Graphical Interchange Format file (GIF):

It is a type of raster graphics format, where the information about an image is stored in pixel-by-pixel basis.

GIF has a predefined set of colors.

It has 256 unique colors or 8-bit palette, which is nothing but indexed color format.

The images with few colors are best for GIF format.

These images are mostly used in web pages for quick loading of websites.

The information about the colors used in an image is stored in 256 color palettes. It is stored as an array of elements.

It is lossless compression technique; the compression will not affect the quality of the image.

It is suitable for simple diagrams, shapes, and logos since predefined colors are used.

GIF supports animation also and the extension of GIF is “.gif”.

Bitmap Image file (BMP):

It is Microsoft windows OS inbuilt file format for handling graphics files.

This file format stores two-dimensional digital images both monochrome and color, in various color depths.

Bitmap is straight forward image compression technique, which does not compress the image at all.

Joint Photographic Experts Group (JPEG):

It is lossy compression technique; the compression affects the visible quality of the image up to certain limit, and it reduces the size of the image...

In this assignment, you will implement a multi-threaded program (using C/C++) that will check for Prime Numbers and Palindrome Numbers in a range of numbers. Palindrome numbers are numbers that their decimal representation can be read from left to right and from right to left (e.g. 12321, 5995, 1234321). The program will create T worker threads to check for prime and palindrome numbers in the given range (T will be passed to the program with the Linux command line). Each of the threads works on a part of the numbers within the range. Your program should have some global shared variables: • numOfPrimes: which will track the total number of prime numbers found by all threads. numOfPalindroms: which will track the total number of palindrome numbers found by all threads. numOfPalindromic Primes: which will count the numbers that are BOTH prime and palindrome found by all threads. TotalNums: which will count all the processed numbers in the range. In addition, you need to have arrays…
