myclass is a C++ class written by me and when I write:
myclass x; cout << x; How do I output 10 or 20.2, like an integer or a float value?

The cout object in C++ is an object of class ostream. It is defined in iostream header file. It is used to display the output to the standard output device i.e. monitor. It is associated with the standard C output stream stdout.
yes of course you can add two object of same class but before doing that you have to do operator overloading , by defining the '+' operator and how the objects are going to add when u simply put a '+' operator between the object.
Typically by overloading operator<< for your class:
struct myclass { int i; }; std::ostream &operator<<(std::ostream &os, myclass const &m) { return os << m.i; } int main() { myclass x(10); std::cout << x; return 0; } If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
