Population
In a population, the birth rate and death rate are calculated as follows:
Birth Rate = Number of Births ÷ Population
Death Rate = Number of Deaths ÷ Population
For example, in a population of 100,000 that has 8,000 births and 6,000 deaths per year, the birth rate and death rate are:
Birth Rate = 8,000 ÷ 100,000 = 0.08
Death Rate = 6,000 4 ÷ 100,000 = 0.06
Design a Population class that stores a population, number of births, and number of deaths for a period of time. Member functions should return the birth rate and death rate. Implement the class in a
Input Validation: Do not accept population figures less than 1, or birth or death numbers less than 0.

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…arrow_forward
