We know that smart pointer auto_ptr is defined in the C + + standard library, but we seldom use it, because although it can automatically reclaim dynamically opened memory, it does not require the programmer to maintain the dynamically opened memory,

Produce:The constructor is automatically called by the compiler after the object is defined, and the destructor is automatically mobilized by the compiler at the end of the function call (at the end of the scope of the class). Only after the

In this equation A~i represents the number of 1~9, and the different letters represent different numbers.(PS: The formula is: a+b/c+m/n=10, of which, A,b,c are a number, m,n are three digits.) A total of 10 numbers, and these numbers are 1~9. Cannot

The reflection mechanism of Java is cool, just know the name of the class to be able to load the call. This function is very practical, imagine that the user only need to specify the name of the class, you can dynamically bind the type, and only
