Which of these 2 programming styles do you prefer? Why? Are there particular advantages to one over the other?
// Style 1
if (doBorder)
doTheBorder();
if (doFrame)
doTheFrame();
if (doDraw)
doTheDraw();
void doTheBorder()
{
// ...
}
void doTheFrame()
{
// ...
}
void doTheDraw()
{
// ...
}
// Style 2
doTheBorder();
doTheFrame();
doTheDraw();
void doTheBorder()
{
if (!doBorder)
return;
// ...
}
void doTheFrame()
{
if (!doFrame)
return;
// ...
}
void doTheDraw()
{
if (!doDraw)
return;
// ...
}
