Yes, but an operator is more visible than a missing brace :-)

Forcing parenthesis everywhere can make code more difficult to read sometimes, as in:

if ((a == 3) || (b == 5) || (c == 4))
vs
if (a == 3 || b == 5 || c == 4)

So I also favor the "best legibility" rule. Let's restate it as something like "the minimum number of parenthesis that
clearly isolate a conditional logic block. Example:

Right: if (a == 3 || (b == 5 && d != 20) || c == 4)
Wrong: if (a == 3 || b == 5 && d != 20 || c == 4)

If we use this style, for consistency I think the constructor of a derived class should be:

MyClass::MyClass(int i, char c, int *p) :
  TQObject(),
  m_i(i),
  m_c(c),
  m_p(p),
  m_d(d)
{
  do_something();
}

since the "base block" is just another part of the class object, as any other member.
My only concern is that with big classes, the list of members can be quite long and so requires some scrolling from
the constructor definition line to the actual constructor body. I usually use this style:

MyClass::MyClass(int i, char c, int *p) :
  m_i(i), m_c(c), m_p(p),
  m_d(d)
{
  do_something();
}

which is somehow more compact, but I am fine with both versions.

Done. Also added a question about variable/function/class names.
