Explanation cin

[Day Vide]

Can you guys explain what the difference is ? Thanks

  std::getline(std::cin, input);

  std::cin >> input;

getline reads from the input buffer till it encounters a newline character(by default, can be changed).
cin on the other hand reads input till a whitespace character is met.

Oh ok thanks mate

Remember cin >> first ignores leading whitespace, but getline does not.

[boost lexical cast]

Also, std::getline() is better for strings.
