What is returned by the function that overloads the operator >> for a class?

What is the purpose of a dummy parameter in a function that overloads the post-increment or post-decrement operator for a class?

What type of value should be returned by a function that overloads a relational operator?

How many parameters are required to overload the pre-increment operator for a class as a member function?

How many parameters are required to overload the pre-increment operator for a class as a friend function?

How many parameters are required to overload the post-increment operator for a class as a member function?

How many parameters are required to overload the post-increment operator for a class as a friend function?

Consider the following declaration: template class strange private: type a; type b; a. Write a statement that declares sObj to be an object of type strange such that the private member variables a and b are of type int. b. Write a statement that shows the declaration in the class strange to overload the operator == as a member function. c. Assume that two objects of type strange are equal if their corresponding member variables are equal. Write the definition of the function operator== for the class strange, which is overloaded as a member function

Write the definition of the function template that swaps the contents of two variables.

a. Overload the operator + for the class newString to perform string concatenation. For example, if s1 is "Hello " and s2 is "there", the statement: s3 = s1 + s2; should assign "Hello there" to s3, in which s1, s2, and s3 are newString objects. b. Overload the operator += for the class newString to perform the following string concatenation. Suppose that s1 is "Hello " and s2 is "there". Then, the statement: s1 += s2; should assign "Hello there" to s1, in which s1 and s2 are newString objects.
