Problem 1 - Function Declarations Write the prototypes for several function calls, deducing the correct signature from the context in PrototypeTester. cpp Do not implement the functions themselves. That is already done. Place the prototypes in pe04.h. Problem 2 - Write a Function Write a function named binToDec() that accepts an integer parameter whose digits are meant to represent binary (base-2) digits, and converts that integer's representation to decimal (base-10). The function should return the integer value before it was converted. For example, given this code:

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.
