How do I read and write integers to a file from an array?

[lordhuh]

me again with my c++ final project. i figured out the rand number thing (thank you planet source code). now im stumed again.

i have a file that store info for an arrayed structure. some is int some is chararcter strings. my c++ class only covered fileio with strings not with integers. how do i go about reading and writing the integers to files. thanks

In most cases you would write an int to a file the same way. What method are you using to write the strings to the file?

Here is just some code I'm going to throw at ya, just to give you an idea of what you could do.


#include <fstream.h>

fstream *File;

struct foobar {
char character;
int x, y;
};

int main(void)
{

foobar *fubar;
fubar->character = 'A';
fubar->x = 1;
fubar->y = 2;

File->open(&quot;test.dat&quot;, ios:ut);
File->write((char *)&fubar, sizeof(fubar));
File->close();

return 0;

}


This might be what your looking for, to write the entire structure to a file at once.
