Reading all the data from a file

[Gr1m]

I know how to read data from a file using fin using a given amount of variables, but I want to know how to read 'all' the data from the .txt file till the end.

Read to dynamically reallocating container(s), like std::vector.

Alternatively,

std:ifstream inFile{ "text.txt" };
if ( inFile.is_open( ) )
{
	std::stringstream buffer;
	buffer << inFile.rdbuf( );
	
	std::cout << buffer.str( ) << "\n";
}

You don't actually have to check that the file is open before using the rdbuf() trick.

Also, seekg() is only useful on binary files, unfortunately. (They screw up on non-binary...)

If it's a text file, I think the simplest way is std::string::getline()

    std::string AllTextInFile, temp;
    std::ifstream File("1.txt");
    getline(File,temp);
    AllTextInFile=temp;
    while(getline(File,temp))AllTextInFile+="\n"+temp;
