السلام عليكم ورحمة الله وبركاته


عندي هوم وورك في البرمجة 202 والتسليم يوم السبت ان شاء الله

بس للاسف ماعرفت كيف يتحل

// الغلط منها محاضرتها كلها كلام فاضي لا يمد للهوم وورك باي صلة :@

ممكن اللي يعررف يفيدني بطريقة وخطوات الحل واكون له من الشاكرين


Problem 2:

The Harris-Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal bolic rate or BMR.

The calories needed for a woman to maintain her weight is:
BMR = 655 + (4.3 * weight in pounds) + (4.7 * height in inches) - (4.7 * age in years)

The calories needed for a man to maintain his weight is:
BMR = 66 + (6.3 * weight in pounds) + (12.9 * height in inches) - (6.8 * age in years)

A typical chocolate bar will contain around 230 calories. Write a program that allows the user to input their weight in pounds, height in inches, and age in years. The program should then output the number of chocolate bars that should be consumed to maintain one’s weight for both a woman and a man of the input weight, height, and age.

Notes:

This project gives the student practice with numerical calculations and simple input/output. For a slightly more challenging problem allow the height to be entered in feet and inches and have the program convert to inches.

1 kg = 2.2046226218487757 pounds
1 m = 39.37007874015748 inches






















Problem 3:

Many private water wells produce only 1 or 2 gallons of water per minute. One way to avoid running out of water with these low-yield wells is to use a holding tank. A family of 4 will use about 250 gallons of water per day. However, there is a “natural” water holding tank in the casing (i.e. the hole) of the well itself. The deeper the well, the more water that will be stored that can be pumped out for household use. But how much water will be available?

Write a program that allows the user to input the radius of the well casing in inches (a typical well will have a 3 inch radius) and the depth of the well in feet (assume water will fill this entire depth, although in practice that will not be true since the static water level will generally be 50 feet or more below the ground surface). The program should output the number of gallons stored in the well casing. For your reference:

The volume of a cylinder is where r is the radius and h is the height.
1 cubic foot = 7.48 gallons of water.

For example, a 300 foot well full of water with a radius of 3 inches for the casing holds about 441 gallons of water -- plenty for a family of 4 and no need to install a separate holding tank.

Notes:

This project gives the student practice with numerical calculations and simple input/output. Introduces problem solving with relatively straightforward conversion of units. Students are likely to encounter data type conversion issues from double to int and vice versa (e.g. radius / 12 will result in 0 if radius is an int).

بالنسبه للسؤال الاول يبغاك تحسبين في كم قطعة شوكلاته يقدر ياكلها الشخص بحيث انو يحافظ على وزنه ..
اول شي تطلبي من المستخدم يدخل الطول بـ inches و الوزن بـ pounds و العمر بالسنه
ثاني شي تحسبي الـBMR بحسب المعادله فوق
بعدين تقسمين BMR/230 وتحسبين كم قطعة شوكلاته ياخذ اذا كان رجال او حرمه ,,

أتمنى أكون فهمتك ,,

هذا طبعا ً حل دكتوره غاده معانا زمان

Solution:

Problem Analysis Chart:

Given Data Required Results
weight
height
age
numCaloriesChocolateBar numChocolateBarsForFemale

Processing Required Solution Alternatives
caloriesMale= 655 + (4.3 * weight) + (4.7 * height) - (4.7 * age);
numChocolateBarsForMale = caloriesMale / numCaloriesChocolateBar

caloriesFemale = 66 + (6.3 * weight) + (12.9 * height) - (6.8 * age);
numChocolateBarsForWoman = caloriesFemale / numCaloriesChocolateBar
caloriesMale = 655 + (4.3 * weight) + (4.7 * height) - (4.7 * age);

System.out.println("A male with those measurements should eat " +
(caloriesMale / 230) + “candy bars per day to maintain her weight.");


caloriesFemale = 66 + (6.3 * weight) + (12.9 * height) - (6.8 * age);

System.out.println("A female with those measurements should eat " +
(caloriesFemale / 230) + “candy bars per day to maintain her weight.");

Algorithm:

1. Read Weight from user.
2. Read Height from user.
3. Read Age from user.
4. Calculate number of calories a male person can consume without gaining weight.
5. Calculate number of chocolate bars a male person can consumer without gaining weight.
6. Calculate number of calories a female person can consume without gaining weight.
7. Calculate number of chocolate bars a female person can consumer without gaining weight.
8. Displaynumber of calories a male person can consume without gaining weight.
9. Display number of calories a female person can consume without gaining weight.






Sample Code Solution:

import java.util.Scanner;

public class CandyCalculator
{
public static void main(String[] args)
{
Scanner keyboard = new Scanner(System.in);
int age;
int weight;
int height;

System.out.println("This program will calculate the number of 230 calorie");
System.out.println("candy bars to eat to maintain your weight.");
System.out.println("What is your age in years?");
age = keyboard.nextInt();
System.out.println("What is your total height in inches?");
height = keyboard.nextInt();
System.out.println("What is your weight in pounds?");
weight = keyboard.nextInt();

double caloriesMale, caloriesFemale;

caloriesMale = 655 + (4.3 * weight) + (4.7 * height) - (4.7 * age);
caloriesFemale = 66 + (6.3 * weight) + (12.9 * height) - (6.8 * age);

System.out.println("A female with those measurements should eat " +
(caloriesFemale / 230) +
" candy bars per day to maintain her weight.");
System.out.println("A male with those measurements should eat " +
(caloriesMale / 230) +
" candy bars per day to maintain her weight.");
}

السؤال الثاني بأحط لك الحل وانتِ فهميه نفسك هو سهل و واضح بس تشوفي الحل بتفهميه ان شاءالله

Solution:

Problem Analysis Chart:

Given Data Required Results
radiusInInches
depthInFeet
CUBIC_FEET_PER_GALLON = 7.48
PI = 3.14159 gallons
Processing Required Solution Alternatives
radiusInFeet = radiusInInches / 12
volumeOfWell =
galons = volumeOfWell * CUBIC_FEET_PER_GALLON = 7.48
gallons = (int) ((Math.PI * (radius / 12.0) * (radius / 12.0) * depth) * CUBIC_FEET_PER_GALLON);


Algorithm:

1. Readradius from user.
2. Read depth from user.
3. Read Age from user.
4. Convert entered radius from inches to feet.
5. Calculate volume of well.
6. Calculate number of gallons in well.
7. Display number of gallons in well.









Sample Code Solution:

Solution:

import java.util.Scanner;

public class WaterWell
{
public static final double CUBIC_FEET_PER_GALLON = 7.48;

public static void main(String[] args)
{
Scanner keyboard = new Scanner(System.in);
int radius;
int depth;
int gallons; // This could be a double, it's not specified in the problem

System.out.println("This program calculates how much water will be available in a well.");
System.out.println("What is the radius of the casing in inches?");
radius = keyboard.nextInt();
System.out.println("What is the depth of the well in feet?");
depth = keyboard.nextInt();

// Compute gallons, first converting the radius to feet, then computing the volume
// and multiplying by the conversion factor of cubic feet to gallons
gallons = (int) ((Math.PI * (radius / 12.0) * (radius / 12.0) * depth) * CUBIC_FEET_PER_GALLON);

System.out.println("The well contains " + gallons + " gallons.");
}
}
