100410000101010201030104010011011102110311041100020102020203020402000011001200130014001010111012101310100003 1 1 2

    That doesn't immediately look silly but it is very hard to read.
    Perhaps if you search your code for 'cout' you will find some formatted output instructions your teacher supplied you that you might do well to copy????

    Show us exactly the code you are compiling.

    The stuff you showed us earlier has mistakes in it that I hope you have fixed before this stage so we need to see what you have now.

    What compiler are you using?

    As far as the output, I want to output the new corrected total?

    Well that seems to be likely.
    And how will you get those values? (That's a hint by the way)

    If you want to test for the smallest number of coins required to make up change then one way (there are many) to do it would be like this.

    Get the total amount of money as pennies:
    pennies = pennies
    pennies = pennies + (nickels * 5)
    pennies = pennies + (dimes * 10)
    pennies = pennies + (quarters * 25)

    Now you want to run through the denominations from largest to smallest:
    quarters = pennies / 25
    pennies = pennies - (quarters * 25)
    dimes = pennies / 10
    pennies = pennies - (dimes * 10)
    nickels = pennies / 5
    pennies = pennies - (nickels * 5)

    Is that a rough idea that sparks better ones for you?

    EDIT : Sorry. Total brain failure in original post.

    . . . do i need to just be saying something like
    if ( pennies ==5)

    If you use '==' then it is only going to work when you have exactly 5 pennies. I am certain that is not what you want to test for.
    Wouldn't something more like seeing how many times you can divide the number of pennies by 5 is more like what you want?
    More like:
    nickels = pennies / 5;

    Remember if 'pennies' is a int then C++ will do integer math on the divide and discard the remainder.

    Does that make some sense?

    It's not that I don't get comments left but usually they aren't very nice (because I am not very nice) so I delete them.
    Thanks for 'hi'.

    I don't see how you don't have any comments. I'll be the first to say hi.
