利用AFEPack包求解变二次系数的椭圆型方程.在求解这个问题的过程中，先要把程序的结构进行整理，将变二次项系数的因素加进去 ，并使得其更加有利于复杂一些的问题的求解 。为此，我们使用一个类来管理这个求解的问 题，先写一个对这个类进行声明的头文件 EllipticEquation.h-Use AFEPack package for solving variable coefficient elliptic quadratic equation. In solving this problem, the first to organize the structure of the procedure will change coefficient of quadratic terms added to the list of factors, and make it more conducive to the complexity of some of the problem solving. To this end, we use a class to manage to solve this problem, first write a statement of this type for the header files EllipticEquation.h

练习程序，问题如下：进行高精度整数的加、减、乘运算。输入两个十进制大整数M和N（M、N最长可达50位），计算运算结果并输出。【输入形式】标准输入上依次分行输入以下内容：1.第一行输入第一个大整数M。M可能带有负号，后面是最长可达50位的数字序列。2.第二行只有一个字符，可以是“+”、“-”、“*”，分别代表加、减、乘三种运算符。3. 第三行输入大整数N，格式与M相同M、N均不带有前缀的多余的0【输出形式】在标准输出上打印运算结果，输出一行字符序列，是大整数M和N和运算结果。如果该运算结果是正数，则直接输出各位数字序列；如果是负数，则首先要输出负号。各位数字紧密输出，不带有前缀的多余的0。-practice procedures, as follows : high-precision integer for the addition, subtraction, multiplication. The importation of two decimal integer big M and N (M, N up to a maximum of 50), the calculated results of operations and output. Entry forms : standard input on the importation of branches were the following : 1. The first line inputs, a large integer M. M may have negative, is back up to 50 digital sequence. 2. Only a second line of characters could be "","-","*", respectively, plus or minus, by three operators. 3. The third line inputs large integer N, M and the same format M, N are not redundant with the prefix 0 output-- in the form of print on standard out
