Consider the following code, you find what is special about it?

 

 This code defines overloaded functions, so the two function names inside the same output, but the results are not the same as running.

 

Write a method, using the above algorithm to generate a random integer to specify the number (such as 1000) of.

 

 

Modulus = 231-1 = int.MaxValue Multiplier = 75 = 16807 C = 0 when the number of displayed through 231-2, it may be repeated.
