Cycle through struct elements

Question

I defined the following struct:

struct Color {
    unsigned int r, g, b, a;
};

Is there a way to cycle through its elements like:

Color c;

for (unsigned int i "in all struct elements") {
    c.i = 0;
}

So that, after that, all 4 unsigned int in c are set to 0?

Initialize at definition like `Color c = {};`? "Reset" using assignment as `c = {};`? Plain old setting bytes of memory as `std::memset(&c, 0, sizeof c);`? — Some programmer dude, Mar 04 '20 at 12:01
@JVApen I don't need all variables (well, colors) of that type to be "transparent-white"! :) — Jimmy Scionti, Mar 04 '20 at 12:06
@Someprogrammerdude thanks. Apologies... I'm a beginner and don't even have a book to follow. :\ I should. — Jimmy Scionti, Mar 04 '20 at 12:06
@JVApen, you mean a class then? Maybe. Right now that simple struct in the example works fine. I might change it to a class later. — Jimmy Scionti, Mar 04 '20 at 15:56
Struct and class are the same thing, just different behavior regarding default access — JVApen, Mar 04 '20 at 16:10

Just use something like

Color color;
color = { 0 };
