operator<< for a Color

A struct Rgb with three public ints r, g, b is given. Complete the free function ostream& operator<<(ostream& os, const Rgb& c) so that a color prints as rgb(, the three values separated by a comma and a space, then ). Do not print a newline; return os.

Output of Rgb red{255, 0, 0}; cout << red << "\n"; (see Expected Output).

Do NOT write a main function.

Expected Output:

rgb(255, 0, 0)↵
[rgb(10, 20, 30)]↵

= newline. The output ends with a newline — print one after the last line.
