"how to implement big int in c++" Code Answer

things to consider for a big int class:

mathematical operators: +, -, /, *, % don't forget that your class may be on either side of the operator, that the operators can be chained, that one of the operands could be an int, float, double, etc.
i/o operators: >>, << this is where you figure out how to properly create your class from user input, and how to format it for output as well.
conversions/casts: figure out what types/classes your big int class should be convertible to, and how to properly handle the conversion. a quick list would include double and float, and may include int (with proper bounds checking) and complex (assuming it can handle the range).
