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

Using pointers to structs allows for indirect modification of the properties in a struct. This means that changes made to the struct through a pointer will also be reflected in the original struct, creating a more efficient way to modify and work with the data stored in the struct. Options B, C, and D are incorrect because pointers do not necessarily increase performance, consume less memory, or ease syntax. While they can have these benefits in certain contexts, the main purpose of using pointers to structs is to provide a convenient and efficient means of making indirect modifications to the properties of a struct.
