Although it is possible to use the random class to generate stochastic numbers. But it is the system clock seed, so there is a large number of repeated pseudo-random numbers generated.You can use a RNGCryptoServiceProvider() relative true random

Variable-length one-dimensional arraysThe variable-length array here refers to an array that cannot determine the length of the array at compile time, and the program needs to dynamically allocate memory space at run time. The simplest way to

Four types of coercion conversions: static_cast const_cast dynamic_cast reinterpret_cast1, static_castAny type conversions that the compiler implicitly executes can be done by the static_cast display.① is used for the conversion of pointers or
