Using string instead of int to make a Factorial, as int has a limit and will overflow if the factorial gets too big
Using string we will have a problem if we run out of RAM, using the number to multiple by ones, tens, hundreds, ...
Similar to how we multiple by hand
You can compile the largeNumberFactorial.cpp or use the executable, if compiling please use c++14 or above After running the executable/compile and run, just type in the number you want the factorial and it will output the factorial
