1.. A digital world colors are specified in Red ,Green ,Blue(RGB) format with value of (R,G,B) varying on integers scale from 0 to 255 in point publishing the colors are mentioned in cyan, magenta - yellow black (CMYK) format ,with value of C,M,Y and k varying on real scale from 0.0 to 1.0 write the program to convert RGB colors to CMYK as per the following formula.. White=max(Red/255,Green/255,Blue/255), cyan=(white-Red/255)/white Magenta=(white -Green/255)/white black = 1-white. note that if RGB value are all 0 then the cmy values are all 0 and the k value is 1.
