C from the text to read each line is a struct, and then each line in the vector, the output to the s-CodePudding

Document A, each line is A struct, finally the number of Numbers is not necessarily need to put each line in the vector and then output to the screen, and also exported to the new document B, give advice or comments, thank you!

Struct hero
{
string name;
int age;
Char sex;
double weight;
The string color;
Vector number;
};

Modify the,
While (line. The length () & gt; 0)//& gt; 8 minimum length may be 9, including five fields, 4 Tab characters or Spaces
And, behind the number of uncertain may be zero, changing the while (ss) good ())

Should use the
Istringstream ss (line);
Replace
Istrstream ss (line c_str ());
Header file by strstream into sstream
Better still, use not familiar with impression all mixed up,
