Read the following code: # Calculate average
average = numl + num2 + num3 / 3.0

There is an error in the code. How should the code be revised in order to get the correct output?

A:average = numl + num2 + num3 - 3.0

B:average = numl + num2 + num3 - 3.0

C: average = (numl + num2 + num3) / 3.0

D: average = numl + num2 + num3 / (3.0)

Pthreads programming: create and terminate a thread write a c++ program that creates a thread. the main will display a message “hello world from the main”. the main will create a thread that will display a message “hello world from the thread” and then terminates with a call to pthread_exit()

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.
