I need to solve an exercise,I already created the required member function:
void print(ostream& e){
e << this->i << endl;
}
But when I want to call that function,I have no ideea how to create that ostream.I never really worked with anything else than cin,cout,get.Little help?
#include <fstream>
//...
std::ofstream myFile("C:\\mydirectory\\myfile.txt");
//...
myObject.print(myFile);
that's an odd way to print something....
you could do it simpler without passing ostream as an arg
void Print(const char *str)
{
std::cout << str;
}
and another way of doing it
// Friend the function with the class
friend ostream& operator <<( ostream &os,const ClassObj &obj )
{
os << obj.i;
// Return the ostream for daisy chaining
return os;
}
// Now use it like this
ClassObj obj;
std::cout << obj;
// and daisy chain
std::cout << obj << endl << obj << obj;
Hey Guys according to that topic i find the coding related to that topic like:
#ifndef SET_
#define SET_
typedef int EType;
using namespace std;
#include <iostream>
class Set
{
private:
struct Node
{
EType Item; // User data item
Node * Succ; // Link to the node's successor
};
unsigned Num; // Number of user data items in the set
Node * Head; // Link to the head of the chain
public:
// Various functions performed on the set
// Display the contents of the set
//
void display( ostream& ) const;
};
#endif
