This is a thread containing a problem similar to my previous thread"a crazy problem(at least to me)".
Yet i start it in a new thread is because the approach will surely be much more complicated and perhaps should be treated as another crazy problem.
This program should read in 2 input extremely large postive integers. It will then output their product.
However , as C++ got limit in int, i need to use string variables to represent the values..then use some loops to get pairs of digits first multiplied then add up together.
please stick to my suggestions and avoid showing me some higher levels techs or new libraries. It should be a very challenging one.
ALSO, DON'T PUT DOWN EXACT CODE EVEN IF YOU HAVE DONE THIS BEFORE. JUST GIVING HINTS, GUIDES OR IDEAS WILL ALREADY MAKE ME FEEL VERY GRATEFUL .
