The answer to the question is (A) overhead projector.

Since Jackson only has three employees who signed up to attend the seminar on how to file taxes, he can choose to use overhead projector in presenting his seminar. This is a better option than webcast, video conferencing, or external monitor. External monitor might be to small for him to effectively present the material to the audience, while webcast and video conferencing might be inefficient if used for something that only has a small number of audience.

KengaRu [80]

Answer:

The correct answer for the following question will be C. War driver.

Explanation:

The act of searching for network (wireless) in a moving vehicle by a person (using laptop and mobile phones) is known as War driver. We can also call it a free WiFi access point publicly.

The other three options like :

  • Key loggers (basically a software).
  • Pretexter (used for scam, getting someones personal information).
  • Phishers (used to obtain users sensitive information such as, username, password etc).

None of the option is used for networking, not able to perform such types of tasks as war driver.

So, option C is the correct answer.

#include <iostream> //defining header file

using namespace std;

void printFeetInchShort(int numFeet,int numInches); //decalring method printFeetInchShort  

void printFeetInchShort(int numFeet,int numInches)//defining method printFeetInchShort

{

cout<<"height: "; // print message

cout<<numFeet<<"\'"<<""<<numInches<<"\""; //print value

}

int main() //defining main method

{

int numFeet, numInches; //defining integer variable

cout<<"Enter height feet: "; //print message

cin>>numFeet; //input value by user

cout<<"Enter height inches: "; //print message

cin>>numInches; //input value by user

printFeetInchShort(numFeet,numInches); //calling method printFeetInchShort    

return 0;

}

Output:

Enter height feet: 5

Enter height inches: 9

height: 5'9"

Explanation:

In the above C++ language program, first, a header file is included, that uses the basic function, in the next step, the "printFeetInchShort()" method is defined, in the method two integer variables passed as a parameter, inside this method a print function "cout" is used, that print user input value with single and double quote.

Then the main method is declared, inside this method two integer variables "numFeet and numInches" are defined, which is used to take input value by user and pass the value in "printFeetInchShort()" function parameter and call the function.

Create a program that calculates the tip and total for a meal at a restaurant. Type the code into an IDLE IDE editor window and
Nataly [62]

Missing details:

The formula for calculating the tip amount is:

tip = cost of meal * (tip percent / 100)

  • The program should accept decimal entries like 52.31 and 15.5.
  • Assume the user will enter valid data.
  • The program should round the results to a maximum of two decimal places.

Answer:

In Python:

print("Tip Calculator")

cost_meal =  float(input("Enter Cost of Meal: "))

tip_percent = float(input("Enter Tip Percent: "))

tip_amount = cost_meal * tip_percent / 100

total_amount = tip_amount + cost_meal

print("Tip amount:   "+str(round(tip_amount,2)))

print("Total amount:   "+str(round(total_amount,2)))  

Explanation:

This line prints the string "Tip "Calculator"

print("Tip Calculator")

This lime prompts user for cost of meal

cost_meal =  float(input("Enter Cost of Meal: "))

This lime prompts user for tip percemtage

tip_percent = float(input("Enter Tip Percent: "))

This line calculates the tip amount

tip_amount = cost_meal * tip_percent / 100

This line calculates the total amount

total_amount = tip_amount + cost_meal

This line prints the tip amount

print("Tip amount:   "+str(round(tip_amount,2)))

This line prints the total amount

print("Total amount:   "+str(round(total_amount,2)))
