help in overloading ostream op

hi,
i have to create a program that will print the 52 cards in a deck using
the overloaded ostream operator. it worked fine....then i hve to create
a function that will print the cards in hand in random(5, 10).

//error it shld only have two parameters
ostream& operator<<(ostr eam& out, vector<Card>& deck2, vector<Card>&
hand)
{

for(unsigned int i = 0; i < hand.size(); i++)
{
int random;
random = randNum(0, 51);

//if the card is picked, don't add it in
hand,instead add another card/s in the vector
if(deck2[random].isPicked())
{
deck2[random].printCard(out) ;
out << endl;
int last = hand.size() - 1;
hand.push_back( hand[last]);
for(int i = last; i > deck2[random].isPicked();
i--)
{
hand[last] = hand[last - 1];
}

}

else
{
hand[i] = deck2[random];
deck2[random].setPicked(true );
hand[i].printCard(out) ;
out << endl;
}
}
return out;
}

what shld i put in the parameters of ostream& operator<<(..) in order
to print the card in hand

I think you need to define your problem better.
As you noted operator<< should only have two operands.

You should separate the generation of the hand from the deck
from outputing a hand or a single card. I suggest the following.

First write
ostream << Card;

Then using that also write
ostream << vector<Card>

Then right other functions that make the deck and hands.

I would suggest it would be easier if you actually removed the
cards from the deck after it is picked rather than maintaining
some sort of picked state. Think about the real world you're
attempting to model here.

Hey all I have a class Foo, and I'm trying to overload the << operator for both the ostream and ofstream for it. This way I should have two seperate formats for output, one for files and another for the screen. Right now the two declarations are: std::ofstream& operator<<( std::ofstream &fos, const Foo &theClass); std::ostream& operator<<( std::ostream &fos, const Foo &theClass);

I've been working on creating a Complex class for my own learning purpose (learn through doing etc.). I'm once again puzzled about something. I can't figure out how to overload the assignment operator. Here's what I'm trying to do. I've defined class Complex as class Complex { friend ostream &operator<<( ostream &, Complex & ); public: Complex( float = 0.0, float = 0.0 );

I have defined a number of custom stream buffers with corresponding in and out streams for IO operations in my program, such as IO::output, IO::warning and IO::debug. Now, the debug stream should be disabled in a release build, and to do that efficiently, I suppose I need to overload the << operator. My current implementation of the stream in release mode is posted below. Everything works fine for POD type like bool and int, but the...

Hi I'm really new to c++ so please forgive me if this is really basic but im stuck... I am trying to make a data class that uses istringstram and overloaded << and >> operators to input and output data. The data comes in string lines like "OREBlegQ 14854 731.818" which need to be split into a string, int and double when stored in the class. Can anyone help? This is what i have so far: /* Begin Code */ #include <sstream>

I always understood that in C++, if I said a + b a.operator+(b) is called. Now this makes sense with the operator<< when used in the following way cout << 100; // converts to cout.operator<<(100);

Hello, this program might look abit long, but it's pretty simple and easy to follow. What it does is read from a file, outputs the contents to screen, and then writes them to a different file. It uses map<and heavy overloading. The problem is, the output file differs from input, and for the love of me I can't figure out why ;p #include <iostream> #include <fstream> #include <sstream>

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: ";

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
