area( );return sum; }要求(1)从Shape类派生圆类(Circle)、正方形类(Square) 圆类新增数据成员半径(radius) 正方形类新增数据成员边长(a) 圆类和正方形类都有构造函数 修改、显示数据成员值的函数 求面积函数。(2)写出main()函数 计算半径为5.5的圆和边长为9.9的正方形的面积和(必须通过调用total函数计算)...
A circle is the set of all those points in a plane whose distance from the fixed point remains constant. The fixed point is called thecentreof the circle and the constant distance is known as theradiusof the circle. The line segment passing through the centre of a circle and having its ...
A circle is, a set of points equal distrance (radius) from a fixed point (center point) on a plane. Now that we have a set definition for a circle, let's quickly define the variables involved in the formulas of a circle. Area of a Circle (variable:A)is the area within the circle...
