Cycle through struct elements [duplicate]

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

@JVApen I don't need all variables (well, colors) of that type to be "transparent-white"! :) — Jimmy Scionti

@Someprogrammerdude thanks. Apologies... I'm a beginner and don't even have a book to follow. :\ I should. — Jimmy Scionti

Struct and class are the same thing, just different behavior regarding default access — JVApen

Just use something like

Color color;
color = { 0 };
