Mastering C++: A Comprehensive Quiz Based on 'Thinking in C++'

What problem does dynamic memory allocation in C++ solve?

1. Memory fragmentation

2. Improper initialization of objects

3. Stack overflow

4. Pointer arithmetic complexity

The correct answer is: Improper initialization of objects

Dynamic memory allocation in C++ solves the problem of improper initialization of objects. It allows the programmer to control the creation and deletion of objects while the program is running, rather than being limited to only objects created during compilation. The other options mentioned, memory fragmentation, stack overflow, and pointer arithmetic complexity, are also issues that can be addressed by dynamic memory allocation but they are not the primary problem it solves. Memory fragmentation is when there are small chunks of free memory scattered throughout the memory space, making it difficult to allocate larger blocks of memory for objects. Stack overflow is caused by functions or variables taking up more space on the stack than is available, resulting in a program crash. Pointer arithmetic complexity refers to the difficulty in manually allocating and deallocating memory for objects using pointers, which can lead to errors and memory leaks. While these issues can be alleviated by dynamic memory allocation, they are not the main
