C language

A C Language Computer Course focuses on teaching the fundamentals and advanced concepts of the C programming language. C is one of the oldest and most widely used programming languages, renowned for its efficiency and versatility. It is the foundation of many modern programming languages, such as C++, Java, and Python, and is widely used in system programming, embedded systems, and applications requiring high performance.

Here’s a typical C Language Computer Course Content outline:
