overloading "<<" with a struct (no class) cout style
- by monkeyking
I have a struct that I'd like to output using either 'std::cout' or some other output stream.
Is this possible without using classes?
Thanks
#include <iostream>
#include <fstream>
template <typename T>
struct point{
T x;
T y;
};
template <typename T>
std::ostream& dump(std::ostream &o,point<T> p) const{
o<<"x: " << p.x <<"\ty: " << p.y <<std::endl;
}
template<typename T>
std::ostream& operator << (std::ostream &o,const point<T> &a){
return dump(o,a);
}
int main(){
point<double> p;
p.x=0.1;
p.y=0.3;
dump(std::cout,p);
std::cout << p ;//how?
return 0;
}
I tried different syntax' but I cant seem to make it work.
