C is a commonly used programming language and it is used as a reference language for computer science in the world. This language is learned at school to students at school level with Python language and Java.
C is a low programming language and here we will cover different featues of this language. So let’s get started with
Introduction to C
C is a very famous programming language system for producing different operating systems, databases, and kernel drivers. It was first time used in the 1970s and is still considered as the base language of programming language.
C is considered a very basic programming language. Any good programmer with C, concepts must learn other languages such as Java, Python, C#, etc.
What is a C Compiler
C compiler is software that converts human-readable C language code into machine coding that can applied with the use of a computer’s central processing unit (CPU). There are many C compilers exits like GCC, Microsoft Visual C++ compiler Clang TinyCC

Features of C Language
- The simple syntax and structured method help C language to easily learn.
- C is a high-speed programming language since it is a static programming language that is faster as compared to languages such as JavaScript and Python. C is compiler-based which is the main feature for high-speed code compilation and execution.
- This language also has features for wiring code when and running it anywhere over the computer. It shows machines not based on C language.
- C is a low-power memory management system offered with the use of a pointer and different functions such as realloc(), free(), etc.
- It also has a pointer that helps to get memory access. It can start pointers like arrays, variables, etc.
- C also offers features such as programming in a structured way that helps to code for different components that use functions stored in libraries.
Data Types in C
Primitive Data
- Primitive data types are very basic data types that are used for denoting basic values like integers floats and characters.
User Defined Data Types
- These types of data are defined by users.
Derived Types
- The data types are derived from other data types like primitive data types are called Derived Data Types
Data Type | Size (bytes) | Range |
Format Specifier
|
short int | 2 | -32,768 to 32,767 | %hd |
unsigned short int
|
2 | 0 to 65,535 | %hu |
unsigned int | 4 | 0 to 4,294,967,295 | %u |
signed char | 1 | -128 to 127 | %c |
unsigned char
|
1 | 0 to 255 | %c |
float | 4 | 1.2E-38 to 3.4E+38 | %f |
double | 8 | 1.7E-308 to 1.7E+308 | %lf |
long double | 16 | 3.4E-4932 to 1.1E+4932 | %Lf |

Expressions and Operators in C
Symbol
|
Operator | Syntax |
+ | Plus | a + b |
– | Minus | a – b |
* | Multiply | a * b |
/ | Divide | a / b |
% | Modulus | a % b |
+ | Unary Plus | +a |
– | Unary Minus | -a |
++ | Increment | a++ |
— | Decrement | a– |
Structs in C
The structure of C language is called Strcuts a method for grouping related variables in a single point. Every variable in the structure is called a member of the structure. Contrary to an array the structure comes with different data types (int, float, char, etc.).
Arrays in C
The array in C is a fixed-size collection of the same types of data stored in contiguous memory points. It is used for storing collection of primitive data types like int, char, float, etc., and operated and user driver data types for example pointers, structures, and dynamic arrays.
Pointers in C
The pointers of C languages are defined as variables that come with the addresses of different variables of the same data types. A pointer is used for accessing the memory of variables and then manipulating their addresses in a program.
Structures and Unions in C
For C programming structure and union are user-defined data types that come with different members of data types. Unions handle memory effectively while structures are used when needed to store distinct featues of the same memory region.
Stacks, Queues, and Linked Lists
Stackis data structured that is according to LIFO (LAST IN FIRST OUT).
The queue is the type that works based on FIFO or (FIRST IN FIRST OUT). In general, Stacks and Queues are applied with the use of Arrays and Linked Lists.
Difference between C and C++
C Language
- C is a procedural programming language.
- It not support the function overloading
- It not support operator overloading
- C does not support data hiding that causes security issues
CPP
- C++ is a procedural and object-oriented programming language.
- It supported function overloading
- Operator overloading is also comfortable with C++
- Data hiding is also supported with this language
What is the basic knowledge of C programming?
- C programming is a structured programming language that is configured with functions and modules and compatible features like loops, conditional, and pointers. It is called compiled language which shows that a program written in C is converted into machine language by a compiler before being executed.
What is C programming language used for?
- C has consistent, simple, and high-power interfacing features. So it is used for making system software, applications software, and embedded systems. The C programming language is highly influential and it helps to drive some other languages.
What is the basic C structure?
- The structure of the C language comes with 6 important parts. They are the document part, link part, definition part, and global declaration part main () function.
How many data types are in C?
- There are 4 types of data types for C programming Char, Int, Float, and Double. For this programming signed modifiers denoted both positive and negative values and unsigned modifiers is positive values.
What is the main function in C?
- The C program comes with basic functions that must have a name. The main work starts with program execution. It comes with program applications through directions to call other functions in the program.
