您可以使用 = 赋值运算符在 C++ 中简单地复制字符串对象。
示例 1: 复制字符串对象
#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
Enter string s1: C++ Strings s1 = C++ Strings s2 = C++ Strings
要在 C++ 中复制 c 字符串，使用
strcpy() 函数。
示例 1: 复制 C 字符串
#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
Enter string s1: C-Strings s1 = C-Strings s2 = C-Strings
