Figure 1. C++ Demo Code
"C++ is a general-purpose programming language with a bias towards systems programming that is a better C; supports data abstraction, object-oriented programming, and generic programming."
- Bjarne Stroustrup, creator of C++
There are four ways of viewing Cpp content in this site:
  1. Cpp Story
    An ebook with seven chapters that covers Cpp programming at intermediate level.
  2. Cpp Bites
    A large collection of pages each focused on one feature of the Cpp programming language, starting with basics.
  3. Blogs
    There is now, as of 07 Jan 2025, one C++/Rust blog. That is expected to change eventually.
  4. Compiler Explorer
    An on-line code editor and executor
It's easy to sample each of these views by using the links above, or more selectively, using links in the CppExplorer panel on the left (if you don't see it, click on page header). Cpp Highs and Lows
The code above on the right illustrates a Cpp "ShowType" function, useful for evaluating standard library and user-defined types when learning a new language.
Everything below this line is a place-holder for content to come.

Exercises

  1. Write a Cpp program to find the largest file in a specified directory tree, using walkdir crate from crates.io.
  2. Ammend Project #1 by accepting arguments from the command line, using args crate.
  3. Use ChatGPT to create a directory traversal crate and use that instead of walkdir.
  4. Write a Cpp program to read a source code file and count the number of lines and number of scopes for each function. You can count scopes by counting open braces "{". Start by searhing for fn and then read each line searching for "{" and "}". Push each open brace on a stack, and pop when a closed brace is encountered. When the stack is empty, the end of the function has been reached.
  5. Modify Project #4 by counting lines and scopes for each file in a directory tree rooted at a specified folder, usually named "src".
