# C++ 程序：复制字符串 > 原文： [https://www.programiz.com/cpp-programming/examples/string-copy](https://www.programiz.com/cpp-programming/examples/string-copy) #### 在此示例中，您将学习如何复制字符串（字符串对象和 C 风格的字符串）。 要理解此示例，您应该了解以下 [C++ 编程](/cpp-programming "C++ tutorial")主题： * [C++ 数组](/cpp-programming/arrays) * [C++ 字符串](/cpp-programming/strings) * * * 您可以简单地使用`=`赋值运算符在 C++ 中复制字符串对象。 * * * ## 示例 1：复制字符串对象 ```cpp #include <iostream> using namespace std; int main() { string s1, s2; cout << "Enter string s1: "; getline (cin, s1); s2 = s1; cout << "s1 = "<< s1 << endl; cout << "s2 = "<< s2; return 0; } ``` **输出** ```cpp Enter string s1: C++ Strings s1 = C++ Strings s2 = C++ Strings ``` 要在 C++ 中复制 C 字符串，请使用`strcpy()`函数。 * * * ## 示例 1：复制 C 字符串 ```cpp #include <iostream> #include <cstring> using namespace std; int main() { char s1[100], s2[100]; cout << "Enter string s1: "; cin.getline(s1, 100); strcpy(s2, s1); cout << "s1 = "<< s1 << endl; cout << "s2 = "<< s2; return 0; } ``` **输出** ```cpp Enter string s1: C-Strings s1 = C-Strings s2 = C-Strings ```
