    Question Random Number

    I wanna make the program pick a number randomly between 1 and 15. What's the script for that. Also, how do you assign that number to a varible.

    Thanks!

    Read the faq.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Using the function name from the faq...
    Code:
    int mynum;
    
    mynum = rand_mid(1, 15)
    When all else fails, read the instructions.

    Using the time to seed a random number isn't a bad idea.

    Here is one solution.

    -----
    srand(static_cast<unsigned>(time(0)));

    // random number 1 to 15

    int rNum = static_cast<int>((((static_cast<double>(rand())) / (static_cast<double>(RAND_MAX + 1))) * 15 + 1));

    here..

    simple


    PHP Code:
    #include <stdio.h>   //for printf, etc
    #include <time.h>   //for time function in randomize()
    #include <stdlib.h>  //for randoming functions

    main()
    {
            
    int i;
            
    randomize()
           
            for (
    i=1i<=10i++)
            {
                  
    printf("%d\n"1rand()%15 );
            }
