Students have asked these similar questions
int func(int a, int b)
{
return (a
Static Variable: a variable whose lifetime is the lifetime of the program (static int x;)
Dynamic Variable: It is a pointer to a variable (int *x;)
Is this comparison true?
Using the starter code below, write a program that asks a user for two points (x1, y1) and (x2, y2), then computes the
area of the circle for which (x1, y1) is the center and (x2, y2) is on the circle's perimeter. The program should define and
use 3 functions:
distance(x1, y1, x2, y2): computes and returns the distance between two points
• area(r): computes and returns the area of a circle with radius r
• main(): asks user for input, calls the other functions, and prints the answer.
The input and output of the program should look similar to this:
X for center point: 0
Y for center point: 0
X for perimeter point: 1
Y for perimeter point: 1
Area of circle centered at (0.0, 0.0) with radius 1.414213 is 6.283185.
Hint 1: Area of a circle = n?
Hint2: Distance between 2 points = sqrt(x2-X12 + (Y2 - Y1)²)
Starter code:
import math
def distance(x1, y1, x2, y2):
#Add code to compute and return distance between (x1, y1) and (x2, y2)
def area(r):
#Add code to compute and return area of circle…

- Hospital Charges In Python - Write a program that computes and displays the charges for a patient’s hospital stay. First,the program should ask if the patient was admitted as an in-patient or an out-patient. If thepatient was an in-patient the following data should be entered:• The number of days spent in the hospital• The daily rate• Charges for hospital services (lab tests, etc.)• Hospital medication charges.If the patient was an out-patient the following data should be entered:• Charges for hospital services (lab tests, etc.)• Hospital medication charges.Use a single, separate function to validate that no input is less than zero. If it is, it shouldbe re-entered before being returned.Once the required data has been input and validated, the program should use twoseparate functions to calculate the total charges. One of the functions should acceptarguments for the in-patient data, while the other function accepts arguments for out-patient data. Both functions should return the total…arrow_forward// FixedDebugFive04// Program prompts user for any number of values// (up to 20)// and averages them// C# Programusing System;public class DebugFive04{public static void Main(){int[] numbers = new int[20];const int QUIT = 999;int x;int num;double average;double total = 0;Console.Write("Please enter a number or " +QUIT + " to quit...");num = Convert.ToInt32(Console.ReadLine());x = 0;while ((x < numbers.Length) && num != QUIT){numbers[x] = num;total += numbers[x];Console.Write("Please enter a number or " +QUIT + " to quit...");num = Convert.ToInt32(Console.ReadLine());x++;}average = total / x;Console.WriteLine("The average is {0}", average);Console.WriteLine("The numbers are:");for (int y = 0; y < x; ++y)Console.Write("{0,6}", numbers[y]);}}arrow_forwardbe recor #include #include minutes #include limit on int func(int, int, int, int); main(){ srand(time(NULL)); int a, b, c, fNum; printf("Choose three different numbers between 0-39:"); scanf ("%d%d%d", &a, &b, &c); fNum = func (a, b, c, 25); printf("\nThe result: %d", fNum); } int func (int ul, int u2, int u3, int iter){ srand (time (NULL)); int n1=0, i=0, count=0; for (;iarrow_forward#include using namespace std; const int y = 1; int main () { int static y = 2; int i = 3, j = 4, m = 5, n = 6; %3D int a = [] (int x, int i = 1) { return x * i; } (y, 3) ; %3D int b = [=] (int x) { return [=] (int b) { return b + j; } (x) % 7; } (a); int c = [=] (int x) mutable ->int { m = 6; return [6] (int j) mutable { y = a * b; return y / j; } (x) -m; } (b) ; cout << a << endl; cout << b << endl; cout << c << endl; cout << m << endl; cout << y < endl; return 0; This program outputs 5 lines.
