4.1. Reading Code

This is what developers do every time.

• They read the code.
• Read the lines of code others have written.
• Other developer’s code for code maintenance.
• The API Signatures / Function prototypes
• The values of constants.
• They read the same code written just few minutes back.

Note

Hello World Vs. ZLib

Eclipse is more than what meets the eye. To cover all the features of Eclipse, A Hello World project would not be enough. We have chosen Zlib. The examples / screen shots shown in this book are from Zlib

If you want to take Do-It-Yourself approach along with this book, refer to Setting up Zlib Source and then come back to this chapter.

This is how an opened file, example.c would look in Eclipse.
