从 long long 转换为 int 的意外行为

Question

I'm working on VS2019, in windows 10 64bit. I was doing some try and I tried the following code

int main() {
    unsigned long long ull = 70000;
    unsigned int ui = ull;
    std::cout << ui;
}

I would expect to get an output different from 70000, because 70000 is bigger then then the biggest number that an int variable can store. so why do I get 70000 as output? how is that possible?

Answer 1

A 32 bit unsigned int can store values from 0 to 4,294,967,295.
