Head First C

Chapter 4. Using Multiple Source Files: Break it down, build it up

If you create a big program, you don’t want a big source file.

Can you imagine how difficult and time-consuming a single source file for an enterprise-level program would be to maintain? In this chapter, you’ll learn how C allows you to break your source code into small, manageable chunks and then rebuild them into one huge program. Along the way, you’ll learn a bit more about data type subtleties and get to meet your new best friend: make.

C can handle quite a few different types of data: characters and whole numbers, floating-point values for everyday values, and floating-point numbers for really precise scientific calculations. You can see a few of these data types listed on the opposite page. See if you can figure out which data type was used in each example.

Remember: each example uses a different data type.
