You could just simply not view messages from people you don't know.

Yes, these work, but part of the utility of the email system is that you CAN get messages from unknown people. I read your email address at some interesting site (slashdot?) and I want to have a one2one conversation with you. So I send you an email. You don't know me from anyone, yet we can have a discussion about something without the entire world being privy to it.
And this is the real bad effect that SPAM has created. We no longer trust strangers.
And pasting a screen shot into a word processing document, then attaching that is not OK? Yes, a little more work, but the benefit is safer Internet use for the rest of us.
Email is Email. HTML is for Web pages. The marriage of the two (Thanks Bill!) makes SPAM more dangerous, lets the email sender track you (via 1x1 images), and makes email messages MUCH larger thereby wasting bandwidth.
Hmmm, I assumed that this would be a person who had not done ANY programming.
I too just jump right into a new language. It is mostly just a different syntax. Actually I try to find out what you cannot do in a new language.
Mind you, I had to take a course to learn OO. And I found out that I had been doing OO anyway, just not in a formal sense. Now I find it hard to do non-OO stuff.
Which is how I started. Then I had to unlearn all the bad habits.
There is nothing wrong with mucking around, but you DO need to learn proper methods. Even just mucking around can be a pain if you are constantly over-flowing buffers, over-writing variables in strange places, making everything global, etc.
Its like driving. Yes any kid can get behind the wheel, but to do it right you need instruction.
The best way to learn how to program is to sit down in front of a computer with a reference handy and dive in!
Yup.
And after many years of doing things which make your applications buggy, hard to maintain, full of "cute" tricks, no security, no comments, you finally start doing things properly.
Yup, dive right in.
The thing about courses is that you learn the importance of doing things in a particular fashion. So you end up with applications which CAN be maintained, ARE secure, and so on.
And this comes from experience. I have been doing application development for more years than I care to remember using over 10 different languages, three of which I am actively using right now. I did just dive in. And when I look at what I wrote many years ago, well, I am glad I am the only one that can see that code.
If you're 45 and your skills and productivity can't compete with someone fresh out of college, you deserve to be fired.
Not quite true.
My skill set allows me to do many things. But, when I was looking for work, the responses I got was "you are too senior" and "this job is too simple for you". There was also the salary difference between a seasoned developer and a newbie. Heck, at the time I would have taken the job at the salary. Thank god things are different now.
Throw in the HR department pechant for versionitis and finding a job was NOT a simple thing.
BTW, versionitis is where you must know the EXACT version of some language or tool, such as JSEE 1.4.1. Never mind that you know 1.4.0. Never mind that you can LEARN. You need to have the exact specific version on all the required languages and tools.

YES!
From K&R (first edition) section 5.3 pointers and arrays, page 93 "In C, there is a strong relationship between pointers and arrays, strong enough that pointers and arrays really should be treated simultaneously. Any operation which can be achieved by array subscripting can also be done with pointers."
And then on page 94 "Rather more surprising, at least at first sight, is the fact that a reference to a[i] can also be written as *(a+i)."
The ONLY limitation between the two methods is that the pointer can be moved around, that is p++, whereas the array variable cannot.
They are NOT the same since you can change the contents of amessage but not necessarily the string pointed to by pmessage.
Yes you can change both. Nothing in the C language definition prevents you from doing that.
Furthermore, you're little hack will not determine equality between amessage and the string pointed to by pmessage, yet they are strings.
First of all, it is not my little hack. Go back and re-read this thread.
Secondly, there are NO strings in C. There ARE arrays of characters, and those arrays must have a 0x0 somewhere in them to indicate the termination of the useful portion of the array. If they do not, then all functions which manipulate or examine these arrays will continue on past the apperant end of the array until they DO encounter a 0x0.
I hate to see people giving bogus programming tips
Yes I agree. But my original reply was that the code WOULD COMPILE, contrary to the parent comment. Not that it was good programming form.
I would modify my original statement "It will even work since most compilers will find all instances of identical strings and equate their locations:" to "It might even work since some compilers will find all instances of identical strings and equate their locations:"

I don't know why Java works that way.
Because in Java a String is immutable, so the compiler only creates one instance of the "hello", then s1 and s2 are references to that one instance.
But the s2 += "llo"; creates a new instance.
When you do s1 == s2 you are comparing references.

It might compile, but it wouldn't do what you want it to.
No argument there, in most cases. It still depends on the compiler.
If the compiler DOES reuse address space for identical strings, then it WOULD work. If the compiler creates a new address space for every string, then yes, it would always return false.
And in Java, this would not work as it would be comparing objects. It would compile, but would always be false.
