C programming language was developer in the mid-1970’s. C programming is considered as a mother of all programming language. This programming language supports various functions such as hardware units and kernels. It was mainly developed to write operating systems.
Features of C programming language
- High-Level language
Programming language are strong in terms of in-built features and libraries. This allows the system to be machine-independent. It can develop system application such as driver, kernel, etc.
- Structures language
Its supports the structure of the program which consists of the functions. The functions will also decrease the code complicity which can also be reused.
- Rich library
It incorporates various arithmetic and logical functions with a wide range of in-built libraries which can be faster and convenient.
It opens for more upgrades in features. It is considered as extensible such as high-level language.
It supports functions which involves recursion. It is when a function is used within other functions for multiple number of times.
It directs to interact with memory with the use of pointers. You can work on memory, structure, functions, arrays and more.
It works with minimal numbers of libraries and built-in functions which can compile and execute systems to face low overhead.
- Memory management
It can allocate can deallocate memory dynamically. The functions can allocate various memories dynamically.
Data types and variables
Basic datatypes // It is used as the most fundamental and primary database. The database is as follows;
|Datatype name||Datatype size||Datatype rnage|
|Short||1 Byte||-128 to 127|
|Unsigned short||1 byte||0 to 255|
|Char||1 byte||-128 to 127|
|Int||2 bytes||-32,768 to 32,767|
|Long||4 bytes||-2,147,483 to 2,147,483,647|
It is formed with one or more basic types in various combination.
- Function types
- Pointer types
- Array types
- Structure types
- Union types
Used to speak out about integral constants which is used to remember and maintain.
An empty data type which is used to return the functions no value in C.
Variables in C
- Local variable
- Global variable
- Static variable
- Automatic variable
- External variable
