The pointer to the dynamic array is called data, and the size of the dynamic array is stored in a private member variable called capacity. Write the following new member function: (C++ LANGUAGE) void bag::triple_capacity( )
// Postcondition: The capacity of the bag's dynamic array has been
// tripled. The bag still contains the same items that it previously
// had.

Do not use the reserve function, do not use realloc, and do not cause a heap leak. Do make sure that both data and capacity have new values that correctly indicate the new larger array.

Me with this program in c++ ! computers represent color by combining sub-colors red, green, and blue (rgb). each sub-color's value can range from 0 to 255. thus (255, 0, 0) is bright red. (130, 0, 130) is a medium purple. (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (in other word, equal amounts of red, green, blue yield gray).given values for red, green, and blue, remove the gray part. ex: if the input is 130 50 130, the output is: 80 0 80. thus, find the smallest value, and then subtract it from all three values, thus removing the gray.
