    Unhappy random in Dev C++ still not working

    Hi!

    I want to use "random" in Dev C++ so that it chooses between two digits 1 and 2. But I don't seem to know how!

    I have tried with

    srand(time(NULL))
    rand() % 2

    but it gives me the numbers 0 and 1. Any one whol could help would be really appreciated.

    Thank You very much!

    If you can get 0 and 1 as random numbers and you need 1 and 2 then have a guess what you need to do. What's the difference between 1->2 and 0->1.

    If you get 0 or 1 then add 1 to the result to obtain either 1 or 2.

    If you were wanting to get a random number between 1 and 2?!?

    then the code would be,

    srand(time(0));
    rand()%2+1;

    You would have to put that with a variable of course
