C is a versatile programming language that can be used to develop a wide range of software applications, including:-

• Operating systems: Many operating systems, including Unix, Linux, and Windows, are written in C.
• System programming: C is well-suited for developing system-level programs, such as device drivers, network protocols, and file systems.
• Embedded systems: C is commonly used in the development of embedded systems, such as microcontrollers, digital signal processors, and other specialized hardware.
• Game development: Many game engines, such as Unity and Unreal Engine, offer C as a programming language option for game developers.
• Desktop applications: C can be used to create desktop applications, such as text editors, media players, and image editors.
• Web development: While not as popular as other languages such as JavaScript or Python, C can be used to develop web applications through frameworks like CGI (Common Gateway Interface) or FastCGI.
• Artificial intelligence and machine learning: C can be used in the development of machine learning and artificial intelligence algorithms and libraries, such as TensorFlow and OpenCV.
• Security software: C is a common language for developing security software, such as antivirus programs, firewalls, and intrusion detection systems.
