C++字符串和整型互转

1. int 转string:

int y = 2014;
	int m = 6;
	int d = 23;
	int h = 7;
	int mm = 25;
	char str[20];
	sprintf_s(str, "%04d-%02d-%02d/%02d:%02d", y, m, d, h, mm);
	string s = str;
	cout << s << endl;

2. string 转int:

string s = "2014-10-04/14:30";
	int y, m, d, h, mm;
	sscanf_s(s.c_str(), "%d-%d-%d/%d:%d", &y, &m, &d, &h, &mm);
	cout << y << endl
		<< m << endl
		<< d << endl
		<< h << endl
		<< mm << endl;

其他类型可以通过改变字符串格式化时的参数（%d）来实现字符串和其他类型的转化。
