C++ file read endfinte loop
Author
How can I make a file be read from begining to end and back again tell I exit the program? I want to display the text in a file continusley.
Like say I load a txt file I read its contents from top to bottom but then I want it to start at the top again ect tell I exit the program.
Which part are you having difficulty with?
bool quit = false;do{ /* print file */ if( /* check input */ ) quit = true;}while( !quit );

this is an inner loop so I have to use the if statment but I kind of figured this should work but its not displaying anything at all
if(!dataFile.eof()){ dataFile.getline(fileInput,TSize); cout<<fileInput;} else { dataFile.clear(); dataFile.seekg(0L,ios::beg); }
Read the file once, store it's content in memory, and then display that ad infinitum. Accessing memory is more efficient than accessing the hard-drive.
That may not be an issue for a small toy program, but it's something to keep in mind for real-life scenario's. Just saying. ;)
