It is a robust language with rich set of built-in functions and operators that can be used to write any complex program.

The C compiler combines the capabilities of an assembly language with features of a high-level language.

Programs Written in C are efficient and fast. This is due to its variety of data type and powerful operators.

It is many time faster than BASIC.

C is highly portable this means that programs once written can be run on another machines with little or no modification.

Another important feature of C program, is its ability to extend itself.

A C program is basically a collection of functions that are supported by C library. We can also create our own function and add it to C library.

C language is the most widely used language in operating systems and embedded system development today.

Features of C Language

C is the widely used language. It provides many featuresthat are given below.

Simple
Machine Independent or Portable
Mid-level programming language
structured programming language
Rich Library
Memory Management
Fast Speed
Pointers
Recursion
Extensible

1) 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.

2) 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.

3) 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.

4) 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.

5) Rich Library

C provides a lot of inbuilt functions that make the development fast.

6) 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.

7) Speed

The compilation and execution time of C language is fast since there are lesser inbuilt functions and hence the lesser overhead.

8) Pointer

C provides the feature of pointers. We can directly interact with the memory by using the pointers. We can use pointers for memory, structures, functions, array, etc.

9) 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.

10) Extensible

C language is extensible because it can easily adopt new features.
