Hey I'm trying to write a file that opens a text file of the user's choice and stores it (it is assumed to be a list of short strings, such as names) to a vector, each line being in its own index. The user is then able to insert a line, delete a line, and then ultimately save their modified version of the file as a .txt.
The problem is, whenever I run the program, I get this error report:
"Program 17.exe has encountered a problem and needs to close. We are sorry for the inconvenience."
Here is the part of my code that I believe is not executing correctly:
if (myfile.is_open ())
{
while (getline(myfile ,names[line]))
{
line++;
}
etc
}
I have all the appropriate headers (iostream, cstdlib, fstream, string, iomanip, vector).
Thanks in advance.

It doesn't look like you are checking for the end of file - you are using getline to check if the file keeps going. Maybe you should use the .eof() function to control the loop?

Hi all,
I have a web application in which I have to open a "chm" file that

But I do not exactly know the Response.ContentType for chm files.
I have used the following code to handle the case for chm files

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
