For putting data into the stream and getting data from the stream, the stream insertion and extraction operators are used, Now these operators are already defined for defined datatypes in C++, but for our self-defined datatypes we need to overload these two operators, the code is:
//overloading stream insertion and extraction operators in C++
#include<iostream>
using namespace std;
class point{
private:
int x,y;
public:
point()
{
x =0;
y = 0;
}
friend ostream&operator<< (ostream& cin, point& z){
cin<<z.x<<" "<<z.y<<endl;
return cin;
}
friend istream&operator>>(istream& a, point& z)
{
a>>z.x;
a>>z.y;
return a;
}
};
int main(){
point n;
cin>>n;
cout<<n;
}
In the above code, the steam insertion and extraction operators are overloaded in the overload functions of “<<” and “>>”
