What is the purpose of the " + " in the code labeled // line 2 below ?

int sum;
int num1 = 3;
int num2 = 2;
sum = num1 + num2; // line 1
System.out.println(num1 + " + " + num2 + " = " + sum);// line 2

Answers

Answer 1

Answer:

To illustrate addition operation

Explanation:

Given

The above code segment

Required

Determine the purpose of "+" in label line 2

In line 2, num1 = 3  and num2 = 2 in line 3.

sum = 2 + 3 = 5 in line 4

From the given code segment, the plus sign is used as a string literal (i.e. "+").

This means that, the print statement will output: 3 + 2 = 5

The "+" is printed in between 3 and 2.

So, the purpose of the "+" is to show the function of the program and the function of the program is to illustrate an addition operation between two variables

Preference shareholders can convert their shares to Equity shares but equity shareholders do not have the same courtesy.Preference shares can only be sold back to the company while equity shares can be sold to anybody.

The Westfield Carpet Company has asked you to write an application that calculates the price of carpeting for rectangular rooms. To calculate the price, you multiply the area of the floor (width times length) by the price per square foot of carpet. For example, the area of floor that is 12 feet long and 10 feet wide is 120 square feet. To cover that floor with carpet that costs $8 per square foot would cost $960. (12 × 10 × 8 = 960.) First, you should create a class named RoomDimension that has two FeetInches objects as attributes: one for the length of the room and one for the width. (You should use the version of the FeetInches class that you created in Programming Challenge 11 with the addition of a multiply member function. You can use this function to calculate the area of the room.) The RoomDimension class should have a member function that returns the area of the room as a FeetInches object. Next, you should create a RoomCarpet class that has a RoomDimension object as an attribute. It should also have an attribute for the cost of the carpet per square foot. The RoomCarpet class should have a member function that returns the total cost of the carpet. Once you have written these classes, use them in an application that asks the user to enter the dimensions of a room and the price per square foot of the desired carpeting. The application should display the total cost of the carpet.

What were Roman Capitals first used for?

Answers

Answer:

Square capitals were used to write inscriptions, and less often to supplement everyday handwriting. When written in documents this style is known as Latin book hand. For everyday writing the Romans used a current cursive hand known as Latin cursive. Notable examples of square capitals used for inscriptions are found on the Roman Pantheon, Trajan's Column, and the Arch of Titus, all in Rome. Square capitals are characterized by sharp, straight lines, supple curves, thick and thin strokes, angled stressing and incised serifs. These Roman capitals are also called majuscules, as a counterpart to minuscule letters such as Merovingian and Carolingian.

In 2019, the tuition for a full time student is $7,180 per semester. The tuition will be going up for the next 7 years at a rate of 3.5% per year. Write your program using a loop that displays the projected semester tuition for the next 7 years. You may NOT hard code each years tuition into your program. Your program should calculate the tuition for each year given the starting tuition in 2019 ($7, 180) and the rate of increase (3.5%). You should then display the actual year (2020, 2021, through 2026) and the tuition amount per semester for that year

Answers

Answer:

In Python:

tuition = 7180

year = 2019

rate = 0.035

for i in range(2019,2027):

   print(str(year)+": "+str(round(tuition,2)))

   tuition = tuition * (1 + rate)

   year = year + 1

   

Explanation:

This initializes the tuition to 7180

tuition = 7180

This initializes the year to 2019

year = 2019

This initializes the rate to 3.5%

rate = 0.035

This iterates through years 2019 to 2026

for i in range(2019,2027):

This prints the year and tuition

   print(str(year)+": "+str(round(tuition,2)))

This calculates the tuition

   tuition = tuition * (1 + rate)

This increments year by 1

   year = year + 1

Ram and Hari can finish a piece of work in 6 days and 12 days respectively in how many days will they finish it working together

Answers

Answer:

4 days

Explanation:

Given - Ram and Hari can finish a piece of work in 6 days and 12 days

             respectively.

To find - In how many days will they finish it working together

Proof -

As given,

Ram and Hari can finish a piece of work in 6 days and 12 days respectively.

⇒1 day work of Ram done in = [tex]\frac{1}{6}[/tex]

   1 day work of Hari done in = [tex]\frac{1}{12}[/tex]

If they work together,

1 day work of both together done in = [tex]\frac{1}{6}[/tex] + [tex]\frac{1}{12}[/tex] = [tex]\frac{2 + 1}{12} = \frac{3}{12}[/tex] = [tex]\frac{1}{4}[/tex]

As we know Work is inversely proportional to efficiency

And efficiency = Person's 1 day work

As we have ,

1 day work of both together done in =  [tex]\frac{1}{4}[/tex]

⇒ Total work done in 4 days if they work together.

gesture will be based on calling the nextInt method of the given Random object. If the next integer is even, player1 will play
rock. If it is odd, player1 will play paper. Player1 never plays scissors. Player2 will play rock in the first round, paper in the
second round, scissors in the third round, and repeat the cycle starting with rock again in the fourth round. The method will sum

Answers

Answer:

The output is 5

Explanation:

Given

Dim x As Integer

x = 5

If x <=5 Then x = x + 1

Label1.text = x -1

Required

The output

On the second line of the code, x=5

The third line is an if condition which checks if x<=5

So, we have:

5 <= 5 ....This is true

So, x = x + 1 will be executed

[tex]x = 5 + 1[/tex]

[tex]x = 6[/tex]

The last line of the program subtracts 1 for x and outputs the result on Label1

Label1.text = x -1

Label1.text = 6 -1

Label1.text = 5

Hence, the output is 5
