It's been about a week and I still haven't gotten any respoens, so I'll
try asking once more. I'm having a problem with code similar to the
following. The whole problem is when I set int number = 996546 it works
great, but when int number = 888888 it gives the wrong value.

I would very much appreciate any help.

#include <fstream.h>
#include <iostream.h>

int main(){

        char text[26];
        int number;

        for(int x = 0; x < 25; x++)
                text[x] = (x % 10) + '0';
        text[25] = '\0';

        number = 888888;

        cout << "Before going through the file : " << endl;
        cout << text << endl;
        cout << number << endl;

        fstream file;

        file.open("data", ios::out);
        file.write(text, sizeof(text));
        file.write((char *) &number, sizeof(number));
        file.close();

        text[0] = 'N';  //  TO SHOW IF THE STUFF IS ACTUALLY GETTING READ
        text[1] = 'o';  //
        text[2] = 'p';  //
        text[3] = 'e';  //
        text[4] = '!';  //
        text[5] = '\0'; //
        number = 0;     //

        file.open("data", ios::in);
        file.read(text, sizeof(text));
        file.read((char *) &number, sizeof(int));
        file.close();

        cout << "After going through the file : " << endl;
        cout << text << endl;
        cout << number << endl;
        return(0);
        }
