I really don't know what you mean. Do you want to save integers to file? Binder?

[Sawamura]

i mean that i want to record some data from array to Dat File (ex int.DAT) and the type of file is integer.
ok.please help me i really confused.

Link.

Pay special attention to the section on "Reading and Writing Complex Data". You are interested in integers, but the same principles apply. Here's their example using int instead of Data.

#include <fstream.h>
    ...
    int x;
    int *y = new int[10];

    fstream myFile ("data.bin", ios::in | ios::out | ios::binary);
    myFile.seekp (location1);
    myFile.write ((char*)&x, sizeof (int));
    ...
    myFile.seekg (0);
    myFile.read ((char*)y, sizeof (int) * 10);

Good luck.

this following code to save int file into DAT file :

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

void main ()
{
	int data[] = { 23, 456, 678, 2314, 20, 56, 30981};
	cout<< "Record Data...." <<endl;
	ofstream file_data("INT.DAT", ios::binary);
	for (int i = 0;i < (sizeof(data)/sizeof(int)); i++)
		file_data.write((char *) &data[i], sizeof(int));
	file_data.close();
}
