Try this:

const char MenuString[6][8] = {"UNITS", "TIME", "DATE", "PRINT", "BTOOTH", "SERVICE"};

void DisplayString(const char *cDisplayString)
{
 //do stuff with string
    printf("%s", cDisplayString);
}

int main(int argc, char * argv[]){

    int ucMainMenu = 1;
    DisplayString(MenuString[ucMainMenu]);  //look up variable in array pass string to function

    getchar();

}
