    simple rand() ques.

    Hi
    Please let me know why we are checking i%5 == 0 .Dont understand that bit .

    #include<stdio.h>
    main()
    {
    int i;
    for (i = 1 ;i <= 20 ;i++)
    {
    printf("%10d", 1 + (rand() % 6));

    if (i % 5 == 0)
    printf("\n");
    }
    }

    Thanks for your time and patience .

    % is the modulos operator. It is used here to output a newline character after every 5 iterations of the loop.
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]
