嵌套结构程序通常涉及在一个数据结构内部包含另一个数据结构。以下是一些不同编程语言中嵌套结构的示例:

C语言

嵌套结构定义

```c

struct emp {

int eno;

char ename;

float sal;

struct allowance {

float da;

float hra;

float ea;

} a;

} e;

```

嵌套结构使用

```c

include

int main() {

struct emp e;

e.eno = 1;

strcpy(e.ename, "John Doe");

e.sal = 5000.0;

e.a.da = 1000.0;

e.a.hra = 2000.0;

e.a.ea = 1500.0;

printf("Employee Number: %d\n", e.eno);

printf("Employee Name: %s\n", e.ename);

printf("Salary: %.2f\n", e.sal);

printf("Allowance - DA: %.2f\n", e.a.da);

printf("Allowance - HRA: %.2f\n", e.a.hra);

printf("Allowance - EA: %.2f\n", e.a.ea);

return 0;

}

```

Python

嵌套结构定义

```python

nested_list = [

[1, 2, 3],

[4, 5, 6],

[7, 8, 9]

]

```

嵌套结构使用

```python

for row in nested_list:

for item in row:

print(item, end=' ')

print()

```

Java

嵌套结构定义

```java

class fruits {

String name;

double price;

}

class Basket {

fruits[] fruitsList;

Basket(int size) {

fruitsList = new fruits[size];

}

}

```

嵌套结构使用

```java

public class Main {

public static void main(String[] args) {

Basket basket = new Basket(2);

basket.fruitsList = new fruits();

basket.fruitsList.name = "Banana";

basket.fruitsList.price = 0.5;

basket.fruitsList = new fruits();

basket.fruitsList.name = "Apple";

basket.fruitsList.price = 0.3;

for (int i = 0; i < basket.fruitsList.length; i++) {

System.out.println("Fruit: " + basket.fruitsList[i].name + ", Price: " + basket.fruitsList[i].price);

}

}

}

```

JavaScript

嵌套结构定义

```javascript

let basket = [

{

name: "Banana",

price: 0.5

},

{

name: "Apple",

price: 0.3

}

];

```

嵌套结构使用

```javascript

basket.forEach(item => {

console.log("Fruit: " + item.name + ", Price: " + item.price);

});

```

这些示例展示了如何在不同编程语言中定义和使用嵌套结构。嵌套结构可以使代码更加灵活和可读,有助于组织和管理复杂的数据关系。
