5.2 Conclusion

This chapter has demonstrated the basics of C++. Specifically, it has explained how preprocessor directives are used to instruct the compiler how to assemble the code, and more importantly how the #include directive can take code from other files and include them into existing programs to be reused. Furthermore, it has explained how program execution begins and ends at the main function and how code included between its braces ({}) is said to be contained within the function. The next chapter considers C++ in more detail.
