• C++ extends the capabilities of C by introducing object-oriented programming, which aids in building complex mobile applications.

C and C++ can be used in mobile application development with frameworks like Qt and the Native Development Kit (NDK) for Android. These frameworks provide developers with the tools and libraries to write efficient, high-performance code that can run on multiple platforms. C and C++ are employed in various mobile applications, including gaming, multimedia, and system utilities.

Network application development involves creating software applications communicate and interact with other devices or systems over a network. C and C++ are widely used in network application development due to their low-level control, efficiency, and networking libraries and protocols support.

• C provides direct access to network interfaces and system resources, making it suitable for developing network applications that require fine-grained control over network operations;
• C++ builds upon C and offers additional features such as classes and object-oriented programming, facilitating the development of scalable and maintainable network applications.

In network application development, C and C++ are utilized to create various types of applications, including web servers, email clients, communication protocols, and network monitoring tools. These languages enable developers to implement network protocols, handle data transmission efficiently, and ensure secure communication. C and C++ offer robust libraries and frameworks for network programming, such as Berkeley Sockets, Boost.Asio, and libcurl. These libraries provide developers with tools for handling network connections, implementing various protocols, and managing data transfer between systems.

Algorithmic programming involves the implementation of complex algorithms and data structures to solve computational problems efficiently. C and C++ are widely preferred for algorithmic programming due to their performance, control over memory, and extensive library support.
