Question

The class Stuff has both a copy constructor and an overloaded = operator. Assume that blob and clump are both instances of the Stuff class. For each of the statements, indicate whether the copy constructor or the overloaded = operator will be called. Stuff blob = clump: clump \(=b 10 b\) blob.operator"(clump): showValues (blob): \(/ /\) Blob Is passed by value.

Short answer

1) Stuff blob = clump; 2) clump = blob; 3) blob.operator=(clump); 4) showValues(blob); Answer: 1) Copy constructor 2) Overloaded assignment operator 3) Overloaded assignment operator 4) Copy constructor

Step-by-step solution

Statement 1 - Stuff blob = clump;

In this statement, a new object called `blob` is being created and initialized with the value of `clump`. Since this is an initialization, the copy constructor is called to create a new object with the same values as `clump`.

Statement 2 - clump = blob;

In this statement, the already existing object `clump` is being assigned the values of `blob`. In this case, the overloaded assignment operator (=) is called since it's an assignment operation.

Statement 3 - blob.operator=(clump);

This statement is equivalent to the previous (`clump = blob;`). It is just written using a different syntax which explicitly calls the overloaded assignment operator function. Therefore, the overloaded assignment operator is called.

Statement 4 - showValues(blob);

For this statement, the `blob` object is passed by value. When an object is passed by value, a copy of the object is sent to the function. In this process, the copy constructor is called to create a copy of the object.
