两个字符串如何赋值

在编程中，两个字符串的赋值通常意味着将一个字符串的内容复制到另一个字符串变量中。以下是在几种不同的编程语言中如何进行字符串赋值的示例：

Python

```python

str1 = "Hello"

str2 = str1

```

Java

```java

String str1 = "Hello";

String str2 = str1;

```

C

```csharp

string str1 = "Hello";

string str2 = str1;

```

JavaScript

```javascript

let str1 = "Hello";

let str2 = str1;

```

C++

```cpp

include

include

int main() {

std::string str1 = "Hello";

std::string str2 = str1;

return 0;
