数据结构中顺序表的初始化怎么用代码实现

在数据结构中,顺序表通常通过数组来实现,其初始化通常是创建一个新的数组并分配足够的空间存储元素。以下是用几种常见编程语言实现顺序表初始化的简单示例:
1. **Python**:
```python
def initialize_sequence_list(length):
sequence_list = [None] * length
return sequence_list
# 使用时,传入所需长度
initial_list = initialize_sequence_list(5)
```
2. **Java**:
```java
public class SequenceList {
private int[] list;
private int size;
public SequenceList(int capacity) {
this.list = new int[capacity];
this.size = 0;
}
}
```
3. **C++**:
```cpp
#include <vector>
using namespace std;
class SequenceList {
private:
vector<int> list;
public:
SequenceList(int capacity) {
list.resize(capacity);
}
};
```
4. **C#**:
```csharp
using System.Collections.Generic;
public class SequenceList
{
private List<int> list;
public SequenceList(int capacity)
{
list = new List<int>();
for (int i = 0; i < capacity; i++)
list.Add(default(int));
}
}
```
上述代码展示了如何分别为列表分配初始容量,并保持默认值(如`default(int)`)。
