<span>2. basketball
This is a classic case of overloading in C++. You have 2 functions, both named "printSport", but one of the functions receives an input of type double, and the other receives an input of type int. The specified method call passes a parameter of type int, so the version of printSport is called that receives a parameter of type int. And that version of printSport only prints the word "basketball". The other version of printSport is never called at all.</span>
Answer:
C) A quarter was worth less than is used to be.
Explanation:
I got this answer wrong when I chose B.
Answer:
D) Hex Pane.
Explanation:
Hex Pane is the bottom pane where whole information in the packet is shown in hexadecimal format on the left and also in character when possible and decimal also.It is the bottom pane of Wireshark window.
So we can say that Hex pane is referred to the bottom pane of the Wireshark window which displays the information in hexadecimal on the left .
Answer:
b. data type of arguments
Explanation:
One of the ways to overload a method is using different type of arguments. Let's say we have a method that finds and returns two integer values
public int sumValues(int num1, int num2){
return num1 + num2;
}
We can overload this method by passing double values as arguments
public double sumValues(double num1, double num2){
return num1 + num2;
}
Answer:
- import statistics
- def st_dev(file_name):
- with open(file_name) as file:
- data = file.readlines()
- numList = []
- for x in data:
- numList.append(int(x))
-
- return statistics.pstdev(numList)
- print(st_dev("text1.txt"))
Explanation:
The solution code is written using Python.
To ease the calculation task, we can import Python statistics module to use the pstdev method to calculate the population standard deviation of a list of numbers (Line 1).
Next, create a st_dev function that take single argument file_name (Line 3). In the function, it will open the input file and read the data line by line (Line 4-5). Create a for loop to traverse through each line of the data which is an integer and append it to numList (Line 7-8). We can pass the numList to pstdev method (Line 10) and return the resulting standard deviation value as output.
We test the function by passing a file which hold a list of integer values in each line (Line 12).
