The result for the given code snippet is i = -2, j = 3, k = 0, m = 1

Cud u please explain how u get this result?

i is incremented, j is incremented, and both are not 0 (true), so k is not incremented. You're mixing two things that confuse beginners greatly (short circuiting and prefix/postfix side effects). It'd probably be better to break it down a little more until you're more comfortable.

m = 0;
i++;
j++;
if (i != 0 && j != 0)
{
++k;
if (k != 0)
m == 1;
}

but that is a contrived example. Apparently some wikipedia nabob trying to show how clever they are by making a convoluted expression.

i can't see how it has any real learning value. no one will understand the example until after they already understand precedence, and using it to explain precedence will only serve to confuse the beginner.

m = 0;
i++;
j++;
if (i != 0 && j != 0)
{
++k;
if (k != 0)
m == 1;
}

Not quite. k is only incremented if the AND expression fails, not when it succeeds. If the AND succeeds and the OR isn't evaluated, m still needs to be set to true. In your example it remains zero if the AND succeeds.

This is a closer match to the functional behavior:

/* m = ++i && ++j || ++k; */
++i;
++j;
if (i != 0 && j != 0)
{
m = 1;
}
else
{
++k;
if (k != 0)
{
m = 1;
}
else
{
m = 0;
}
}

no one will understand the example until after they already understand precedence, and using it to explain precedence will only serve to confuse the beginner.

Need some help with this Array. I am trying to get the sum of the even numbers and the sum of the odd numbers using a for each loop. I know the answers to what I am trying to achive are sum of even = 84 and the sum of ...

When I execute this progammatically, I get a table with row heights much larger than when I do this manually.

Note : Sel is the Word.Selection object and the Clipboard contains an Excel Table.

public void AddClipboard()
{
Sel.PasteExcelTable(false,false, false);
var t = Sel.Tables[Sel.Tables.Count];
t.AutoFitBehavior(Word.WdAutoFitBehavior.wdAutoFitContent);
}

I have a 2d matrix with dimension (3, n) called A, I want to calculate the normalization and cross product of two arrays (b,z) (see the code please) for each column (for the first column, then the second one and so on).
