现在公认的几种计算机语言（你应该知道的四门计算机语言）

C is a powerful general-purpose programming language. It can be used to develop software like operating systems, databases, compilers, and so on. C programming is an excellent language to learn to program for beginners.，今天小编就来说说关于现在公认的几种计算机语言?下面更多详细答案一起来看看吧!

现在公认的几种计算机语言

C 语言

每个大学生的必修语言，一切编程语言的基础，简单强大。

C Program to Display "Hello, World!"

#include <stdio.h> int main() { // printf() displays the string inside quotation printf("Hello, World!"); return 0; }

Output

Hello, World!

2 . C

C is a powerful general-purpose programming language. It can be used to develop operating systems, browsers, games, and so on. C supports different ways of programming like procedural, object-oriented, functional, and so on. This makes C powerful as well as flexible.

C （c plus plus）是一种计算机高级程序设计语言，由C语言扩展升级而产生。C 既可以进行C语言的过程化程序设计，又可以进行以抽象数据类型为特点的基于对象的程序设计，还可以进行以继承和多态为特点的面向对象的程序设计。

C "Hello World!" Program

// Your First C Program #include <iostream> int main() { std::cout << "Hello World!"; return 0; }

Run Code

Output

Hello World!

使用命名空间更简单：

#include <iostream> using namespace std; //使用命名空间 int main() { // prints the string enclosed in double quotes cout << "Hello World!"; return 0; }

Run Code

Output

Hello World!

3 .SQL

SQL (Structured Query Language) is a powerful and standard query language for relational database systems. We use SQL to perform CRUD (Create, Read, Update, Delete) operations on databases along with other various operations.

SQL结构化查询语言(Structured Query Language)简称SQL(发音：/ˈes kjuː ˈel/ "S-Q-L")，是一种特殊目的的编程语言，是一种数据库查询和程序设计语言，用于存取数据以及查询、更新和管理关系数据库系统。

4 .Python

Python is a popular general-purpose programming language. It is used in machine learning, web development, desktop applications, and many other fields. Fortunately for beginners, Python has a simple, easy-to-use syntax. This makes Python a great language to learn for beginners.

Python "Hello World!" Program

# This program prints Hello, world! print('Hello, world!')

Run Code

Output

Hello, world!

Python 对初级程序员而言，是一种伟大的语言，它支持广泛的应用程序开发，从简单的文字处理到 WWW 浏览器再到游戏。

Python 之禅：

Beautiful is better than ugly.

Explicit is better than implicit.

Simple is better than Complex.

Complex is better than complicated.

Flat is better than nested.
