Converting buffer into data

Hi everybody,

This is what I am trying to do:

I have a:
struct t{
char c[10];
int i;
};

I write this to file e.g. with values c="abcd" and i=1234.

Now I read the entire data back into a buffer buf[16]. And I want to
convert this buffer back into the original data. (I am trying to do
what operating system would do automatically if I had used the same
struct to read the data back in.)

I then parse the buf for those values by copying the data character by
character into another buffer.

I am able to get the character data back.

My problem: I cannot retrieve the integer back. When I do an atoi(),
the value I get is zero.

#include <fstream>
#include <iostream>
#include <string>
using namespace std;

struct t
{
char c[10];
int i;
};

struct v
{
char buf[16];
};

void main()
{
int x=0;

t my;
v your;

my.i=1234;
strcpy(my.c, "abcd");

cout << "size of my: " << sizeof(my) << endl;

fstream f;

f.open("test", ios::out | ios::binary); // first write data to file
f.write((char *)&my, sizeof(my));
f.close();

//now read back in
f.open("test", ios::in | ios::binary);
f.read((char *)&your, sizeof(your));
f.close();

cout << "char " << your.buf << endl;

char temp[10];

// 0 - 9 is character data
for(x=0; x<10;x++) temp[x] = '\0'; // fill in null terminators
for(x=0; x<10; x++)temp[x]=your.buf[x];

cout << "temp character part of my: " << temp << endl;

// 10-15 is integer data (??:not sure)
for(x=0; x<10;x++) temp[x] = '\0'; // fill in nulls
for(x=0; x<6; x++)temp[x]=your.buf[x+10];

cout << "temp int part of my: " << temp << endl;
cout << "atoi : " << atoi(temp) << endl; // should i get back: 1234?
// the result i get for this cout = 0
// i want the integer i originally stored = 1234
}

Thanks for all your help!
