设计一门编程语言，给出基础语法代码示例，SDK设计。

一、编程语言设计

1.1 语言名称

本文编程语言的名字叫做“Mango”，这个语言的设计理念是“简洁，易用，可读性强”。

1.2 数据类型

Mango语言支持以下基本数据类型：

• 布尔类型：true、false
• 整型：integer
• 浮点型：float
• 字符串：string
• 数组：array

1.3 基本运算符

Mango语言的基本运算符有：

• 算术运算符：+、-、*、/、%
• 比较运算符：>,<,<=,>=,==,!=
• 逻辑运算符：&&,||,!

1.4 控制语句

Mango语言的控制语句有：

• if语句：

  if(condition){//do something
  }
  

• for语句：

  for(int i=0; i<10; i++){//do something
  }
  

• while语句：

  while(condition){//do something
  }
  

二、SDK设计

Mango语言的SDK包括以下几部分：

2.1 基础库

基础库包括：

• 数学函数库：提供常用的数学函数，如sqrt，max，min等；
• 日期时间库：提供日期时间相关函数，如获取当前时间，比较时间差等；
• 文件处理库：提供文件处理函数，如文件读写，创建目录等；
• 网络处理库：提供网络处理函数，如http请求，socket编程等；
• 字符串处理库：提供字符串处理函数，如字符串拆分，替换，正则表达式等；
• 数据结构库：提供常用数据结构，如栈，队列，哈希表等。

2.2 第三方库

Mango语言支持第三方库的引入，可以自行扩展和安装第三方库，提供更多功能。

三、例子

下面是一个使用Mango语言计算圆的面积的例子：

# 定义圆的半径
r = 3
# 计算圆的面积
area = 3.14 * r * r
# 输出计算结果
print("圆的面积为：" + area)

输出结果为：

圆的面积为：28.26

用 Mango 这门语言实现斐波那契数列。

Mango 是一个用于程序设计的编程语言，它是一种面向对象的编程语言，支持多态、继承、异常处理等特性。它的语法和 Java 语言非常相似，可以让程序员快速上手。

基础语法代码示例

Mango 语言的基本语法如下：

// 定义变量
var x = 10;// 定义函数
func doSomething() {// 函数内容
}// 定义类
class MyClass {// 类内容
}// 定义接口
interface MyInterface {// 接口内容
}// 定义循环
for (var i = 0; i < 10; i++) {// 循环内容
}// 定义判断
if (x == 10) {// 判断内容
}

SDK 设计

Mango 语言的 SDK 支持以下功能：

• 模块管理：支持模块加载，模块初始化，模块卸载。

• 编译器：支持 Mango 语言的编译，支持多语言的编译，如 Java、C、C++ 等。

• 调试器：支持对 Mango 语言的调试，支持断点调试，支持多进程调试。

• 运行环境：支持 Mango 语言的运行，支持多平台的运行，如 Windows、Linux、Mac OS X 等。

使用 Mango 语言实现斐波那契数列

斐波那契数列是一个递归定义的数列，其定义如下：

F(1) = 1
F(2) = 1
F(n) = F(n - 1) + F(n - 2)

使用 Mango 语言实现斐波那契数列，代码如下：

// 斐波那契数列
func fibonacci(n int) int {if (n <= 2) {return 1;}return fibonacci(n - 1) + fibonacci(n - 2);
}// 测试代码
for (var i = 1; i <= 10; i++) {println("F(" + i + ") = " + fibonacci(i));
}

输出如下：

F(1) = 1
F(2) = 1
F(3) = 2
F(4) = 3
F(5) = 5
F(6) = 8
F(7) = 13
F(8) = 21
F(9) = 34
F(10) = 55

总结

Mango 是一门用于程序设计的编程语言，它的语法和 Java 语言非常相似，可以让程序员快速上手。Mango 语言的 SDK 支持模块管理、编译器、调试器、运行环境等功能，通过它可以实现斐波那契数列的程序。

desgin a programming language Mango, with oop and fp style, basic syntax, data types, control flows , and give me example codes.

Mango is a programming language designed to combine the best of both object-oriented programming (OOP) and functional programming (FP) styles. It has a simple syntax, a variety of data types, and powerful control flow capabilities. In this article, we will explore the basics of the Mango language and provide example code snippets to illustrate its features.

Syntax

Mango has a simple, C-like syntax. It is designed to be easy to read and understand, while still providing powerful features. Here is an example of a simple Mango program:

// Hello World programfunc main() {print("Hello World!");
}

Data Types

Mango supports a variety of data types, including integers, floats, strings, booleans, and objects. Here is an example of how to declare and use each type:

// Declaring and using data types// Integer
int x = 10;// Float
float y = 3.14;// String
string z = "Hello World!";// Boolean
bool a = true;// Object
object b = {name: "John", age: 25};// Accessing object properties
print(b.name); // prints "John"
print(b.age); // prints 25

Control Flow

Mango provides powerful control flow capabilities, including conditionals, loops, and functions. Here is an example of how to use conditionals and loops in Mango:

// Using conditionals and loops// If statement
int x = 10;
if (x > 5) {print("x is greater than 5");
}// For loop
for (int i = 0; i < 10; i++) {print("i is: " + i);
}// While loop
int y = 0;
while (y < 10) {print("y is: " + y);y++;
}

Functions

Mango also supports functions, which allow you to create reusable blocks of code. Here is an example of how to declare and use a function in Mango:

// Declaring and using a function// Declaring a function
func add(int x, int y) {return x + y;
}// Calling a function
int result = add(2, 3);
print(result); // prints 5

Conclusion

Mango is a powerful programming language that combines the best of both object-oriented and functional programming styles. It has a simple syntax, a variety of data types, and powerful control flow capabilities. With Mango, you can create powerful and efficient programs quickly and easily.

use Mango write fibonacci function

The following code snippet shows an example of how to write a Fibonacci function in Mango:

func fibonacci(n) {if (n <= 1) {return n;}else {return fibonacci(n-1) + fibonacci(n-2);}
}

Syntax

Mango has a simple syntax that is easy to learn and use. It uses indentation to denote blocks of code, and uses curly braces to denote the start and end of a block.

Data Types

Mango has a variety of data types, including primitive types (such as integers and strings), objects, and arrays.

Primitive Types

Mango supports the following primitive types:

• Integer
• Float
• String
• Boolean

Objects

Objects are collections of related data and functions. They are defined using the class keyword, and can contain properties and methods.

Arrays

Arrays are collections of data that can be accessed using an index. They are defined using the array keyword, and can contain any type of data.

Control Flow

Mango has powerful control flow capabilities, including conditionals, loops, and functions.

Conditionals

Conditionals are used to control the flow of a program based on a given condition. Mango supports the following conditional statements:

• if
• else if
• else

Loops

Loops are used to repeat a block of code until a given condition is met. Mango supports the following loop statements:

• for
• while
• do while

Functions

Functions are used to encapsulate a block of code and make it reusable. Mango supports the following function statements:

• func
• return

Example

The following code snippet shows an example of how to use the Mango language to calculate the factorial of a given number:

func factorial(n) {if (n <= 1) {return 1;}else {return n * factorial(n-1);}
}
