C++ Footprint and Performance Optimization

Chapter 12. Optimizing IO

IN THIS CHAPTER

• Efficient Screen Output

• Efficient Binary File IO

• Efficient Text File IO

As a C++ implementer you have access to the standard C functions for performing IO as well as the new streaming classes introduced by C++. It is not always obvious, however, what the differences between these techniques are—apart from their notation—and whether there are performance penalties involved in using a certain technique. This chapter looks at the pros and cons of each technique and notes where to use each.
