    {

    printf("\n Cannot open the file");

    return;

    }

    printf("\nEnter your name\n");

    gets(str);

    f<<str;

    f.close();

}

void read()

ifstream f("TEXT.txt");

if(!f)

{

printf("\n Cannot open this file");

return;

}

char str[20];

while(!f.eof())

{

  f>>str;

  puts(str);

}
