Call functions c++ (recursion and CIN input)

Question

Why when I call @choosingAction@ function again I have not an offer to input some information by CIN?

void choosingAction(list* &header, list* &tail) {
int choose, age;
string name;
cin >> choose;
switch (choose) {
case(1):
cout << "Input name and age:" << endl;
cin >> name >> age;
addNode(header, tail);
choosingAction(header,tail);
break;
case(2):
cout << 2;
break;
default:
cout << "Incorrect operation, please choose again" << endl << "| Add - 1 | Find - 2 |" << endl;
choosingAction(header,tail);
}
}

Answer 1

Code Playground does not provide an interactive console. All input has to be received prior to code compilation. If you wish to run your code, try repl.it, or codechef, or cpp.sh.

Answer 2

The problem isn't reproducible. It works well on VS and g++ with some modification (changing the type of the arguments to some primitive type). The best guess is, probably there was some left over on the stream from your previous inputted data, therefore, the next prompt got skipped. Using the `std::cin ` without safety functions like `std::cin.ignore()` and `std::cin.clear()` in such cases exposes the input mechanics to some unexpected behaviors. There might be some other possibilities, but they are less likely and there's not enough code to consider them, as well.

ahaha, I know it. I wrote this code to you see it. I did not want to run it here
