C++：获取 MacOS 版本

Question

I need to find a way to find the OS version of a MacOS system, preferably without external libraries. How would that be possible?

I don't have a MacOS machine to be able to test the code.

Compiler: g++

Answer 1

The simplest solution is to do:

#include <sys/utsname.h>

void main() {
    struct utsname uts;
    uname(&uts);
    return uts.release;
}
