C Language Course

 

C Language Course Overview

C programming language is so popular and used so widely is the flexibility of its use for memory management. Programmers have opportunities to control how, when, and where to allocate and deallocate memory. Memory is allocated statically, automatically, or dynamically in C programming with the help of malloc and calloc functions.

Initially, C was designed to implement the Unix operating system. Most of the Unix kernel, and all of its supporting tools and libraries, were written in C. Later other folks found it useful for their programs without any hindrance, and they began using it.

Another strong reason of using C programming language is that it sits close to operating system. This feature makes it an efficient language because system level resources, such as memory, can be accessed easily.

C is good choice for system-level programming. Nevertheless, it is not perfect for all programmers and all situations. C pointers are a common source of confusion and programming errors. C also lacks explicit support for useful abstractions such as classes and objects. That may be a reason C is not preferable language for application-level programming. Newer languages such as C++ and Java address these issues for application-level programs.

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations.
