Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sort…

Chapter 7, Problem 20PP

The Social Security Administration maintains an actuarial life table that contains the probability that a person in the United States will die (http:// www.ssa.gov/OACT/STATS/table4c6.html). The death probabilities from this table for 2009 are stored in the file LifeDeathProbability.txt and it is included on the website for the book. There are three values for each row, the age, death probability for a male, and death probability for a female. For example, the first five lines are:

0 0.006990 0.005728

1 0.000447 0.000373

2 0.000301 0.000241

3 0.000233 0.000186

4 0.000177 0.000150

This says that a 3 year old female has a 0.000186 chance of dying. Write a program that reads the data into arrays from the file. Next, let the user enter his or her sex and age. The program should simulate to what age the user will live by starting with the death probability for the user’s current age and sex. Generate a random number between 0-1; if this number is less than or equal to the death probability then predict that the user will live to the current age. If the random number is greater than the death probability then increase the age by one and repeat the calculation with a new random number for the next probability value.

If the simulation reaches age 120 then stop and predict that the user will live to 120. This program is merely a simulation and will give different results each time it is run, assuming you change the seed for the random number generator.

The following is code for a disc golf program written in C++: // player.h #ifndef PLAYER_H #define PLAYER_H #include <string> #include <iostream> class Player { private: std::string courses[20]; // Array of course names int scores[20]; // Array of scores int gameCount; // Number of games played public: Player(); // Constructor void CheckGame(int playerId, const std::string& courseName, int gameScore); void ReportPlayer(int playerId) const; }; #endif // PLAYER_H // player.cpp #include "player.h" #include <iomanip> Player::Player() : gameCount(0) {} void Player::CheckGame(int playerId, const std::string& courseName, int gameScore) { for (int i = 0; i < gameCount; ++i) { if (courses[i] == courseName) { // If course has been played, then check for minimum score if (gameScore < scores[i]) { scores[i] = gameScore; // Update to new minimum…

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…
