Answer 1

这个还需要算法？自己定一个就可以，比较流行的：rank*rank*10，比如1级需要10点，2级40点，3级90点，4级160点。

Answer 2

对啊，直接switch就可以了。或者用for来判断

Answer 3

        private void button1_Click(object sender, EventArgs e)
        {
            textBox3.Clear();
            int j=100;
            for (int i = 0; i < 100; i++)
            {
                j = j + (j >> 3) + (j >> 4)+100;
                int n = 100;
                for (int m = 0; m < i / 16; m++)
                {
                    n *= 10;
                }
                j = j / n * n;
                textBox3.AppendText((i+1).ToString()+":"+ j.ToString() + Environment.NewLine);
            }
        }
结果:

Answer 4

HimeTale 你这个方法能反过来吗?就是输入一个数值,然后得到是多少级
