please answer in C++

Assignment3B: Image Color Depth: In Assignment 1, we learned that each pixel of a computer image is represented with three values, RGB. Traditionally one byte is used for each color, meaning that each pixel takes up 3 bytes of space. These are known as 8 bits per color channel encoding, or 8 BPC for short. More recently, encodings with larger ranges of color have become popular with artists and photographers. Programs like Photoshop now support 16 BPC and 32 BPC encoding. For this assignment, you will try to determine the encoding of an RGB image based on its width, height, and file size. After the user enters this information, you will first check if the information is valid. If not, you will notify the user and skip to the end of the program. (Hint: You will have to check multiple potential issues with your IF statements) If the detail is valid, you will then calculate the BPC encoding. Based on the value, you will use a Switch statement to print out if the image is 8,16 , or 32 BPC. If it is outside the range, inform the user that your computer does not know how to read this encoding. You must call the class Assignment3B and put it in a file called "Assignment3B.java", "Assignment3B.cs", or "Assignment3B.cpp". Make sure to use Switch statements to complete this assignment - you will lose points if you do not. Sample Output \#1: [Image Encoding Checker] What is the image width? 10 What is the image height? -20 What is the file size (in bytes)? -200 The information is invalid - please re-enter it. Sample Output \#2: [Image Encoding Checker] What is the image width? 10 What is the image height? 20 What is the file size (in bytes)? 202 The information is invalid - please re-enter it. Sample Output \#3: [Image Encoding Checker] What is the image width? 50 What is the image height? 50 What is the file size (in bytes)? 7500 The RGB image is encoded with 8 bits per channel. Sample Output \#4: [Image Encoding Checker] What is the image width? 100 What is the image height? 100 What is the file size (in bytes)? 60000 The RGB image is encoded with 16 bits per channel
