    Do you have any specific questions about the code?

    Please edit your post and wrap your code with code tags:
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    How does c = 3?

    For clarity, rewrite the code without using shorthand (augmented operators).
    		int a = 1;
    		int b = 2;
    		int c = 3;
    		a = a + 5;
    		b = b * 4;
    		c = c + a * b;
    		c = c % 6;
    		System.out.println("a = " + a);
    		System.out.println("b = " + b);
    		System.out.println("c = " + c);
    Then trace values of all the variables on some paper.

    When you get to c = c + a * b; note that multiplication, division, and remainder operators are applied first.
    This means a*b is evaluated first and then added to c.

    The % sign means divide the two numbers and give us only the remainder.

    what the result of c = c + a * b;

    Do you have a PC and a java compiler? Write a small program with that statement in it, compile it and execute it.
    Make sure the values of the variables are not the same and are greater than 1.
    If you don't understand my answer, don't ignore it, ask a question.

    hi

    well if we trace the code then
    a = 1+5 =6;
    b = 2*4 = 8;
    c = 3 + 48 =51;
    c = 51%6 = 3 (since dividing 51 by 6 gives remainder 3)
