Why does C++ rand() seem to generate only numbers of the same order of magnitude?
... you keep doing this for n, you can see that from 1 to 10^n, 99.9999...% = 100% of the numbers are from 10^0 to 10^n with this method.
Now about code, if you want a random number with random orders of magnitude, from 0 to 10^n, you could do:
Generate a small random number from 0 to n
