Hi, I hope someone can help.
I have a class called cField, and another class called cFieldList.
cFieldList contains a std::vector of cFields called myvec
I've overloaded the subscript operator for cFieldList as so:
cField& operator(int pos) { return myvec; }

Hi, I have a class called cList as so:
template<class T> class cList { // base class for Lists
private:
protected:
vector<T> tListOf; // field list container
public:
void Add(const T& t) {tListOf.push_back(t);} // add new object to list
unsigned int Count() { return tListOf.size(); } // number of list items

Hi,
I am not exactly new to C++, but I have never done operator
overloading before.
I have some old code that tries to implement a Shift Register - but I
cannot seem to get it to work. Here's a simpler version of it.
-------------------- main.cpp---------------------------
# include <iostream>

I run into a strange warning (for me) today (I was trying to improve
the score of the UVA #10018 Programming Challenge).
$ gcc -W -Wall -std=c89 -pedantic -O2 10018-clc.c -o 10018-clc
10018-clc.c: In function `main':
10018-clc.c:22: warning: array subscript has type `char'
I don't like warnings ... or casts.

Hi I've a dubt!
when we have overloaded functions the compiler chooses the right
being based on the argument lists...but when we have two subscript
overloaded functions it resolves them being based on the const type.
Infact if I use the Array on the left side i.e like a1 = 111
then it uses the first while if I use cout << a1 it uses the
second...
why????

Hi all
This seems to me a peculiar problem, but confounding nonetheless...
The problem seems to be that an overloaded subscript operator isn't being called unless it is called explicitly
struct myStruct
{
myStruct& operator (int index)

I have a custom String class that contains an embedded char* member.
The copy constructor, assignment operator etc. are all correctly
defined. I need to create a map of my string (say a class called
MyString) and an integer i.e. std::map<MyString, int>. Whenever I
insert the elements in the map using the subscript operator, I
noticed that the copy constructor for MyString is invoked more number
of times than if I do it using the insert()...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...
