I am writing some Win32 program. and I meet a problem. I define an array of Point,just like this:
POINT points[3];
and now I want to Initialize it, and I know this is illegal
POINT points[3] = { (295,295),(200,200),(400,500) };
so I need the correct way.
You can do it simply as
POINT points[3] = { 295, 295, 200, 200, 400, 500 };
but a safer thing to do would be this
POINT points[3] = { { 295, 295 }, { 200, 200 }, { 400, 500 } };
The amusing part is that what you originally wrote is not illegal (where did you get that idea?). The () you used inside your initializer will cause the inner , to be interpreted as comma operator. For example, expression (400, 500) evaluates to 500. That means that your original initializer is actually treated as
POINT points[3] = { 295, 200, 500 };
which is in turn equivalent to
POINT points[3] = { { 295, 200 }, { 500, 0 }, { 0, 0 } };
It doesn't do what you want it to do, but it is certainly not illegal.
As per the comments:
POINT points[] = {{295,295}, {200,200}, {400,500}};
