Input/Output-StreamsOpening Textfiles - ReadWe use the textfile "names.txt" which contains some names: micky mouse morty mouse minnie mouse maxi mouse monti mouse The following program reads all data from the textfile and writes it to the standard output: #include <iostream.h> #include <fstream.h> int main() { char linebuffer[80]; ifstream ifs("names.txt", ios::in); while (!ifs.eof()) { ifs.getline(linebuffer, 80, '\n'); cout << linebuffer << endl; } return 0; } So we get the following output: micky mouse morty mouse minnie mouse maxi mouse monti mouse Creating Textfiles - Write, AppendThe following example demostrates how to append new lines to an existing textfile.
