Building C++ Values of Shades Program

The aim is to create a program that allows you to enter a matrix of values representing 4 shades of color (white, light gray, dark gray and black) and which displays the corresponding image and then that displays the image with a contrast enhancement. Here's precisely what the program should do: •"entering a matrix NxN mapping (we determine in constant N to 10) with only integer values between 0 and 3; • Display of the corresponding image (display of square feet of shades (white, light gray, dark gray, black) ; • Calculation of the brightness of the image (average of the values contained in the matrix); "change the contents of the matrix by accentuating the contrasts; • Display of the new image.
