How can i make a shift left operation on a(string 'char)

Question

ex: the string(ahmed) by making shift left(<<3)operation i want to get (ed) only ?!

Answer 1

Just use substr. For your example that will look smth. like this:

string str ="ahmed";
cout<<str.substr(3,2); // this will print ed

The 3 means you start from the 3rd char and you save the next 2 values.
And here you have a general form:

cout<<str.substr(3, name.length() - 3);

This will 'shift' any string with 3 positions. Just replace the 3s with 4s and it will 'shift' with 4 positions.
