Hi,
I came accross this command line "#define PIDHASH_SZ (4096 >> 2)", but
I didn't find any information about the >> operator. Could anyway give
me a brief explanation?
Thanks,
Andre

Right-shift.
4096 >> 2 is equal to 1024
Think bits. If we take 16 bit ints (for brevity):
4096 is 00010000 00000000
Right shift once:
00001000 00000000 (That's 2048)
Right shift again:
00000100 00000000 (That's 1024)

'>>' is the right shift operator
(4096 >> 2) is 4096 shifted right two bits, or 1024.
One suspects that 4096 or 2 or both were symbolic constants in some earlier
form of the code.

I have tried to implement the overload of these 2 operators.
ostream & operator<<(ostream &out, Person &p){
out<<p.getName()<<" "<<p.getSurname()<<", "<<p.getDateOfBirth()<<endl;

This overload work but I have a curiosty
If I try to approch to the name or to the surname or to the dateofbirth in
this way i receive error:

Hi all.
I have run into a problem of overloading a templatized operator>> by a
specialized version of it. In short (complete code below), I have
written a stream class, STR, which defines a templatized operator>>() as
a member that can deal with the built in C types (int, char, float...)
template <class tType> STR& STR::operator>>(tType & t);
I then attempted to add an overloaded version of this to support my own

It seems that the problems have something to do with the overloading of
istream operator ">>", but I just can't find the exact problem.
// the declaration
friend std::istream & operator>(std::istream & in, const Complex & a);
// the methods correspond to the friend
std::istream & operator>(std::istream & in, const Complex & a)
{
std::cout << "real: ";

In a wx GUI, I would like to let the user choose between >, < or =.
So, I created a combobox and when the user chooses ">" for instance, I

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...
