Hello Learning Lad thanks for this vid.
You used this code
if(!file.is_open()){
cout<<"error while opening the file.;
}
You could do this in another way.
if(file.fail()){
cerr<<"error while opening the file";
}
Thanks for explaining.
It is better than the book I use to learn c++.

I have a doubt
about how to open a file that exists in a non-working directory
suppose I have my C++ file in path C:/Coding/57th Code/main.cpp
I want to open a file that is in path C:/CS19B005/text folder/hello.txt

Now how can I access file

Fatal error:Fstream.h: no such file or directory
How can we remove this error

You were using the bit wise OR operator '|' instead of using the logical OR operator '||'.
