The space is not big deal, but I like consistency and placing that space suggests to me that a space should be place before every ‘(‘ character. When I started programming (in C) using ‘++i’ as apposed to ‘i++’ was a very minor optimization, as the compilers did not do the optimization for you. In C it was not really that important, even when the machines where slow, but is C++ it can make a big difference. As you noted “Most of the time it makes no difference”, but if you make it a habit and teach others to do the same thing, which most books do now, then they are learning the wrong thing. Even Bjarne Stroustrup uses ‘++i’ instead of ‘i++’ although I have never read a statement by him as to why he does that. But other experts on the language have explained it in detail.

as far as if() with or without a space in between i dont care but the difference between "i++" and "++i" is... i++ = returns the value of 'i' before it was incremented ++i = returns the value of 'i' after it was incremented e.g
int i = 1;
if(++i == 2)
{
thisWillWork();
}
//
//OR
//
int i = 1;
if(i++ == 2)
{
thisWontWork();
}This is what the operators do and you can use them bassed on what you need your code to do. if you use them correctly you can end up saving a few lines of code:cool: ps. as to my brace style brace on next line = more readable thats my vote

God of course intended that there be only one bracing style. All other expose one as a programmer who has fallen from the path. The pattern for an 'if' is as follows:
if (conditional) { // waste not, want not: don't waste vertical space
statement(s) // note the indention, this clearly identifies these statements as
// belonging to the if
} // note the indention again, this closes the if logic, it is the
// end of the existing block, not the beginning of a new oneOf course heritics abound, but my place in "code vault store" is assured (ya have to be a fan of STTNG Klingon afterlife to get that one). Go forth and spread the glad tiding and good bracings and do not hesitate to cntl-K cntl-D the code of the unbelievers. ;):laugh: Brace Zealot -- modified at 11:16 Thursday 17th May, 2007
BLASPHEMY!!!!:omg: indenting the closing brace *-Shudder-* u r a Patagh

what about delegates, how do folks brace those? On other things I use brace-on-line, unless I put content on same line eg - case Monday : { DoWork(); break; }. Before I started using IDE's I always used K&R style, but tubes were smaller then, so whether it's IDE's or screen size I dunno,: sigh: could be age philD

Do not fear brother. One day you shall be brought into light, cleansed and purified. Then you can find the true joy known only by those who indent our closing braces. Convert now and do not risk an afterlife protected by Fek'lhr.
MORE BLASPHEMY!!! the true if is as follows
if(condition)
{
doStuff();
}
else
{
doSomethingElse();
}Your Brace style bears the identifiable stench of a Vagabond Romulan coder, May Fek'lhr forgive your dishonour.

I have been away, but that is not the only difference in C++. For integral types (int, etc…) they can be optimized by the compiler (no function call occurring). When working with class objects it requires a copy of the original to be made, then an increment of the original, and then a return of a temporary object (another copy). That can be a lot of processing for a simple increment and therefore using ‘i++’ instead of ‘++i’ is a bad habit that should be avoided. Note: A non-optimizing C compiler would go through the same steps, but the temporary and return value where usually in the same register, and therefore copying was minimal. P.S. Look it up in puzzle books and other books on optimizing. Or just write a class that requires memory allocation and supports the ‘++’ operator in both pre and post forms and you will see the possible problems.

I didnt know that it did that with class objects thanx very usefull

I prefer the former, but VS 2005 forces me to use the latter. Everyone in my company uses VS 2005 so I have to use the same style to be consistent. Jim
VS2005 doesn't force you. That can be changed in options. However, house style is of course a different matter :)
The only thing unpredictable about me is just how predictable I'm going to be.
