# String::operator+=
|
|
|
|
```cpp
|
|
String& operator+=(const String& other);
|
|
String& operator+=(const char* str);
|
|
String& operator+=(char c);
|
|
```
|
|
|
|
将指定的内容追加到当前 String 的末尾。
|
|
|
|
**参数：**
|
|
- `other` - 要追加的 String 对象
|
|
- `str` - 要追加的以 null 结尾的 C 字符串
|
|
- `c` - 要追加的单个字符
|
|
|
|
**返回：** `*this`，支持链式调用
|
|
|
|
**复杂度：** O(n)，其中 n 为被追加内容的长度。可能会触发重新分配，但均摊复杂度为 O(1)。
|
|
|
|
**示例：**
|
|
```cpp
|
|
#include "XCEngine/Containers/String.h"
|
|
#include <iostream>
|
|
|
|
int main() {
|
|
XCEngine::Containers::String s("Hello");
|
|
|
|
s += XCEngine::Containers::String(" World"); // 追加 String
|
|
std::cout << s.CStr() << std::endl; // 输出: Hello World
|
|
|
|
s += "!"; // 追加 const char*
|
|
std::cout << s.CStr() << std::endl; // 输出: Hello World!
|
|
|
|
s += '?'; // 追加 char
|
|
std::cout << s.CStr() << std::endl; // 输出: Hello World!?
|
|
|
