以下代码是string构造的几种方法,代码来自std::string::string // string constructor #include #include int main () { std::string s0 (“Initial string”); //根据已有字符串构造新的string实例 // constructors used in the same order as described above: std::string s1; //构造一个默认为空的strin...

This is the default constructor. It creates an empty string. Sample code: std::string sSource;std::cout<<sSource; Copy Output: string::string(const string& strString) This is the copy constructor. This constructor creates a new string as a copy of strString. ...

By making use of C++ concepts such as constructors, destructors, and operator overloading, std::string allows you to create and manipulate strings in an intuitive and safe manner! No more memory management, no more weird function names, and a much reduced potential for disaster. Sign me up...

破案链接:https://stackoverflow.com/questions/54420470/does-stdstring-move-constructor-actually-move 按照移动构造函数的要求,个人理解std::string的移动构造函数应该将参数对象的char* data指针直接赋值给目标对象,然后置为nullptr。从地址来看,目标对象的data指针指向的地址应该和参数对象开始时指向的相同。
