3.2.3 Operators
Put spaces between all multi-operand operators so it doesn't look like a bunch of jumbled up math. Don't put spaces for parenthesis.
Accessing an array has no spaces: a[3]
A multi operand operator is such that has a left and right value, such as 2 + 3.
A single operand operator is one that only has a single value, like -2 or ~0x32
In addition to the above section, the following Java-specific operators require spaces: `>>> >>>= instanceof ->
The :: operator in Java 8 does not require a space: Foo::blah
BAD:
System.out.println("hello"+Blah.SPACE+"world");
int a=(1+b/-(s+2));
GOOD:
System.out.println("hello" + Blah.SPACE + "world");
int a = (1 + b / -(s + 2));
Lambdas are weird and they have weird spacing. Just treat every segment as a separate section and apply the relevant style. Here is an example of the proper spacing of a lambda:
(final int foo, final boolean bar) -> int {
return 42;
}
The sizeof, alignof, *_cast, noexcept, and typeid operators follow the same rules of functions.
There are no spaces for the *, &, and -> (pointer accessing) operators
BAD:
std:: cout<<std::string("hello")+Blah.SPACE +"world";
int a=(1+b/-(s+2));
GOOD:
std::cout << std::string("hello") + Blah.SPACE +"world";
int a = (1 + b / -(s + 2));
