Concept explainers
Write a program that computes the annual after-tax cost of a new house for the first year of ownership. The cost is computed as the annual mortgage cost minus the tax savings. The input should be the price of the house and the down payment. The annual mortgage cost can be estimated as 3 percent of the initial loan balance credited toward paying off the loan principal plus 6 percent of the initial loan balance in interest. The initial loan balance is the price minus the down payment. Assume a 35 percent marginal tax rate and assume that interest payments are tax deductible. So, the tax savings is 35 percent of the interest payment. Your program should use at least two function definitions and should allow the user to repeat this calculation as often as the user wishes.

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
