1. Computer Science: A Structured Programming Approach Using C1 2-7 Input/Output Although our programs have implicitly shown how to print messages, we have not formally discussed how we use C facilities to input and output data. We devote two chapters, Chapter 7 and 13, to fully explain the C input/output facilities and how to use them. In this section, we describe simple input and output formatting. Streams Formatting Input/Output Topics discussed in this section:
