建立一個char *的全部價值字符串

Question

我想知道如何設置字符指針值「d」，在「STREN」

char *d; 
std::string Stren = *d; 

Answer 1

單個字符的構造函數需要一個補數。

std::string Stern(1, *d); // Stores a single character pointed by d. 

例如：

char *d = "this is an example"; 
std::string Stern(1, *d); // Stern is now "t"; 
std::string Stern2(d);  // Stern is now "this is an example"; 

std::cout << d << std::endl; // Outputs "this is an example" followed by '\n' 
std::cout << *d << std::endl; // Outputs "t" followed by '\n';
