Developer Tools

The terminal, gcc and its warnings, error messages, header files, make, gdb, testing and Git: the tools around the code.

• Online C compiler
• C code visualizer
• Developer Tools exercises with solutions

1. 1

   The terminal

   Move around folders, run programs, and send files into and out of a program with <, > and |.

2. 2

   Compiling with gcc

   Turn a .c file into a program, switch on warnings, and see the four steps gcc goes through.

3. 3

   Reading error messages

   What a compiler error says, which one to fix first, and the bugs that no compiler can catch.

4. 4

   Programs in many files

   Split a program into .h and .c files, use include guards, and compile the parts separately.

5. 5

   Building with make

   Write a Makefile so one command rebuilds exactly the files that changed.

6. 6

   Debugging with gdb

   Stop a program at a line, step through it, and print its variables with the gdb debugger.

7. 7

   Testing your code

   Check your functions with assert, choose edge cases, and compare a program's output with diff.

8. 8

   Version control with Git

   Save snapshots of your project with Git, see what changed, work on branches, and share with GitHub.
