So, what it reads is probably a\n but it only shows you the a in the first cout Then, same goes for b\n but again shows you b Cin eats up that '\n', the new line character. Mean in the cout, cin, cerr and clog names I would say char but i haven't found anything to confirm it. Mean in cout, cin, cerr and clog
Can someone please explain to me what cout stands for? More correctly, cin reads from standard input (stdin) This may be the console, but it could also be a file or other device depending on the operator system and redirection by the user. 5 std::cout and std::cin are indeed global variables Your code doesn't compile because that's not the way the language works You have to put the stream on the left, and then the operator and then the variables you are streaming into/out of
3 there is no close equivalent to cin in c However, you can read things in c using the c standard library, you can look at the relevant part here (cstdio reference). Forgive me for possibly asking a fairly simple question, but what does the insertion operator actually mean and do in a program Cout << / cin >>) !cin checks is fail () returns true for the stream Before c++11 this was going through void*, after that it is using bool operator as indicated here
What fail checks is if failbit or badbit are up for the stream and you can read more about them here. However, the result of (cin >> variable) is a reference to cin Therefore we can again use >> in order to get more values from the stream Cin >> n >> g This is equivalent to cin >> n So we now know that cin >> n >> g takes two integer values from the input stream and returns a reference to cin.
