What our customers are saying

At a Glance: C

Developed by Dennis Ritchie in 1969 at AT&T Bell Labs, C is an imperative programming language that has gained widespread use across the globe for its simplicity, efficiency, and inherent affinity with machine-readable code. If you desire portability and efficiency, compatibility with a wide range of platforms and operating systems; are developing software for Unix; or require low-level access to memory, you’ll need the expertise of a seasoned C programmer.
C supports structured programming, lexical variable scope and recursion, making it an especially popular language for systems programming. A C programmer can help you implement an operating system on your network or implement paging virtual memory or device driver software for your operating systems. They can take advantage of the language’s thin layer of abstraction and low overhead to write efficient algorithms and handle large data structures. C developers are often experts at GPU programming, data analysis, machine learning, image processing, pattern recognition, and data mining. With the help of C programmers on Upwork, you can build new operating systems, program digital devices, and bring your data-intensive or assembly-level projects to life.

What Is Object-Oriented Programming & Why Is It Important?

You’ve probably seen most back-end programming languages described as object-oriented programming (OOP)—so what is object-orientation in web development, and why is it important? At its core, it’s a logic—one we use in daily life. We naturally think of things as objects with attributes and behaviors, and that determines how we interact with them. It’s interacting in the abstract, and it’s why OOP can boost speed and efficiency.
