How to randomly generate integers with a specified number of digits?

What does it mean? If you want to generate random integers ranging from N to N + M-1, just let
result = rand ()% M + N
If you want to generate random two digits,
result = rand ()% 100

srand (time (NULL));
iRand1 = rand ()% 100;
iRand2 = rand ()% 1000;

1 digit is (0, 10)
2 digits (10,100)
...
N digits (100 ... 0 (N-1 0), 100 ... 0 (N))
