Chapter 13: Problem 42

A(n) _________ may be used to pass arguments to the constructors of elements in an object array.

Short Answer

Expert verified

Answer: The term used to pass arguments to constructors of elements in an object array is called an "initializer list". In object-oriented programming, initializer lists help in initializing the objects with specific values allowing each element in the array to start with desired values.

Step by step solution

Identify the term that fits the blank

The term that fits the blank is "initializer list".

Explain the use of an initializer list in object-oriented programming

In object-oriented programming, objects are instances of classes, and constructors allow us to initialize the objects with specific values. An initializer list is used to pass arguments to constructors of elements in an object array, allowing each element to start with the desired values.

Describe an example with an initializer list and object array

Let's consider a simple C++ example with a class named "MyClass" and an object array named "myObjectsArray": ```cpp class MyClass { public: MyClass(int x) : value(x) {} private: int value; }; int main() { MyClass myObjectsArray[3] = { MyClass(1), MyClass(2), MyClass(3) }; } ``` In this example, the initializer list `{ MyClass(1), MyClass(2), MyClass(3) }` is used to pass arguments (1, 2, and 3) to the constructors of elements in the "myObjectsArray". Each element of the array will be created with the corresponding initialized value.
