C + + Specifies that the suffix form has an int type parameter, and when the function is called, the compiler passes a value of 0 as the int parameter to the function.The prefix form of the increment means "add and then retrieve", and the suffix

Header file has an important function rand (), which can be used as a random number generator.Now I want to generate a random number, I use the following program:#include #include using namespace Std;int Main () {cout The problem comes, although
