What is the difference between console I/O functions and stream I/O functions?

Question

please help confusion

Answer 1

Console I/O is as it says interacts directly with console or terminal, whichever you use.
Stream I/O are little different.
I'll try to explain it.
Let's say we want to output a string "Hello world". One way is,
cout << "Hello world";
This way can only show output wherever cout is linked to, like console.
Other way can be
string myString =" Hello world";
Now, this is little better. We can use this variable to show it on console,
cout << myString;
Or, write it in a file
ofstream myFile;
myFile.open("file.txt");
myFile << myString;
myFile.close();
Or, write it on ANY other device!
Streams are something like that. You can use them to store some data, and then flush them anywhere you want.
I hope it's a right explanation. Anyone else if has better explanation or corrections, please due share.
