Getting big random numbers in C/C++

You can easily do this with std::uniform_int_distribution<unsigned long long>. Simple example code (taken from here, modified to use unsigned long long): #include <random> #include <iostream> int main() { std::random_device rd; std::mt19937 gen(rd()); std::uniform_int_distribution<unsigned long long> dis(lowerBorder, upperBorder); for (int n=0; n<10; ++n) std::cout << dis(gen) << ‘ ‘; std::cout << ‘\n’; } Note that the … Read more

Java equivalent of unsigned long long?

Starting Java 8, there is support for unsigned long (unsigned 64 bits). The way you can use it is: Long l1 = Long.parseUnsignedLong(“17916881237904312345”); To print it, you can not simply print l1, but you have to first: String l1Str = Long.toUnsignedString(l1) Then System.out.println(l1Str);
