There is an automatic conversion from const char* into strings, but the string class does not provide for automatic conversions from C-style strings to objects of type basic_string<char>. The returned C-style string should not be modified, as this could invalidate the pointer to the string,...
A pointer to the c-string representation of the basic_string object's value. charT is basic_string's character type (i.e., its first template parameter).Example 123456789101112131415161718192021222324 // strings and c-strings #include <iostream> #include <cstring> #include <strin...
我们可以用 = 进行赋值操作,== 进行比较,+ 做串联(是不是很简单?)。我们尽可以把它看成是C++的基本数据类型。 C++中对于strinig的定义为:typedef basic_string string; 也就是说C++中的string类是一个泛型类,由模板而实例化的一个标准类,本质上不是一个标准数据类型。 好了,进入正题……… 首先,为了在我...
std::basic_string<CharT,Traits,Allocator>:: constCharT*c_str()const; (noexcept since C++11) (constexpr since C++20) Returns a pointer to a null-terminated character array with data equivalent to those stored in the string. The pointer is such that the range[c_str(),c_str()+size()]...
