The primary reason that you would import data into a database is because the data already exists somewhere else.

As an example, you may have a spreadsheet that contains names and telephone numbers of a group of people. It is much faster to import this data into a database instead of manually entering the information.

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

ozzi

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

Assume that a boolean variable workedOvertime has been declared, and that another variable, hoursWorked has been declared and in

meriva

Answer:

The c++ program to show the use of Boolean variable is given below.

#include <iostream>

using namespace std;

int main() {

int hoursWorked = 44;

bool workedOvertime;

cout<<"This program shows the use of boolean variable." <<endl;

// overtime refers to working hours more than 40 hours

if(hoursWorked > 40)

{

workedOvertime = true;

cout<<"The value of boolean variable workedOvertime is true or "<<workedOvertime<<endl;

}

// if working hours are less than or equal to 40, overtime is not considered

else

{

workedOvertime = false;

cout<<"The value of boolean variable workedOvertime is false or "<<workedOvertime<<endl;

}

return 0;

}

OUTPUT

This program shows the use of boolean variable.

The value of boolean variable workedOvertime is true or 1

Explanation:

This program uses a boolean variable to indicate the overtime of working hours.

The boolean variable is declared as shown.

bool workedOvertime;

The working hours is stored in an integer variable which is declared and initialized within the program itself.

int hoursWorked = 44;

Depending on the value of working hours, the boolean variable is assigned the value true or false.

if(hoursWorked > 40)

{

workedOvertime = true;

cout<<"The value of boolean variable workedOvertime is true or "<<workedOvertime<<endl;

}

else

{

workedOvertime = false;

cout<<"The value of boolean variable workedOvertime is false or "<<workedOvertime<<endl;

}

The value of boolean variable is displayed to the user.

In the above program, the working hours are 44 which is more than normal working hours of 40. Hence, boolean variable is assigned value true.

This program does not accept user input for working hours as stated in the question. Since value of working hours is not accepted from the user, there is no logic implemented to check the validity of the input.

This program can be tested for different values of working hours to test for the boolean variable.
