How can i read from file in cpp?

Question

For example when i write: while (!p0.eof()) to read from file the program just reads the first record and shows it?
please see code 6

Answer 1

do you have
p0>>inputElement;
before you re-iterate the loop? if not it would only take in the first one.

#include <fstream>

ifsteam file;
file.open("fileName.txt"); //assuming this text file is in the same directory
//of this file.
int tempInput;
while(!file.eof()){
file>>tempInput;
//do stuff with info
} //goes until end of file.

this should work
