With a lot of attention focused on newer object-oriented languages like Python, you might not think C++ is used for much any more.
The truth is C++ is still in demand by top tech companies across the world. Employers are specifically interested in applicants with a strong understanding of optimization through the standard library.
Today, we’ll walk through what the standard library can do for you and some top library components to use in your next project.
Here’s what we’ll cover today:
Programming languages like Python may be steadily rising in popularity, but C++ is faster than any of them. C++ is very close to the hardware level, making it the best programming language for making hardware run faster.
For big companies like Google and Facebook, just a 10% increase in server performance is a big savings in electricity alone. These companies (no matter what the new, popular object-oriented programming language they use) continue to hire C++ programmers to optimize their back ends, and solve scaling issues.
Yep, knowing C++ could land you a job at Google or Facebook.
The C++ Standard Library is a reference to help you at every step of your projects related to system programming.
Even if you’re proficient in core C++, understanding the Standard Library will make you a valuable programmer. It allows you to:
The code in the Standard Library is tested by hundreds of thousands of people and gets subjected to more testing and scrutiny than anything you’d implement yourself.
The Standard Library was developed by the greatest minds in C++ over the past few decades. You are guaranteed good performance, no bugs, and solutions that have been tested and re-tested for decades.
Go with the tried-and-true.
The C++ Standard Library can be categorized into 3 components: containers, iterators, and algorithms.
The containers store collections of other objects, and replicate structures used over and over again in programming (arrays, queues, stacks, etc.). The algorithms can be used on ranges of elements. And the iterators are like the glue that binds the containers and algorithms — they’re used to move forward, backward, or to an arbitrary position in the container.
Here’s an extensive list of items in the C++ Standard Library:
Each of library components have their own benefits to your programs. As you continue your C++ journey, you should learn to implement advanced library tools like:
To help you master these library components, Educative has created C++ Standard Library including C++ 14 & C++ 17. This course will teach you to implement every all the most important library components and introduce you to C++ changes in V14 and V17. By the end, you’ll have the hands-on experience to manipulate and utilize the Standard Library in your own C++ programs.
