TiliK225 [7]

Answer:

See Explanation Below

Explanation:

// C++ printNumPattern() recursive method

// Comments are used for explanatory purpose

// Only the recursive is submitted

// Method starts here

void printPattern(int num1, int num2, bool dec)

{

// Print num2.

cout << num2 << " ";

//Printing to num1

if (dec == false && num1 ==num2) {

return; }

// Printing to 0 or negative.

if (dec)

{

// If num2 is greater than num2

if (num2-num1 > 0)

printPattern(num1, num2-num1, true);

else // recur with false dec

printPattern(num1, num2-num1, false);

}

else // If dec is false.

printPattern(num1, num2+num1, false);

}

//End of recursive

Which data type change will require the app builder to perform the additional steps in order to retain existing functionalities?

Readme [11.4K]

Answer:

Option D is the correct option.

Explanation:

The following option is correct because the lead alteration from number to text and the number to text types of data will reconstruct the important number of the app builder to accomplish those steps which is extra to continue to have that functionality which is in the existence. That's why the app builder has to be reconstructed the types of data for the custom fields.

In this lab, you use the pseudocode in figure below to add code to a partially created Python program. When completed, college a

Elza [17]

Answer:

Python code is given below with appropriate comments

Explanation:

#Prompt the user to enter the test score and class rank.

testScore = input()

classRank = input()

#Convert test score and class rank to the integer values.

testScore = int(testScore)

classRank = int(classRank)

#If the test score is greater than or equal to 90.

if(testScore >= 90):

#If the class rank is greater than or equal to 25,

#then print accept message.

if(classRank >= 25):

print("Accept")

#Otherwise, display reject message.

else:

print("Reject")

#Otherwise,

else:

#If the test score is greater than or equal to 80.

if(testScore >= 80):

#If class rank is greater than or equal to 50,

#then display accept message.

if(classRank >= 50):

print("Accept")

#Otherwise, display reject message.

Which of the following is a job that does not lend itself to telecommuting?

jonny [76]

Answer:

a car salesman who demonstrates the features of a new model of car

Explanation:

Telecommuting can be defined as the process or making use of a telephone, email, or the internet to achieve your daily work. An attorney that spends most of her time researching on the computer is making use of an internet to do her work and hence telecommuting is employed. A copywriter for an advertising firm also makes use of email in the process of write copying and hence telecommuting is employed. A telemarketer uses the telephone and a product support who handles queries sent by customers also uses the internet and emails and telephones and hence they all use telecommuting. Demonstrating the feature of a new car does not use require the use of a telephone, email, or the internet.

Which of the following is not true of how computers represent complex information

mote1985 [20]

Answer: c. Depending on context the same sequence of bits may represent different types of information.

Explanation:

The options for the question are:

A. Computing devices use patterns of bits to represent complex information

B. Abstraction helps represent complex information by surfacing complexity that might otherwise be hidden

C. Depending on context the same sequence of bits may represent different types of information

D. Common abstractions that are represented by computing devices include numbers, characters, and color.

The following are true of how computers represent complex information:

• Computing devices use patterns of bits to represent complex information

• helps represent complex information by surfacing complexity that might otherwise be hidden

• Common abstractions that are represented by computing devices include numbers, characters, and color.

Therefore, the option that is not true of how computers represent complex information is that "depending on context the same sequence of bits may represent different types of information".
