C++

注意题目给的样例是YYYY-MM-DD（至少看着很像这样）

实际上是以“-”来分割的

	getline(cin, dateS);
	size_t firstDash = dateS.find("-");
	size_t secondDash = dateS.find("-", firstDash + 1);
	date.year = stoi(dateS.substr(0, firstDash));
	date.month = stoi(dateS.substr(firstDash + 1, secondDash - firstDash - 1));
	date.day = stoi(dateS.substr(secondDash + 1));

分割的部分代码如上↑
