using namespace std;

int main()
{

        char fname[20], ch, choice;
        fstream fps, fpt;

        {
                cout<<"\nError in creating file5.txt file..!!";
                fps.close();
                cout<<"\nPress any key to exit...";

                exit(2);
        }
        while(fps.eof()==0)
        {
                fps>>ch;
                ch=ch+100;
                fpt<<ch;
        }

        fps.close();
        fpt.close();
        fps.open(fname);
        if(!fps)
        {
                cout<<"\nError in opening source file..!!";
                cout<<"\nPress any key to exit...";

                exit(3);
        }
        fpt.open("C:\\Users\\acer\\Documents\\file5.txt");
        if(!fpt)
        {
                cout<<"\nError in opening temp.txt file...!!";
                fps.close();
                cout<<"\nPress any key to exit...";

                exit(4);
        }
        while(fpt.eof()==0)
        {
                fpt>>ch;
                fps<<ch;
        }
        cout<<"\nFile "<<fname<<" encrypted successfully..!!";
