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);
Answer:
See attachment for program source file
Explanation:
The source code in the question is not incorrect; just that, it was poorly formatted.
So, what I did it that:
I edited the source code to be in the right formats.numeric_limits needs the <limits> header file to work properly. The <limits> header file was not included in the original source file; so, I added #include<limits> at the beginning of the source fileI corrected the wrongly declared function prototypes.See attachment for the modified program source file
To iterate through (access all the entries of) a two-dimensional arrays you
need for loops. (Enter the number of for loops needed).
Answer: You would need two loops to iterate through both dimensions
Explanation:
matrix = [[1,2,3,4,5],
[6,7,8,9,10],
[11,12,13,14,15]]
for rows in matrix:
for numbers in rows:
print(numbers)
The first loop cycles through all the immediate subjects in it, which are the three lists. The second loop calls the for loop variable and iterates through each individual subject because they are lists. So the first loop iterates through the 1st dimension (the lists) and the seconds loop iterates through the 2nd dimension (the numbers in the lists).
To iterate through (access all the entries of) a two-dimensional arrays you need two for loops.
What is an array?A collection of identically typed items, such as characters, integers, and floating-point numbers, are kept together in an array, a form of data structure.
A key or index that can be used to retrieve or change the value kept in that location identifies each element in the array.
Depending on how many indices or keys are used to identify the elements, arrays can be one-dimensional, two-dimensional, or multi-dimensional.
Two nested for loops are often required to iterate over a two-dimensional array: one to loop through the rows, and the other to loop through the columns.
As a result, two for loops would be required to access every entry in a two-dimensional array.
Thus, the answer is two for loops are required.

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

When parameters are passed between the calling code and the called function, formal and actual parameters are matched by: a.
Answer:
their relative positions in the parameter and argument lists.
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
A parameter can be defined as a value that must be passed into a function, subroutine or procedure when it is called.
Generally, when parameters are passed between a calling code and the called function, formal and actual parameters are usually matched by their relative positions in the parameter and argument lists.
A formal parameter is simply an identifier declared in a method so as to represent the value that is being passed by a caller into the method.
An actual parameter refers to the actual value that is being passed by a caller into the method i.e the variables or values that are passed while a function is being called.

Each code will have three letters followed by one digit. The letters and and the digits , , , and will not be used. So, there are letters and digits that will be used. Assume that the letters can be repeated. How many employee ID codes can be generated
Answer:
82,944 = total possible ID's
Explanation:
In order to find the total number of combinations possible we need to multiply the possible choices of each value in the ID with the possible choices of the other values. Since the ID has 3 letters and 1 digit, and each letter has 24 possible choices while the digit has 6 possible values then we would need to make the following calculation...
24 * 24 * 24 * 6 = total possible ID's
82,944 = total possible ID's

a computer file representing a specific text item
Answer:
A document is a written, drawn, presented, or memorialized representation of thought, often the manifestation of non-fictional, as well as fictional, content. The word originates from the Latin Documentum, which denotes a "teaching" or "lesson": the verb doceō denotes "to teach" In general, a document (noun) is a record or the capturing of some event or thing so that the information will not be lost. A document is a form of information. A document can be put into an electronic form and stored in a computer as one or more files. Often a single document becomes a single file.

Explanation:
Given positive integer n, write a for loop that outputs the even numbers from n down to 0. If n is odd, start with the next lower even number.
if(n % 2 == 0){
for(int i = n; i >= 0; i-=2){
System.out.println(i);
}
}
else{
for(int i = n - 1; i >= 0; i-=2){
System.out.println(i);
}
}
Sample output
Output when n = 12

4
2
0
Explanation:The above code is written in Java.
The if block checks if n is even by finding the modulus/remainder of n with 2. If the remainder is 0, then n is even. If n is even, then the for loop starts at i = n. At each cycle of the loop, the value of i is reduced by 2 and the value is outputted to the console.
If n is odd, then the else block is executed. In this case, the for loop starts at i = n - 1 which is the next lower even number. At each cycle of the loop, the value of i is reduced by 2 and the value is outputted to the console.
Sample outputs for given values of n have been provided above.

How to use the RANK Function in Microsoft Excel
Answer:
=RANK (number, ref, [order])
See Explanation
Explanation:
Literally, the rank function is used to rank values (i.e. cells) in a particular order (either ascending or descending).
Take the following instances:
A column used for total sales can use rank function to rank its cells from top sales to least.
A cell used for time can also use the rank function to rank its cells from the fastest time to slowest.
The syntax of the rank function is:
=RANK (number, ref, [order])
Which means:
[tex]number \to[/tex] The rank number
[tex]ref \to[/tex] The range of cells to rank
[tex]order \to[/tex] The order of ranking i.e. ascending or descending. This is optional.
