Answer 1

When you use the >> operator, cin reads up until the next whitespace character, but it doesn't process the whitespace. So when you have

std::cin >> str1;
std::getline(std::cin, str2);

the second call will just process the newline character, and you won't have a chance to type in any input.

Instead, if you're planning to use getline after an operator >>, you can call std::cin.ignore() to eat the newline before you call getline.

Edit: it works as you expected when you do

std::cin >> str1;
std::cin >> str2;

since the second call will ignore all leading whitespace.
