silly array element counter..

[brcain]

Stroustrup recommends not using arrays. Many coding standards insist on never using arrays.

See "What's wrong with arrays?" at

Unless your array is NULL terminated, you have no way of finding out. This is why you often see array length as argument to array functions.

It may be nice to not impose a particular type of container (like std::vector) on the callers of the int MyClass::MyString method. Sometimes, I like to make these types of methods templatized on an iterator type like this:

template< class IteratorType >
int MyClass::MyString(const IteratorType &iterBegin, const IteratorType &iterEnd)
{
    // Get a count of items passed in.
    const size_t  nNumItems = iterEnd-iterBegin;
 
    // Iterate over the input
    IteratorType iter;
    for(iter = iterBegin; iter != iterEnd; ++iter)
    {
      // Do something here.
    }
}

template< class IteratorType >
int MyClass::MyString(const IteratorType &iterBegin, const IteratorType &iterEnd)
{
    // Get a count of items passed in.
    const size_t  nNumItems = iterEnd-iterBegin;

    // Iterate over the input
    IteratorType iter;
    for(iter = iterBegin; iter != iterEnd; ++iter)
    {
      // Do something here.
    }
}
