    Angry HELP! My rand() won't make a random number...

    Look at my code:

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include "D:\Dev-Cpp\klib.h"// My libary
    
    int main()
    {
        int nums;
        nums = (rand() % 4);
        
        printf(" %d\n", &nums);
        
        end(); // My function
        return 0;
    }
    and here what it prints:
    7601636

    Where did it get that? Plz Help

    >>printf(" %d\n", &nums);
    should be
    >>printf(" %d\n", nums);

    Also, read this if you want help on generating random numbers.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    Code:
    #include <time.h>
    
    // and add this to the start of main( )
    srand( time( NULL ) );
    Naturally I didn't feel inspired enough to read all the links for you, since I already slaved away for long hours under a blistering sun pressing the search button after typing four whole words! - Quzah
