Web this tutorial gives the description as well as the steps for programmers to learn how reading and writing binary file in c++ works. These classes are derived directly or indirectly from the classes istream and ostream. To create files and write to existing files, use ofstream. Read the file’s contents into our stream object. // check that array is not already full while (cnt < arr[30] && is >> x) // and read integer from file arr[cnt++] = x; // print the integers stored in the array cout<<the integers are.</p> Web this tutorial gives the description as well as the steps for programmers to learn how reading and writing binary file in c++ works. While (file >> num) { //whatever you need to do } } Consider using argc and argv to allow the user to specify file names on the command line.
