C C + + (eight) file stream operation

The standard C library API is provided under the Linux platform to read and write files, and C + + also provides its own means for file stream operation. Although I do not know whether it will be used later, but it is necessary to understand.

Source:

#include <iostream>
#include <fstream>

using namespace std;

int main (void)
{       char filename1[256],filename2[256];
        cout<< "Input source file name:  ";
        cin>>filename1;
        cout<< "Input destination file name:  ";
        cin>>filename2;
        Ifstream infile (filename1);
        Ofstream outfile (filename2);
        char ch;
        while (Infile.get (CH))
                outfile.put (CH);
        Infile.close ();
        Outfile.close ();

        return 0;
}

In C + + to implement the operation of the file stream, you need to include the header file "include <fstream>". This program needs to copy the contents of a file into another file, for example, we have an existing file called Source.txt, which has the following content:
