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

Question: 1 / 565

What is the primary way to use existing code in C++?

Writing new code

Using libraries

To use existing code in C++, the primary method is by using libraries. Libraries are collections of pre-written code that can be easily imported and used in your own code. This saves time and effort compared to writing new code from scratch. Modifying the C++ compiler would require advanced knowledge and can be risky, so it is not a recommended way to use existing code. Option A, writing new code, is not the primary way since it defeats the purpose of reusing existing code. Option D, none of the above, is incorrect as using libraries is the standard and most efficient way to use existing code in C++.
