Assume that a box of apples cost 8 dollars and a box of grapes cost 6 dollars. Given variables numBoxApples and numBoxGrapes that are read from input, compute the total cost and assign combinedCost with the result. Ex: If the input is 7 10, then the output is: Cost: 116 include <iostream> using namespace std; int main() { int applePrice = 8; int grapePrice = 6; int numBoxApples; int numBoxGrapes; int combinedCost; cin >> numBoxApples; cin >> numBoxGrapes; /* Your code goes here */ cout << "Cost: " << combinedCost << endl; return 0; }
Determine the distance between point (x1, y1) and point (x2, y2), and assign the result to pointsDistance. The calculation is:Distance = SquareRootOf( (x2 - x1)2 + (y2 - y1)2 ) #include <stdio.h>#include <math.h> int main(void) { double x1; double y1; double x2; double y2; double xDist; double yDist; double pointsDistance; xDist = 0.0; yDist = 0.0; pointsDistance = 0.0; scanf("%lf", &x1); scanf("%lf", &y1); scanf("%lf", &x2); scanf("%lf", &y2); /* Your solution goes here */ printf("%lf\n", pointsDistance); return 0;
Write a program that prints a grocery receipt of items purchased. The program must create variables for the following items: Milk = $2.00 Eggs = $ 3.00 Bread =$4.00 Orange Juice =$3.50 Apples = $4.00 Cookies = $3.25 Water = $3.00 A coupon of $1.00 was used. use a constant for a coupon. Calculate the bill, assume that 1 unit of all items was purchased use java programming language
Question: (Code must be in java language) Assuming that you have the functions “drawPolygon(int[] x, int[] y, int n)” for drawing polygon, “drawRectangle(int x, int y, int width, int height)” for drawing rectangle and “drawCircle(int xc, intyc, int radius)” for drawing circle; draw the given shape. Where: R(300,250), T1(325,275), T2(475,275), T3(400,400), P1(285,250), P2(225,275), P3(200,450), P4(285, 300), Q1(515,250), Q2(575,275), Q3(600,450), Q4(515,300)//Look attached image here Note: No need to write the definition of the methods, there are no marks for definition. Only use method calls to create the shape as shown in Figure 1.
An emirp (prime spelled backward) is a nonpalindromic prime number whose reversal is also a prime. For example, both 17 and 71 are prime numbers, so 17 and 71 are emirps. Write a program that displays the first 100 emirps. Display 10 numbers per line, as follows: please complete this problem by defining three functions: (1) def reverse(number) example: input: 13 output:31 (2) def isPrime(number) example: input: 13 output:True; input: 14 output:False (3) def main() define a main function to display 100 numbers which is emirp, 10 numbers per line
Write a program for calculating the simple interest on a loan when the initial prin- cipal amount (princi_amnt) is $1000, the initial interest rate (int_rate) is 5.0%, and the number of years (no_of_yrs) is 5. Use suitable data types to declare these variables. Simple interest is calculated using the following equation: Simple interest = (Principal amount * Interest rate * Number of years)/100
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('%0.2f' % your_value) Ex: If the input is: 20.0 3.1599 the output is: 1.58 7.90 63.20 Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with: 50 20.0 3.1599 the function returns: 7.89975 def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon) Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles. Note: This is a lab from a previous chapter that now requires the use of a function.
Driving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles. Output each floating-point value with two digits after the decimal point, which can be achieved by executingcout << fixed << setprecision(2); once before all other cout statements. Ex: If the input is: 20.0 3.1599 the output is: 3.16 11.85 79.00 Note: Real per-mile cost would also include maintenance and depreciation.
