What kind of monsters don't use parentheses on sizeof. Is it the same guys that put { on new lines and have giant comment templates for every one line function.
But work long enough in either one of those styles, and the other one will start to look strange.
Indentation is how you should identify blocks.
switch( c ) {
case 'A':
simple_stuff();
break;
case 'B': {
int temporary_variable = 0;
complex_stuff( temporary_variable );
}
It's all backward. The IDE should SHOW you the blocks somehow (background tone changes etc), and let you edit the blocking explicitely. If they look wrong, you select and hit a key. Now you're in agreement with the compiler.
I don't know what the point is in pretending IDEs or advanced text editors don't exist.
There is here.
In some dialects, you can only declare a variable at the start of a block. From the perspective of the compiler, a "case block" isn't actually a block, just stuff between labels. In order to declare temporary_variable, it may be necessary to put the braces, and it is probably best practice as temporary_variable may otherwise be exposed to later cases (and in C++, a jump over a variable declaration seems to produce an error).
To me its more about conserving an extra bit of vertical space... I like my methods/functions quite compact. In the past I liked the balanced nature of the braces though.
Makes absolutely no appreciable difference though of course, as long as you don't get into a formatting war with your team.
