考查:count++

看看下面这块代码输出的值是多少?

public class Static_Test {
    public static void main(String args[]) {
        int count = 0;
        int num = 0;
        for (int i = 0; i <= 100; i++) {
            num = num + i;
            count = count++;
        }
        System.out.println(count * num);
    }
}

原本我以为是 510050, 实际上

是0.

count == count++;
//VS
count++;
