class line
{
public:
line(int Width)
: width(Width)
{
}
private:
int width;
};
I could name Width something like wantedWidth, but I'm just wondering, is there a convention for this or a better way? I don't want to use Hungarian notation.
Yes there's a convention, hundreds of them. Mine is to simply postfix my member names with an underscore.
There is only one convention.. That is to follow it consistently..
There is no convention. Having arguments with the same name as a member "shadows" the member:
class Foo {
int mint;
void hi(int mint) {
mint = 2; // refers to the parameter
}
};
I usually just put a _ before the parameter names to prevent clashing. E.g.
void Myclass::memberFunction (int _param1, int _param2)
{
param1 = _param1;
member = _param2-3;
}
Make up your own convention if you want.
this->width = width (or in your case Width)
A common approach is to use "m" to differentiate member variables. This is most commonly used as a prefix, either mWidth or m_width. But another style (used by ASL, the Adobe Source Libraries) conforms more to the standard C++ names such as size_t by using the "m" as a suffix: width_m.
class line
{
public:
line(int width)
: width_m(width)
{
}
private:
int width_m;
};
I would write this code like this:
class Line
{
public:
Line( int nWidth )
: m_nWidth( nWidth )
{
}
private:
int m_nwidth;
};
In my code - m_* stands for member, n* stands for number (if unsigned number - un and so on ..), all classes are named with capital letters, public is always on the top.
I mean, I prefer the Hungarian notation, it's very clean and useful. You could read this article for more information http://en.wikipedia.org/wiki/Hungarian_notation.
