T009
Comma should not be preceded by whitespace, but should be followed by one
Description:
A comma, whether used as operator or in various lists, should not be preceded by whitespace on its left side, but should be followed by whitespace on its right side:
void fun(int x, int y, int z);
int a[] = {5, 6, 7};
class A : public B,
public C
{
// ...
};
An exception to this rule is allowed for operator,
:
struct A {};
void operator,(const A &left, const A &right);
