Introduction to C Language

For beginners and professionalsC languageThe tutorial adopts a programming approach that can help you easily understand the C language tutorial. Our C tutorial explains each topic through programs.

C language was developed by Dennis Ritchie to create system applications that interact directly with hardware devices (such as drivers, kernels, etc.).

C programming is considered the foundation of other programming languages, which is why it is called the mother tongue.

C is a powerful general-purpose programming language. It can be used to develop operating systems, databases, compilers, and other software. C programming is an excellent programming language suitable for beginners to learn. Our C tutorial will guide you step by step through learning C programming.

It can be defined as follows:

1. Mother tongue

2. System programming language

3. Procedural programming language

4. Structured programming language

5. Middle-level programming language

1) C as the mother tongue

C language is considered the mother tongue of all modern programming languages becauseMost compilers, JVM, kernels, etc. are written in C, and most programming languages follow the C syntax, such as C ++, Java, C#, etc.

It provides core concepts such as arrays, strings, functions, file handling, etc., which are being used by many languages (such as C ++such as Java, C#, etc.) are used.

2) C as a system programming language

System programming languages are used to create system software. C language is a system programming language becauseCan be used to perform low-level programming (such as drivers and kernels). It is usually used to create hardware devices, operating systems, drivers, kernels, etc. For example, the Linux kernel is written in C.

It cannot be used for Java, .Net, PHP, and other Internet programming.

3) C as a programming language

The process is called a function, method, routine, subroutine, etc. Procedural languageForProgramSpecifies a series of steps to solve the problem.

Programming languages decompose programs into functions, data structures, etc.

C is a procedural language. In C, variables and function prototypes must be declared before use.

4) C as a structured programming language

Structured programming languages are a subset of procedural languages.Structure refers to decomposing the program into multiple parts or blocks,So that it is easy to understand.

In C, we use functions to divide the program into multiple parts. It makes the program easier to understand and modify.

5) C as a middle-level programming language

C is considered a middle-level language becauseSupports both low-level and high-level language features. C language programs are converted to assembly code, which supports pointer arithmetic (low-level), but it is independent of the machine (high-level functionality).

OneLow-level languageIs specific to a machine, that is, dependent on the machine. It depends on the machine and runs fast. But it is not easy to understand.

OneHigh-level languageIs not specific to a machine, that is, machine-independent. It is easy to understand.

C language program

In this tutorial, all C programs are provided with the C compiler, so you can quickly change the C program code for practice.

File: main.c

Example

#include <stdio.h>　　
　　　　int main() {　　
　　　　printf("Hello C Programming\n");　　
　　　　return 0;　　
}

Output:

Hello C Programming
