<p>int家有i1和i2弟兄俩,小手一拉i1+i2,加起来了;double家有d1和d2姐妹俩,小手也一拉,d1+d2,也加起来了。C++村子里来了复数(Complex)一家子,也有俩兄弟c1和c2,想要来个累加,笨乎乎地,c1.add(c2)。c1和c2伤心极了,也想像其他小朋友一样,小手一拉,c1+c2,也能加起来。这个任务交给了正在看题的魔术师,帮他们一个忙,让复数也能用+号相加吧。(可以复制提示部分的代码开始你的编程)</p> <p></p>
<p>编写基于对象的程序,求长方柱(Bulk)的体积。数据成员包括长(length)、宽(width)、高(heigth)、体积,要求用成员函数实现下面的功能:<br /> (1)由键盘输入长方柱的长、宽、高;<br /> (2)计算长方柱的体积(volume)和表面积(areas);<br /> (3)输出这长方柱的体积和表面积。</p> <p>(可以复制提示部分的代码开始你的编程)</p> <p></p>
