    how we are gaining 42
    You can see the char for an int by casting it to a char: System.out.println((char)42);
    You can see the int value for a char by casting it to an int: System.out.println((int)'*');

    When posting code be sure to wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    my question isn't about cast my question is i trace program my answer was 64
    my question is what is that exactly
    for (;
    !(d[p] >= d[h--]
    &&
    ++h == p++) {}
    my variables are p = 0 and h = 4 , so d[p] equals d[4] , d[4] inclusive 64
    why my answer is 42 why my answer isn't 63 or 64

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.

    Please post a complete program that will compile and execute for testing.
    Make sure the code is properly formatted with indentations to make it readable.

    my question is what is that exactly
    for (;
    It looks like a for statement. See the tutorial: https://docs.oracle.com/javase/tutor...bolts/for.html
    The for statement has 3 parts separated by ;s
    for (initialization;
    termination;
    increment)
    Any part can be empty. The posted code only has the termination part.
    The statement executes until the termination part is false.
    If you don't understand my answer, don't ignore it, ask a question.
