If purely in order to meet the topic request, from the code it's nothing serious, just score will not be 100, random. NextInt (100); To the random. NextInt (101);

Well I think should have no problem in 100

CodePudding user response:

Not to say that your code problem, it is said you random scores no 100
The random nextInt (100); Good return value, 0 to 99, not including 100
