Chapter 9: Problem 44

T F The new operator dynamically allocates memory.

Short Answer

Expert verified
Answer: True

Step by step solution

01

Understanding the new operator

The 'new' operator is a command in certain programming languages, such as C++ or JavaScript, that is used to allocate memory for a new object or data structure. This is done by dynamically creating space in memory for the new object and initializing its values. This process is called dynamic memory allocation.
02

Dynamic memory allocation

Dynamic memory allocation is the process of allocating and deallocating memory during the execution of a program. The new operator performs this task by creating memory space for an object and then deallocating it when the object is no longer needed, freeing up the memory for other uses. This allows a program to manage memory more efficiently than if memory was statically allocated, which could create memory waste or bottlenecks in the program.
03

Evaluating the statement

Given that the new operator is responsible for allocating memory for a new object or data structure dynamically, we can determine that the statement "The new operator dynamically allocates memory" is indeed true.
04

Answer

The statement is True. The new operator dynamically allocates memory, allowing for efficient use of memory in programming languages like C++ and JavaScript.

T F Each byte of memory is assigned a unique address.

What is the purpose of the new operator?

Look at the following function definition. void getNumber(int &n) { cout << "Enter a number: "; cin >> n; } In this function, the parameter n is a reference variable. Rewrite the function so that n is a pointer.
