I was trying to read a text file of which the character length is 78125 and when I read and count character wise in my C++ program as given below the output was 77500. And for files of total character length greater than the above the output was not actual...
I'm doing this to read a mp3 like large file

C#
#include<fstream>
#include<iostream>
using std::fstream;
using std::ifstream;
using std::cout;
using std::cin;
void main()
{
    char c;
    int i=0;
    ifstream f1("one.mp3");
    if(f1!=0)
    {
    while(f1>>c)
    {
        i++;
    }
    f1.close();
    cout<<"FILE LENGTH "<<i;
            }
    else
        cout<<"File Not Found";
    cin>>c;
}


Thank you

Replace the line

ifstream f1("one.mp3");

with
ifstream f1("one.mp3", std::ios::in | std::ios:binary);

Thank you,...
That's working 99% but not in 1% files......... for some file it returns previous to some data.....
Any way thanks...... but what's that "ios::binary|ios::in" mode means.

ios::binary means to read the file without trying to translate end of line characters. ios::in means the file is accessed for input only. Take a look at the MSDN pages for iostream for more information.
