    Returning a reference to the class? (Chaining)

    I lost my notes when my professor was going over how to "chain" your class by returning a reference to the class somehow (laptop was stolen). Now I can't remember exactly how to return this in the function definition. Any help? See attached shorthand code.

    Code:
    //student.h file> setName function prototype
    class Student{
    public:
    	....
    	Student & setName( const string newName );
    	...
    private:
    	string name;
    	...
    }; // class Student
    
    
    //student.cpp file> setName function definition
    
    Student & Student::setName( const string newName ){
    	name = newName;
    	return ???;
    };
    Thanks in advance!

    You would return *this;

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
