# C++ 程序：連接兩個字符串 > 原文： [https://www.programiz.com/cpp-programming/examples/concatenate-string](https://www.programiz.com/cpp-programming/examples/concatenate-string) #### 在此示例中，您將學習連接（連接）兩個字符串（字符串對象和 C 樣式字符串）。 要理解此示例，您應該了解以下 [C++ 編程](/cpp-programming "C++ tutorial")主題： * [C++ 數組](/cpp-programming/arrays) * [C++ 字符串](/cpp-programming/strings) * * * 您可以使用`+`運算符在 C++ 中連接兩個字符串對象。 * * * ## 示例 1：連接字符串對象 ```cpp #include <iostream> using namespace std; int main() { string s1, s2, result; cout << "Enter string s1: "; getline (cin, s1); cout << "Enter string s2: "; getline (cin, s2); result = s1 + s2; cout << "Resultant String = "<< result; return 0; } ``` **輸出** ```cpp Enter string s1: C++ Programming Enter string s2: is awesome. Resultant String = C++ Programming is awesome. ``` 您可以使用`strcat()`函數在 C++ 中連接兩個 C 樣式的字符串。 * * * ## 示例 2：連接 C 樣式字符串 ```cpp #include <iostream> #include <cstring> using namespace std; int main() { char s1[50], s2[50], result[100]; cout << "Enter string s1: "; cin.getline(s1, 50); cout << "Enter string s2: "; cin.getline(s2, 50); strcat(s1, s2); cout << "s1 = " << s1 << endl; cout << "s2 = " << s2; return 0; } ``` **輸出** ```cpp Enter string s1: I love Enter string s2: C++ programming s1 = I love C++ programming s2 = C++ programming ```
