Computer Science: A Structured Programming Approach Using C Text versus Binary Streams In this section, we compare and contrast text streams versus binary streams. Text and Binary Files Differences between Text and Binary Files State of a File Opening Binary Files Closing Binary Files Topics discussed in this section:

Computer Science: A Structured Programming Approach Using C Standard Library Functions for Files C has eight categories of standard file library functions. We have already discussed the first four in Chapter 7 and Chapter 11. We discuss the other four categories, which are more related to binary files, in this section.
