Slowly, you will move into object-oriented coding and learn things like Inheritance , Abstraction , Encapsulation , etc. After this, you will learn about more advanced concepts like Pointers and Memory management. In this course, you will learn by doing stuff and building skills one level at a time. After that, you will learn by writing a Hello World program and to deal with input and output, i.
You will also learn to create several applications to explore different concepts, e.
But, this course will help you understand the syntax of templates. It gently takes you through the basics and then slowly builds upon the advanced concepts such as specialization, variadic templates, etc. Thanks for reading this article.

Here is a detailed object-oriented design example , that goes through the entire process from start to finish. The final code is written in the Java programming language, but you'll be able to read through it given how far you have come.
Why would I want to learn C or C++?
Please take the time to work through this entire example. It's a great illustration of the process, and the design tools that support it. Testing is a critical part of the software engineering process.
A unit test is a particular kind of test, which checks the functionality of a single, small module of source code. The test drivers you used to test the Composer and Database classes are examples of unit tests. In reality, we cannot attain complete "code coverage" with our testing. Code coverage is an analysis method that determines which parts of a software system have been executed covered by the test case suite and which parts have not been executed. Consider coming up with unit tests for all independent paths of the following.
This can quickly become an exponential problem. We test for things like:. Most unit test frameworks use assertions to test values during execution of a path. Assertions are statements that check whether a condition is true. The result of an assertion can be success, nonfatal failure , or fatal failure. After an assertion is performed, the program continues normally if the result is either success or nonfatal failure. If a fatal failure occurs, the current function is aborted. Tests consist of code that sets up state or manipulates your module, coupled with a number of assertions which verify expected results.
If all assertions in a test are successful, i.

A test case contains one or many tests. We group tests into test cases that reflect the structure of the tested code. In this course, we are going to use CPPUnit as our unit test framework. Find an appropriate directory and place the tar. Then, enter the following commands in Linux, Unix , substituting the appropriate cppunit file name:. If you are working in Windows, you may need to find a utility to extract tar.
The next step is to compile the libraries. Change to the cppunit directory. Usually, you need to run:. If everything compiles okay, then you are all set. There is an excellent tutorial available here. Please go through this tutorial and create the complex number class, and its associated unit tests. You're already familiar with one reason: We need some way of checking our work while developing code.
Even when we're developing a very small program, we instinctively write some sort of checker or driver to make sure that our program does what's expected. From long experience, engineers know that the chances that a program will work on the first try are very small. Unit tests build on this idea by making testing programs self-checking and repeatable.
The C++ Tutorial
The assertions take the place of manually inspecting output. And, because it's easy to interpret the results the test either passes or fails , the tests can be run over and over again, providing a safety net that makes your code more resilient to change. Let's put this in concrete terms: When you first submit your finished code into CVS, it works perfectly.
And it continues to work perfectly for a while. Then one day, someone else changes your code.

Sooner or later that someone will break your code. Do you suppose they'll notice on their own? Not likely. But when you write unit tests, there are systems that can run them, automatically, every day. So when that engineer X breaks your code, the system will send nasty emails to them until they fix it. Even if engineer X is YOU!
Imagine a monk in the Middle Ages looking at the thousands of manuscripts in the archives of his monastery. Fortunately for him, the manuscripts are organized by content and inscribed with special symbols to facilitate retrieval of the information contained in each. Without such organization, it would be very difficult to find the relevant manuscript.
This activity has become increasingly important over the centuries, especially with inventions like paper and the printing press. It used to be something in which only a few people were occupied. Now, however, hundreds of millions of people engage in information retrieval every day when they use a search engine or search their desktop.
