tmpvalue |= 8 等于 tmpvalue = tmpvalue | 8；即tmpvalue 按位或上8；就如同 tmpvalue += 8 等于 tmpvalue = tmpvalue + 8 类似；tmpvalue <<= 8的意思是tmpvalue左移八位，a|=b的意思是：a=a|b

在返回值的情况下,对象不会在返回的时候调用一次构造,而后在赋值的时候再调用一次构造,两次构造被合并为一次。 Tfunc(){returnT{};}T value=func(); 在构造函数的情况下,哪怕是多次嵌套的构造函数,根据优化要求,最终只保留一次构造调用。 Tvalue(T(T(T(T(func())); 而在这里,所谓的纯右值,包括了非引用...
