算法与数据结构练习

设计一个表示分数的类Fraction。这个类用两个int类型的变量分别表示分子和分母。这个类的构造函数是： Fraction(int a, int b) 构造一个a/b的分数。这个类要提供以下的功能： double toDouble(); 将分数转换为double Fraction plus(Fraction r); 将自己的分数和r的分数相加，产生一个新的Fraction的对象。注意小学四年级学过两个分数如何相加的哈。 Fraction multiply(Fraction r); 将自己的分数和r的分数相乘，产生一个新的Fraction的对象。 void print(); 将自己以“分子/分母”的形式输出到标准输出，并带有回车换行。如果分数是1/1，应该输出1。当分子大于分母时，不需要提出整数部分，即31/30是一个正确的输出。注意，在创建和做完运算后应该化简分数为最简形式。如2/4应该被化简为1/2。
