Question

I am trying to read an unknown size string from a text file and I used this code :

ifstream inp_file;
char line[1000] ;
inp_file.getline(line, 1000);

but I don’t like it because it has a limit (even I know it’s very hard to exceed this limit)but I want to implement a better code which reallocates according to the size of the coming string .

Answer 1

The following are some of the available options:

istream& getline ( istream& is, string& str, char delim );
istream& getline ( istream& is, string& str );
