    >can someone help.

    Sure. If you tell us what you need help with. Does it compile ? Does it link ? Does it run as expected ? If not, what step fails, and what is the errormessage ?

    void Continue()
    char decide;
    {
    This is very (!) old fashioned, and as you don't use it anywhere else, I guess your compiler will flag you an error for it. Put the variable inside the function.

    When in doubt, read the FAQ.
    Then ask a smart question.

    >>switch ( decide )//use toupper here to convert all to upper case and reduce code length

    don't forget the syntax of switch
    ie
    case XYZ:
    break;
    default:
    break;

    Also at least run it through a compiler and remove the typos.

    ie
    printf("Dealer's total card value is %d.\n", dealerCV);
    if (delaerCV > 21)

    Could you be more specific about the problems.

    Please use the {code} {/code} [using square brackets instead of chicken lips] tags as this makes large code readable.
