Using code:
int main() {
string const a = "1234";
string const b = a;
// outputs the same address for COW strings

}
The above snippet prints the same address on my GCC, because the u...
What is the difference between loose coupling and tight coupling in the object oriented paradigm?

It would be better if you changed the design of your car so that it will work with any engine, so that it is a bit m...

...换为Double类型存储。
但是，取出来的数据（原数据为0.12345）可能是类似0.1234499999999的形式，ToString("f4")转化string值为0.1234，正确值应为0.1235。
解决方法：
先还原Double类型后值为0.12345，再做四舍五入。
