Answer:

Explanation:

C.argv[0]: "program.py"

argv[1]: "-r"

argv[2]: "input.dat"

argv[3]: "output.dat"

is the right answer. as 0 argument is always the script. We can find this by importing sys and using the command sys.argv. And like len(sys.argv) will give total number of arguments.

To protect the computer network of a large organization, network engineers monitor network traffic. Malware detection method of data mining best being used to protect the network.

Explanation:

Data mining has excellent potential as a malware detection tool. It allows us to analyze vast sets of information and gives an opportunity to extract new data from it. It also provides the ability to identify both known and zero-day attacks.

Write a program that asks the user how many numbers will be entered and then has the user enter those numbers. When this is done

KATRIN_1 [288]

Answer:

The program written in Python 3 is as follows;

The program does not make use of comments; however, see explanation section for detailed line by line explanation of the program

num = int(input("Number of Inputs: "))

mylist = []

userinput = int(input("Enter a digit: "))

i = 1

while i < num:

mylist.append(userinput)

userinput = int(input("Enter a digit: "))

i += 1

try:

first7 = mylist.index(7)+1

print('The first position of 7 is ',first7)

last7 = num - 1 - mylist[::-1].index(7)

print('The last position of 7 is ',last7)

except:

print('7 is not on the list')

Explanation:

This line prompts user for the number of inputs

num = int(input("Number of Inputs: "))

This line declares an empty list

mylist = []

This line inputs the first number into the empty list

userinput = int(input("Enter a digit: "))

The italicized lines represent an iteration that allows user to input the numbers into the empty list.

i = 1

while i < num:

mylist.append(userinput)

userinput = int(input("Enter a digit: "))

i += 1

The try-except is used to check the presence of 7 in the list

try:

This checks the first occurrence of 7

first7 = mylist.index(7)+1

This prints the first occurrence of 7

print('The first position of 7 is ',first7)

This checks the last occurrence of 7

last7 = num - 1 - mylist[::-1].index(7)

This prints the last occurrence of 7

print('The last position of 7 is ',last7)

The following is executed if there's no occurrence of 7

except:

print('7 is not on the list')

In Java.Use a single for loop to output odd numbers, even numbers, and an arithmetic function of an odd and even number. Use the

rosijanka [135]

Answer:

This program is written using java programming language

Difficult lines are explained using comments (See Attachment for Source file)

Program starts here

import java.util.*;

import java.lang.Math;

public class oddeven{

public static void main(String [] args)

{

double even,odd;//Declare variables even and odd as double

//The next iteration prints odd numbers

for(int i = 1;i<=173;i+=2)

{

odd = i;

System.out.format("%.4f",odd);//Round to 4 decimal places and print

System.out.print("\t");

}

System.out.print('\n');//Start printing on a new line

//The next iteration prints even numbers

for(int i = 0;i<=173;i+=2)

{

even=i;

System.out.format("%.4f",even);//Round to 4 decimal places and print

System.out.print("\t");

}

System.out.print('\n');//Start printing on a new line

double ssqrt;//Declare ssqrt to calculate the square root of sum of even and odd numbers

for(int i = 0;i<=173;i+=2)

{

ssqrt = Math.sqrt(2*i+1);//Calculate square root here

System.out.format("%.4f",ssqrt); //Round to 4 decimal places and print

System.out.print("\t");

}

Explanation:

Libraries are imported into the program

import java.util.*;

import java.lang.Math;

The following line declares variables even and odd as double

double even,odd;

The following iteration is used to print odd numbers with in the range of 0 to 173

for(int i = 1;i<=173;i+=2) {

odd = i;

System.out.format("%.4f",odd); This particular line rounds up each odd numbers to 4 decimal places before printing them

System.out.print("\t"); This line prints a tab

}

The following code is used to start printing on a new line

System.out.print('\n');

The following iteration is used to print even numbers with in the range of 0 to 173

for(int i = 0;i<=173;i+=2)

{

even=i;

System.out.format("%.4f",even); This particular line rounds up each even numbers to 4 decimal places before printing them

System.out.print("\t"); This line prints a tab

}

The following code is used to start printing on a new line

System.out.print('\n');

The next statement declares ssqrt as double to calculate the square root of the sum of even and odd numbers

double ssqrt;

for(int i = 0;i<=173;i+=2)

{

ssqrt = Math.sqrt(2*i+1);This line calculates the square root of sum of even and odd numbers

System.out.format("%.4f",ssqrt); This particular line rounds up each even numbers to 4 decimal places before printing them

System.out.print("\t"); This line prints a tab
