Answer: $1,500

Explanation:

The future value of value using simple interest is:

Future value = Value * ( 1 + rate * time)

2,400 = Value * (1 + 15% * 4)

2,400 = Value * 1.6

Value = 2,400 / 1.6

Value = $1,500

Describe a strategy for avoiding nested conditionals. Give your own example of a nested conditional that can be modified to beco

harina [27]

Answer:

One of the strategies to avoid nested conditional is to use logical expressions such as the use of AND & operator.

One strategy is to use an interface class with a method. That method can be created to be used for a common functionality or purpose. This is also called strategy design pattern. You can move the chunk of conditional statement to that method. Then each class can implement that interface class and use that shared method according to their own required task by creating objects of sub classes and call that common method for any such object. This is called polymorphism.

Explanation:

Nested conditionals refers to the use of if or else if statement inside another if or else if statement or you can simply say a condition inside another condition. For example:

if( condition1) {

//executes when condition1 evaluates to true

if(condition2) {

//executes when condition1 and condition2 evaluate to true

} else if(condition3) {

//when condition1 is true and condition3 is true

} else {

//condition1 is true but neither condition2 nor conditions3 are true

} }

The deeply nested conditionals make the program difficult to understand or read if the nested conditionals are not indented properly. Also the debugging gets difficult when the program has a lot of nested conditionals.

So in order to avoid nested conditionals some strategies are used such as using a switch statement.

Here i will give an example of one of the strategies i have mentioned in the answer.

Using Logical Expressions:

A strategy to avoid nested conditionals is to use logical expressions with logical operators such as AND operator. The above described example of nested conditionals can be written as:

if(condition1 && condition2){ //this executes only when both condition1 and condition2 are true

} else if(condition1 && condition3) {

this executes only when both condition1 and condition3 are true

} else if(condition1 ){

//condition1 is true but neither condtion2 nor condtion3 are true }

This can further be modified to one conditional as:

if(!condition3){

// when condition1 and condition2 are true

}

else

// condition3 is true

Now lets take a simple example of deciding to go to school or not based on some conditions.

if (temperature< 40){

if (busArrived=="yes") {

if (!sick) {

if (homework=="done") {

printf("Go to school.");

}

This uses nested conditionals. This can be changed to a single conditional using AND logical operator.

if ((temperature <40) && (busArrived=="yes") &&

(!sick) && (homework=="done"))

{ cout<<"Go to school."; }

What output is produced by

Natasha_Volkova [10]

Answer:

The answer to this question is given below in the explanation section. the correct option is C.

Explanation:

This is Java code statement:

System.out.print("Computing\nisInfun");

The output of this code statement is

Computing

isInfun

However, it is noted that the C option is not written correctly, but it is guessed that it will match to option C.

This Java code statement first prints "Computing" and then on the next line it will print "isInfun" because after the word "Computing" there is a line terminator i.e. \n. when \n will appear, the compiler prints the remaining text in the statement on the next line.

Write an inheritance hierarchy for classes Quadrilateral, Trapezoid, Parallelogram, Rectangle and Square. Use Quadrilateral as t

Ymorist [56]

Answer:

CODE:

public class QuadrilateralTest {

public static void main(String[] args) {

// NOTE: All coordinates are assumed to form the proper shapes

// A quadrilateral is a four-sided polygon

Quadrilateral quadrilateral =

new Quadrilateral(1.1, 1.2, 6.6, 2.8, 6.2, 9.9, 2.2, 7.4);

// A parallelogram is a quadrilateral with opposite sides parallel

Parallelogram parallelogram =

new Parallelogram(5.0, 5.0, 11.0, 5.0, 12.0, 20.0, 6.0, 20.0);

// A rectangle is an equiangular parallelogram

Rectangle rectangle =

new Rectangle(17.0, 14.0, 30.0, 14.0, 30.0, 28.0, 17.0, 28.0);

// A square is an equiangular and equilateral parallelogram

Square square =

new Square(4.0, 0.0, 8.0, 0.0, 8.0, 4.0, 4.0, 4.0);

System.out.printf(

"%s %s %s %s\n", quadrilateral, parallelogram,

rectangle, square);

}

RESULT:

Coordinates of Quadrilateral are:

2 (1.1, 1.2), (6.6, 2.8), (6.2, 9.9), (2.2, 7.4)

4 Coordinates of Parallelogram are:

5 (5.0, 5.0), (11.0, 5.0), (12.0, 20.0), (6.0, 20.0)

6 Width is: 6.0

7 Height is: 15.0

8 Area is: 90.0

10 Coordinates of Rectangle are:

11 (17.0, 14.0), (30.0, 14.0), (30.0, 28.0), (17.0, 28.0)

12 Width is: 13.0

13 Height is: 14.0

14 Area is: 182.0

16 Coordinates of Square are:

17 (4.0, 0.0), (8.0, 0.0), (8.0, 4.0), (4.0, 4.0)

18 Side is: 4.0

19 Area is: 16.0
