如何防止我的程序打印多余的斜线？

Question

while (stack.is_not_empty()) {
  cout << "/" << stack.pop();
}

Ideally, my output should be: /feb/12/1983

but I'm getting: //feb/12/1983

I don't understand how this could possible print two slashes in the beginning. There is no other code that prints out anything else out.

Answer 1

Have you checked the values that are in the stack? If you print them out one per line you might find an unexpected value such as an empty string.
