Operator Overoverloading

Name: Cudder !MhMRSATORI!fR8duoqGZdD/iE5 2013-02-22 6:56

Studying part of a large complex middleware for a management web application, and wondering why this:
InitechString str1, str2;
...
if(!(str1 != str2))
{
    ...
}

occurred almost as often as this:
InitechString str1, str2;
...
if(str1 == str2)
{
    ...
}

I dug a little deeper and found...


// CASE-SENSITIVE COMPARISON
//
int InitechString::operator==(const InitechString& r) const
{
    return !strcmp(m_ptr, r.m_ptr);
}
// CASE-NONSESTIVE COMPARISON
//
int InitechString::operator!=(const InitechString& r) const
{
    return !!strcmp(m_ptr, r.m_ptr);
}

That's a problem with the programmer/education, not the language.

template class dllist<typename T> {
 struct dllist<T> *prev;
 struct dllist<T> *next;
};

class person : public dllist<person> {
 int age;
 int weight;
};

That blog post was shot down pretty hard in the comments.

That gets what's desired in this case, and it's concise, but you no longer have the ability to have a person without the linked list node embedded in. That's what disappointed me about their use of C in the blog, and the in the comments.

I dislike C++: it is too verbose, complicated and obfuscated:

Symta:
<Age:|Weight:>

C/C++:

template class dllist<typename T> {
 struct dllist<T> *prev;
 struct dllist<T> *next;
};

class person : public dllist<person> {
 int age;
 int weight;
};

No. It's lambda.
