What is the purpose of the condition given in the while loop While(! Infile.eof())

Question

Given below is the code segment of a file handling program. What is the purpose of the condition given in the while loop
While(! Infile.eof())
{
Infile>> name>>sal>>dept;
Cout<< name<<"\ t"<< saal<<"\ t"<< dept<< endl;
}

Answer 1

I'm not sure but since eof means end of file, so Infile.eof() will not return true until the end of the file is reached so it returns false everytime but the ! operator makes the condition true and the while loop continuously runs.

So it prints the data from the file and when end of file is reached, the Infile.eof() returns true but the ! operator make the condition false and the loop breaks.

Answer 2

it means, if not at the end of file keep looping.
