A good and basic implementation of BigInt class in C++
提问by Bebeoix
I'm looking for a good and basic BigInt class in C++, I find a lot of implementation but most of the time, it's complex implementation for crypto library...
我在 C++ 中寻找一个好的和基本的 BigInt 类，我找到了很多实现，但大多数时候，它是加密库的复杂实现......
By basic, I mean BigInt can deal with BigInt, long long and strings with operator overloading. If I had time, I had done myself but I do not have time to create an entire BigInt class.
基本上，我的意思是 BigInt 可以处理 BigInt、long long 和带有运算符重载的字符串。如果我有时间，我已经完成了自己但我没有时间创建整个 BigInt 类。

Here's one. I haven't used it, but it doesn't look too complex, and it was the first result when I googled "bigint c++".
这是一个。我没用过，但看起来不是很复杂，这是我在google上搜索“bigint c++”的第一个结果。

The simplest library I know of is InfInt. It consists of just one header file. Its usage is fairly simple. Here is a sample code:
我所知道的最简单的库是InfInt。它只包含一个头文件。它的用法相当简单。这是一个示例代码：
InfInt myint1 = "15432154865413186646848435184100510168404641560358";
InfInt myint2 = 156341300544608LL;
myint1 *= --myint2 - 3;
std::cout << myint1 << std::endl;
