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.
Code:#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; }
