bitmap??

[grando]

hi guys again!
i want to read a bitmap in this way:
please help me!! how can i read the pixels of a bitmap??

#include <iostream>
#include <fstream>
#include <conio.h>
using namespace std;
struct bitmap{
    int pixel;
    int black;
    int white;
};
int main(){
    bitmap b[400];
    ifstream a("a.bmp",ios::binary);
    int i=0;
    while(i<400){
    a.read((char *)&b[i].pixel,24);
    i++;
    }
    i=0;
    int x=0;
    while(i<400){
        cout<<b[i].pixel;
        x++;
        if(x==20)
            cout<<endl;
        i++;
    }
    getch();
    return 0;
}

just replace your own 24-bit bitmap and see the reasult!
is it working?
