    Unhappy Go to the begining of file by same pointer

    if i write c++ like this code, write the value to file.
    Then,how can i set the pointer back to the beginning of file that i have just written it.

    #include <iostream>
    #include <fstream>
    using namespace std;
    int main()
    	int a = 10;
    	fstream aTa("Data_Check.txt",ios::out);
    	for(int i=0;i<a;i++0)
    		aTa << i;
    	return 0;

    For writing, use seekp.

    aTa.seekp( 0, ios_base::beg );
    For reading, use seekg.
