Following is the syntax for std::istream::getline() function.istream& getline (char* s, streamsize n ); istream& getline (char* s, streamsize n, char delim ); Parameterss − It indicates the pointer to an array of characters where extracted characters are stored as a c-string. n ...
然后回到问题本身，我的答案是「没必要」。反复读入巨型字符串的场景一般都是 IO，内存操作的性能开销在...
其中cin 是正在读取的输入流,而 inputLine 是接收输入字符串的 string 变量的名称。下面的程序演示了 getline 函数的应用: // This program illustrates using the getline function //to read character data into a string object. #include <iostream> #include <string> // Header file needed to use string...
String - Making getline() in C, Making getline () in C. I wanted to make my own getline () like function in C and this is what I came up with: void getstring (char *string) { fgets (string,STRING_LENGTH,stdin); string [strlen (string)-1]='\0'; } It's good enough if num...

A global function with the same name exists in header <string>. This global function provides a similar behavior, but with standard C++stringobjects instead of c-strings: seegetline (string). Parameters s A pointer to an array of characters where the string is stored as a c-string. ...
