Answer 1

Did you place cnf<<line<<endl; inside the loop as well?

Answer 2

You should put the getline part in a loop to read the entire file. Also, don't close the file before you read everything.

Code Example :
------------------------------------------------------------------

string line;
ofstream cnf("newfile.txt");
while(!readFile.eof())
// While we are not at the end.
{
getline(readFile, line);
cnf <<"Line read from the Good.c file: "
<<line <<endl;
// Read from one and write to other.
}
readFile.close();
cnf.close();
// Close only when done.

Answer 3

A loop is required here, as your file contains multiple lines and you need to have a getline for every single one of them.

Answer 4

I'll try

Answer 5

*** edit:
