In the previous lesson (), we covered how to define a variable that we can use to store values. In this lesson, we’ll explore how to actually put values into variables and use those values. As a reminder, here’s a short snippet that first allocates a single integer variable named …
When you write your programs, the compiler will check to ensure you’ve followed the rules of the C++ language (assuming you’ve turned off compiler extensions, as per lesson ). If you have done something that definitively violates the rules of the language, during compilation the compiler will emit an , …
The C++ standard defines rules about how programs should behave in specific circumstances. And in most cases, compilers will follow these rules. However, many compilers implement their own changes to the language, often to enhance compatibility with other versions of the language (e.g. C99), or for historical reasons. These compiler-specific …
Continuing our discussion of this diagram from the previous lesson (): Let’s discuss steps 4-7. In order to compile C++ source code files, we use a C++ compiler. The C++ compiler sequentially goes through each source code (.cpp) file in your program and does two important tasks: First, it checks …
What is C++17? In September of 2017, the ISO (International Organization for Standardization) approved a new version of C++, called C++17. C++17 contains a fair amount of new content New improvements in C++17 For your interest, here’s a list of the major changes that C++17 adds. Note that this list …
Congratulations! You made it all the way through the tutorials! Take a moment and give yourself a well-deserved (insert something you enjoy here). Now, after breathing a long sigh of relief, you’re probably asking the question, “What next?”. What next? By this point, you should have a solid understanding of …
When writing code, sometimes you’ll run across cases where you’re not sure which of two or more options will be more performant. So how might you tell? The answer is obvious: measure how long each takes to run! While we could measure the amount of time some bit of code …
What is C++14? On August 18, 2014, the ISO (International Organization for Standardization) approved a new version of C++, called C++14. Unlike C++11, which added a huge amount of new functionality, C++14 is a comparatively minor update, mainly featuring bug fixes and small improvements. New improvements in C++14 For your …
By default, derived classes inherit all of the behaviors defined in a base class. In this lesson, we’ll examine in more detail how member functions are selected, as well as how we can leverage this to change behaviors in a derived class. Calling a base class function When a member …
Changing an inherited member’s access level C++ gives us the ability to change an inherited member’s access specifier in the derived class. This is done by using a using declaration to identify the (scoped) base class member that is having its access changed in the derived class, under the new …
