A Consider the following method definition. The method printAllCharacters is intended to print out every character in str, start

ing with the character at index 0. public static void printAllCharacters (String str) for (int x = 0; x< str.length(); x++) // Line 3 System.out.print(str.substring(x, x + 1)); The following statement is found in the same class as the printAllCharacters method. printAllCharacters ("ABCDEFG"); Which choice best describes the difference, if any, in the behavior of this statement that will result from changing x < str.length() to x <= str.length() in line 3 of the method?
Α) The method call will print fewer characters than it did before the change because the loop will iterate fewer times.
B) The method call will print more characters than it did before the change because the loop will iterate more times.
C) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.
D) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 8 in a string whose last element is at index 7.
E) The behavior of the code segment will remain unchanged.

Answer:

<em>(c) The method call, which worked correctly before the change, will now cause a run-time error because it attempts to access a character at index 7 in a string whose last element is at index 6.</em>

<em />

Explanation:

Given

printAllCharacters method and printAllCharacters("ABCDEFG");

Required

What happens when  x < str.length() is changed to x <= str.length()

First, we need to understand that str.length()  gets the length of string "ABCDEFG"

There are 7 characters in "ABCDEFG".

So: str.length()  = 7

The first character is at index 0 and the last is at index 6

Next, we need to simplify the loop:

for (int x = 0; x< str.length(); x++) means for (int x = 0; x< 7; x++)

The above loop will iterate from the character at the 0 index to the character at the 6th index

while

for (int x = 0; x<=str.length(); x++) means for (int x = 0; x<=7; x++)

The above loop will iterate from the character at the 0 index to the character at the 7th index

Because there is no character at the 7th index, the loop will return an error

Hence: (c) is correct

Green computing involves reducing electricity consumed and environmental waste generated when using a computer. which of the fol
sergeinik [125]
If you want to support green computing, the most basic thing you can do is reduce your brightness. More light equals more energy consumption. That's why there are websites that are made as exact copies of other websites except they're entirely black because the color black spends less energy. You can also try to fix your things when they get broken instead of throwing them away instantly and buying a new one.

You and a few friends are having a meal at a pizza restaurant, and the server has just given you the bill. Write a function that
cestrela7 [59]

Answer:

How to calculate the total cost of the meal

For bill inclusive of tax, cost1=cost*(1+tax percentage)

For bill inclusive of tax and tip, cost2=cost1*(1+tip percentage)

Meal cost =(pizza cost*(1+tax percentage))*(1+tip percentage)

Now how to calculate the cost per person

cost per person=meal cost/ number of people.

C language code to solve the above problem is given below with appropriate comments for explanation

Explanation:

#include<stdio.h>

float split_bill(int cost,float tax)

{

//Declaring number of people as int

int number;

//Prompting for number of people

printf("Enter number of people ");

scanf("%d",&number);

//Declaring tip percentage as float

float tip_percent;

//Prompting for tip percentage

printf("Enter tip percentage between 0 and 1 ");

scanf("%f",&tip_percent);

//Calculating total meal cost

float meal=(((float)cost)*(1+tax))*(1+tip_percent);

//Printing total cost of meal

printf("Total cost of meal: %0.2f ",meal);

//Calculating cost per person

float cost_per_person=meal/number;

//Returning cost per person to main function

return cost_per_person;

}

int main()

{

//Declaring pizza cost as int and tax percentage as float

int pizza_cost;

float tax_percent;

//Prompting user for pizza cost

printf("Enter billing amount of pizza ");

scanf("%d",&pizza_cost);

//Prompting user for tax percentage

printf("Enter tax percentage between 0 and 1 ");

scanf("%f",&tax_percent);

//Printing the cost per person by calling the function split_bill

printf("Total cost per person is: %0.2f ",split_bill(pizza_cost,tax_percent));

return 0;

}
