for(int i=0;i<=7*2;i++)
I often do this kind of thing when I have well-known constants in my code (e.g., 7 days in a week, 2 possible bit values) that aren't worth something like:
#define DAYS_ON_WEEK 7
#define BIT_VALUES 2
But I only do this kind of thing for constants that are immutable and extremely obvious to the context (hey, sue me when bits can store something different from 0 and 1).
This way, writing 7*2 can be more readable than 14 and the compiler will output 14, anyways.

It helps to show that a certain "constant value" is made up by other values.
In this case he probably has stored 2 * 7 values in one array or something.

If you are doing to do something like that you should at least put it in parenthesis with a comment attached to it.
for(int i = 0; i <= (7 * 2 ); i++)
{
}
It looks a little crappy but if you could see the code colorization it would look much clearer.
However it would be wiser to do this.
for(int i = 0; i <= (14 ); i++)
{
}
Describe what 14 is.

It is also useful for programmers that can count only up to 10.

A couple of year ago, I worked for a compagny who were making vision sensing application for wood machinery. Their code (in C++) was a lot complicated, with lots of subclassing, and for the worst part of it, almost every options parameters controlling the code sequence were implemented with #if #then to "save some processor time". (The main core of the program was developped in Turbo-Dos like 15 years ago, then ported to Visual 6.0. It's why they used those #if #then...) The code was more than 3 millions line of code!!!
That's it for the introduction. (You may already laugh!!)
But one day, I came across a fonction used to connect a RS232 port.
This is the interesting part inside the fonction :
...some code here
if( strcmp( lpszPortName, "COM1") == 0 );
{
// Connect the COM1 port
...some code here
}
else if( strcmp( lpszPortName, "COM2") == 0 )
{
// Connect the COM2 port
...some code here
}
else
...
So I asked one of the guy who were working there since a very long time, why they didn't corrected that error... He told me "It always worked well before, and the compiler never notified any error so leave it like that..."
Do you know why I found this little error in 3 millions of code lines? Because this sequence was part of a library used in the main program, and because that library had never been recompiled since its first release 10 years before! For some reasons, I just forgot to follow a little "office rule" that was to never recompile all projects in a workspace in a single shot. I did it "oh unfortunately" then the compiler hit that error immediately!!

I had to stare at that for a good 30 seconds before I spotted the bug. Gosh - I need a decent compiler at this time in the morning to help me!

Ok, it took me a while to see the ";" after the first "if". You would have done me a great favor by simply mentioning that in your message. It's funny!
I just wanted to say that I know what you mean. I'm stuck with something similar. Lots of code doing nothing. I can't believe you actually took the time to count the lines of code!  All I can say is that the program I have to work on has about 30000 files of source organized in about 2000 folders.
So, if there were about 400 lines of code per file, that would make a total of 12 million lines of code! However, that's an understatement, since most files have more than 400 lines of code.
When I run into errors like this I think a lot about whether I should fix them or not, since doing so might actually be causing a bug. ) I took up assembly language a long time ago, just because of this. C++ and all other high level programming languages are supposed to be related a great deal to human language. But people say stupid things all the time.

Real nasty ones these; you just read straight over the problem and not notice it 9 times out of 10.

This is a good candidate for the Subtle bugs forum.

Not if they determined "it's not a bug".
|
|
|
|

And believe what? For them, it wasn't a bug, since it always worked "well" before! At first, they tought it was a typing mistake made accidentaly by me until they looked into SourceSafe and agreed that the mistake was there too, since a couple of years before!

well, it did not take me even a minute to spot that. i caught the error as soon as i read that there was an error in the code.

who else sees this and just laughs:
if (whatever == true){
chkBox.Checked = true;
}else{
chkBox.Checked = false;
}

In opposition to my own statement below I would probably do the following in this case.
CallUpdateFunction(chBox.Checked)

if (whatever == true) {
chkBox.Checked = true;
} else {
chkBox.Checked = false;
} else {

Well, this takes that a step farther; not just the test, but the setting of another boolean.
Every once in a while I catch myself doing that and I have to slap my hand.

Its junk.
chkBox.Checked = whatever;

They were trying to beat 4 millions lines of code. It was a goal for them! Guess why I quit the company a couple of weeks after!!
