Populations are effected by the birth and death rate, as well as the number of people who move in and out each year. The birth rate is the percentage increase of the population due to births and the death rate is the percentage decrease of the population due to deaths. Write a program that displays the size of a population for any number of years. The program should ask for the following data:
• The starting size of a population
• The annual birth rate
• The annual death rate
• The number of years to display
Write a function that calculates the size of the population for a year. The formula is
N = P + BP − DP
where N is the new population size, P is the previous population size, B is the birth rate, and D is the death rate.
Input Validation: Do not accept numbers less than 2 for the starting size. Do not accept negative numbers for birth rate or death rate. Do not accept numbers less than 1 for the number of years.
#include
using namespace std;
double calcOfPopulation(double, double, double);
double inputValidate(double, int);
int main()
{
double P, // population size
B, // birth rate %
D, // death rate %
num_years;
cout << "Starting size of population: ";
P = inputValidate(P, 2);
cout << "Annual birth rate: %";
B = inputValidate(B, 0);
cout << "Annual death rate: %";
D = inputValidate(D, 0);
cout << "Number of years to display: ";
num_years = inputValidate(num_years, 1);
cout << "Population size for "
<< num_years << " years "
<< " = "
<< (calcOfPopulation(P, B, D) * num_years)
<< endl;
return 0;
} // END int main()
double inputValidate(double number, int limit)
{
while(!(cin >> number) || number < limit)
{
cout << "Error. Number must not be "
<< " 0 or greater:";
cin.clear();
cin.ignore(numeric_limits::max(), '\n');
}
return number;
}
double calcOfPopulation(double P, double B, double D)
{
B *= .01; // 3.33% = .0333
D *= .01; // 4.44% = .0444
return P + (B * P) - (D * P);

In this lab, you use what you have learned about searching an array to find an exact match to complete a partially prewritten C program. The program uses an array that contains valid names for 10 cities in Michigan. You ask the user to enter a city name; your program then searches the array for that city name. If it is not found, the program should print a message that informs the user the city name is not found in the list of valid cities in Michigan. The file provided for this lab includes the input statements and the necessary variable declarations. You need to use a loop to examine all the items in the array and test for a match. You also need to set a flag if there is a match and then test the flag variable to determine if you should print the the Not a city in Michigan. message. Comments in the code tell you where to write your statements. You can use the previous Mail Order program as a guide. Instructions Ensure the provided code file named MichiganCities.cpp is open. Study the prewritten code to make sure you understand it. Write a loop statement that examines the names of cities stored in the array. Write code that tests for a match. Write code that, when appropriate, prints the message Not a city in Michigan.. Execute the program by clicking the Run button at the bottom of the screen. Use the following as input: Chicago Brooklyn Watervliet Acme

Write functions to compute a subset, find member, union, and intersection of sets. Follow the steps below:

1. Read two integers from the user.
2. Suppose one of the integers is 2311062158. The binary equivalent of this integer stored in a register will be 1000 1001 1100 0000 0000 0010 1000 1110. This data should be regarded as bit strings representing subsets of the set {1, 2, … 32}. If the bit string has a 1 in position i, then element i is included in the subset. Therefore, the string: 1000 1001 1100 0000 0000 0010 1000 1110 corresponds to the set: {2, 3, 4, 8, 10, 23, 24, 25, 28, 32}.
3. Print out members of the set from smaller to larger. You can do a loop from 1 to 32. Load a masking bit pattern that corresponded to the position number of the loop counter (0x00000001 for 1). Isolate the bit in the operand by using the AND operation. If the result of the AND is not 0 then the loop counter is in the set and should be displayed. Increment the counter and shift the masking bit pattern to the left.
4. Read a number from the user. Determine if that element is a member of the given sets.
5. Determine the union of two sets.
6. Determine the intersection of two sets.
7. Implement a loop back to the main function. See the prompts below: "Enter the first number:" "Enter the second number:" "Members of Set 1:" "Members of Set 2:" "Enter an element to find:" "It is a member/ not a member of set 1" "It is a member/ not a member of set 2" "Union of the sets:" "Intersection of the sets:" "Do you want to compute set functions again?"
8. Test the program using the following data:

Enter the first number: 99999
Enter the second number: 111445
Members of set 1: 1 2 3 4 5 8 10 11 16 17
Members of set 2: 1 3 5 7 9 10 13 14 16 17
Enter an element to find: 7
It is not a member of set 1
It is a member of set 2
Union of the sets: 1 2 3 4 5 7 8 9 10 11 13 14 16 17
Intersection of the sets: 1 3 5 10 16 17
