C++ Read File Until Space

Question

Is there a way I can read data from a file until a space? I have a file

John J. Doe

and I want to read the file and put John in 1 variable, J. in another variable and Doe in a final variable. How do I do this with ifstream?

Answer 1

You can just read the values into std::string variables, this will automatically tokenize it.

std::string fName, middleInit, lName;
my_stream >> fName >> middleInit >> lName;

Answer 2

Is this your file name or file content? I assume it's file content.

#include<fstream>
#include<string>
//..........
ifstream fin;
fin.open("your file", ifstream::in);
string var1, var2, var3;
fin>> var 1 >> var2 >> var 3;
