而y= (++x)+ (++x); 这个语句中x被自加了两次，而只有一个语句，也就是说在运行到分号的时候 x的值是6，那么系统在执行y= (++x)+ (++x); 这个时候 认为y = 6+ 6； 结构是等于12. 我实验了一下。 所以我想这个和运算符的 目数是有关系，+ 号是双目运算符。 所以在只有两个数相加的时候系统把两个操作数的++都处理完了 再处理+运算。 而加了括号结果改变就比较好理解，括号优先级高些，先处理括号里面的，所以在括号里面的操作数一同被处理，得到了上面加了括号后的结果 …

将 x^{4}-y^{4} 改写为 \left(x^{2}\right)^{2}-\left(y^{2}\right)^{2}。 可使用以下规则对平方差进行因式分解: a^{2}-b^{2}=\left(a-b\right)\left(a+b\right)。 \left(x-y\right)\left(x+y\right)
