why we use "<< " thes signs in cout function?
why we use "<" this sign double in cout function?
cout << thingie is symbolic for "send thingie to cout". cin >> thingie is symbolic for "send something to thingie from cin". The angle brackets denote the direction that data moves.
cout << thingie
cin >> thingie
Whether >> and << are the best symbology for the behavior is up for debate, but it works reasonably well in practice.
please give me an example of cpp program.
