Answer:

The solution code is written in Python 3 as below:

  1. outfile = open("greeting.txt", "w")
  2. outfile.write("Hello World")
  3. outfile.close()

Explanation:

To create a simple text file in Python, we can use Python built-in function, <em>open()</em>. There are two parameters needed for the open() function,

  1. the file name and
  2. a single keyword "w". "w" denote "write". This keyword will tell our program to create a file if the file doesn't exist.

The statement <em>open("greeting.txt", "w")</em> will create a text file named "<em>greeting.txt</em>" (Line 1)

To fill up the content in the greeting.txt, we use <em>write()</em> method. Just include the content string as the argument of the <em>write()</em> method. (Line 2)

At last, we use <em>close() </em>method to close the opened file,<em> outfile</em>. This will release the system resource from the<em> outfile.</em>

Answer:

// program in java.

import java.util.*;

// class definition

class Main

{// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

   try{

    // object to read input

Scanner scr=new Scanner(System.in);

 // ask to enter name

System.out.print("Enter Your name: ");

 // read name from user

String NAME=scr.nextLine();

// print message

System.out.println("Greetings,"+NAME);

     

   }catch(Exception ex){

       return;}

}

}

Explanation:

Read name from user with the help of scanner object and assign it to variable "NAME".Then print a Greetings message as "Greetings,NAME" where NAME will be  replaced with user's input name.

Output:

Enter Your name: Rachel                                                                                                    

Greetings,Rachel

What is the area of a parallelogram whose vertices are A(−1, 12) , B(13, 12) , C(2, −5) , and D(−12, −5) ? Enter your answer in
11Alexandr11 [23.1K]
<span>Looking at the first two vertices, A and B, we see that the x values have a difference of (-1 - 13) units, or 14 units. This gives us the base of the parallelogram. Next, we look at the difference between the y values between B and C to find the height. In this case, they are (12 - [-5] ) units, or 17 units. The area of a parallelogram is simply base multiplied by height, which is (14 * 17), or 238 square units.</span>

You are given an array x of string elements along with an int variable n that contains the number of elements in the array. You
Slav-nsk [51]

Answer:

The code to this question can be given as:

Code:

int i,j,count_previous=0,count_next=0; //define variable

for (j=0; j<n; j++) //loop for array

{

if (x[0]==x[j]) //check condition

{

count_previous++; //increment value by 1.

}

}

for (i=0; i<n; i++) //loop

{

for (j=0; j<n; j++)

{

if (x[i]==x[j]) //check condition

{

count_next++; //increment value by 1.

}

}

if (count_previous>count_next) //check condition

{

mode=x[i-1];

}

else

{

mode=x[i];

count_previous=count_next; //change value.

count_next= 0 ; //assign value.

}

}

Explanation:

In the question it is define that x is array of the string elements that is already define in the question so the code for perform operation in the array is given above. In the code firstly we define the variable that is i, j, count_previous, count_next. The variable i,j is used in the loop and variable count_previous and count_next we assign value 0 that is used for check the values of array. Then we define the for loop in this loop we use conditional statement in the if block we check that array of zero element is equal to array of j value then the count_previous is increase by 1. Then we use nested loop It is also known as loop in a loop. In this first loop is used for array and the second loop is used for check array element.In this we use the condition that if array x of i value is equal to array x of j then count_next will increment by 1.Then we use another condition that is if count_previous is greater then count_next then mode of x is decrement by 1. else mode equal to array and count_previous holds the value of count_next and count_next is equal to 0.

Svetlanka [38]

Answer:

def future_investment_value(investment, monthly_interest_rate, years):

  print("Years\tFuture Value")

  print("- - - - - - - - - - -")

  for i in range(1, years+1):

      future_value = investment * ((1 + monthly_interest_rate) ** (12 * i))

      print(i, "\t\t", format(future_value, ".2f"))

investment = float(input("Enter the invesment amount: "))

interest = float(input("Enter the annual interest rate: "))

year = int(input("Enter the year: "))

future_investment_value(investment, interest/1200, year)

Explanation:

Inside the function:

- In the for loop that iterates through the years, calculate the future value using the formula and print the results

Then:

- Ask the user for the investment, annual interest rate, and year

- Call the function with the given inputs
