We write a program for this problem using C++.
What is Programming language?
A programming language is a vocabulary and grammar system used to give instructions to a computer or other computing equipment so that it can carry out particular activities. • High-level languages like BASIC, C, C++, COBOL, Java, FORTRAN, Ada, and Pascal are referred to as programming languages.
Code for the given problem:
#include <iostream>
#include <string>
#include <iomanip>
using namespace std;
void get_input(double& principle, double& interest, double& payment);
/* This function asks the user to input the principle, interest,
and payment amount, and only accepts positive numbers for input.
All three parameters are call-by-reference, so the function
in effect returns the three values by changing the values of
the arguments which are passed to it. The initial values of
these parameters are ignored and overwritten.
*/
double pay_off_loan(double principle, double rate, double payment,
int& months, double& total_interest);
/* This function assumes the payment is enough
to cover first month's interest. It has a loop to
pay off the loan one month at a time.
Pre-Condition:
principle = starting principle.
rate = monthly interest rate expressed as a decimal.
payment = amount of monthly payment, which must be high
enough to pay off the first month's interest.
Post-Condition:
amount of final payment is returned by the function.
months = number of months it took to pay off loan.
total_interest = total amount of interest paid during
that time.
It may help to think of principle, rate, and payment as
input parameters, and months, and total_interest
as output parameters.

int main()
{
double principle, interest, payment, monthly_rate;
double final_payment, total_interest, monthly_interest;
int months;
get_input(principle, interest, payment);
monthly_rate = interest/12/100;

cout << endl;

cin >> interest;
}
cout << "What is the monthly payment amount? $";
cin >> payment;
while(payment <= 0)
{
cout << "You must enter a positive number!" << endl;
cout << "What is the monthly payment amount? $";
cin >> payment;
}
}
double pay_off_loan(double principle, double rate, double payment,
int& months, double& total_interest)
{
double final_payment = 0;
double monthly_interest;
months = 0;
total_interest = 0;
while(principle > 0)
{
monthly_interest = principle * rate;
total_interest += monthly_interest;
principle = principle + monthly_interest - payment;
months++;
}
if(principle < 0)
final_payment = principle + payment;
else
final_payment = payment;
return final_payment;
}
Output:
How much do you want to borrow? $15000
What is the annual interest rate expressed as a percent? 11
What is the monthly payment amount? $2500
Your debt will be paid off after 7 months, with a final payment of just $ 500.71
The total amount of interest you will pay during that time is $500.71

What is a while loop? How does it work?
A while loop is a control flow statement that enables code to be performed repeatedly in most computer programming languages based on a specified Boolean condition. You can think of the while loop as an iterative if statement.
The while loop runs the code after first determining if the condition is true. Until the given condition returns false, the loop doesn't end. As an alternative, the do while loop only executes its code a second time if the condition is satisfied after the first execution.

which cloud computing service model describes cloud-based systems that are delivered as a virtual solution for computing that allows firms to contract for utility computing as needed rather than build data centers?
Infrastructure as a Service is the concept that is cloud-based systems that is supplied as virtualized solution for computing that permits businesses to pay for utility computing instead of building data centers.
Describe data.
Data are a group of discrete values that describe amount, quality, fact, statistics, or other fundamental units of meaning, or they can simply be a series of symbols that can be further understood. A data is a specific value included in a group of data. The majority of the time, data is arranged into smaller structures, such tables, which give more context and meaning and can also be used as information in larger structures. It's possible to use data as variables in a calculation. Data can represent intangible concepts.

whose name is attached to a type of computer architecture characterized by storing a program in the same place as regular data?
"Von Neumann" is the name attached to a type of computer architecture characterized by storing a program in the same place as regular data.
Explain Computer Architecture.
Computer architecture is a body of guidelines and techniques used in computer engineering to describe the operation, structure, and application of computer systems. The structure of a system is described in terms of its components, each of which is separately identified, and how they relate to one another.
Von Neumann architecture, still utilized by the majority of computer types today, is a very good example of computer architecture. The mathematician John von Neumann made this suggestion in 1945. It describes how the CPU of an electronic computer, which consists of an arithmetic logic unit, a control unit, registers, memory for data and instructions, an input/output interface, and external storage capabilities, is built.
