c++ - 无符号大整数计算器

Question

C++编译器自带的四则运算对于数据的范围是有要求，对于位数很高的数据的四则运算就无能为力，例如，12378456179787565453232321218784545121123132121132178767655657与11231548785127851的和。
请用设计一个类完成无符号大整数的四则运算，加减法是必须实现的，乘除法选做。
【】最大的问题就是进位那地方的代码，感觉很乱，确实不会
谢谢各位了

Answer 2

The first thing to solve is the storage method of large numbers. The options are: 1). Store as strings; 2). Store as linked lists...

There is a question on Leetcode about adding large numbers stored in linked lists, for reference.

You can find many references in the corresponding discussion:

Subtraction of large numbers, or problems of large numbers stored in strings, can be solved similarly.
