values between 2 and 105

Is that "between"
inclusive [2,105] as in 2<=x<=105, std::uniform_int_distribution<int> distribution(2,105); or
exclusive (2,105) as in 2<x<105, std::uniform_int_distribution<int> distribution(3,104);?

Either way, it is not rand() % 100,
as in std::uniform_int_distribution<int> distribution(0,99);

Well spotted! I didn't read the description. Code changed above for inclusive.
