Writing All ASCII(with Extended 0-255) Character to a Binary file Using C++

The reason I use here binary file because using binary file we can  both read and write easily




#include<bits/stdc++.h>
using namespace std;
int main ()
{
    string s ="";
    fstream file("compress.bin", ios:: binary | ios::in | ios::out | ios:: trunc);
    for(int i= 0; i<256; i++)
    {
        char  c=i;
        file.write((char *)&c,sizeof(c));

    }
}
