    problem with random integer

    hello,

    i want to make a random number between 1, and 10 that is different every time i use it. i want the integer to be called "my_number". here's what i have so far:

    #include <stdio.h>
    #include <stdlib.h>
    #include <time.h>

    int main ()
    {
    int seed = (int)time(NULL);
    srand(seed);
    rand();

    int my_number = 1+(int) (10.0*rand() / (RAND_MAX+1.0));


    could you tell me what is wrong??? thanks so much!!!

    Here is the short code for generating an integer from 1 and 10. I have a better algorithm, but I do not have the source code for it right now because I do not have access to my workstation.

    // Generate an integer between 1 and 10.
    int OneTen = 1 + rand() % 10;
