,Features of C Language
, Features of C Language
▪ Simple
C is a simple language in the sense that it provides a structured approach (to break the
problem into parts), the rich set of library functions, data types, etc.
▪ Machine Independent or Portable
Unlike assembly language, c programs can be executed on different
machines with some machine specific changes. Therefore, C is a machine
independent language.
▪ Mid-level programming language
Although, C is intended to do low-level programming. It is used to develop
system applications such as kernel, driver, etc.
It also supports the features of a high-level language. That is why it is known
as mid-level language.
▪ Structured programming language
C is a structured programming language in the sense that we can break the
program into parts using functions.
So, it is easy to understand and modify. Functions also provide code reusability.
, Features of C Language
▪ Rich Library
C provides a lot of inbuilt functions that make the development fast.
▪ Memory Management
It supports the feature of dynamic memory allocation. In C language, we can free
the allocated memory at any time by calling the free() function.
▪ Speed
The compilation and execution time of C language is fast since there are lesser
inbuilt functions and hence the lesser overhead..
▪ Pointer
C provides the feature of pointers. We can directly interact with the memory by
using the pointers.
▪ Recursion
In C, we can call the function within the function. It provides code reusability for
every function. Recursion enables us to use the approach of backtracking.
▪ Extensible
C language is extensible because it can easily adopt new features.
