Answer:

Please find the edited program below:

#include<iostream>

#include <stdio.h>

using namespace::std;

int main()

{

char ch;

cout<<"Enter any letter: ";

ch=getchar();

if(ch=='a' || ch=='e' || ch=='i' || ch=='o' || ch=='u'|| ch=='A' || ch=='E' || ch=='I' || ch=='O' || ch=='U')

cout<<"Vowel";

else

cout<<"Consonant";

return 0;

}

Explanation:

We cannot input char type using cin, we need to use getchar, and it is under header file stdio.h. Also, for comparing we need to use == and not =. And corrrect way of including std is using namespace::std;

Write a Python 3 program to read from a .csv file containing rates from power companies. Your program should determine the avera

aliya0001 [1]

Answer:

In python:

file = open("rates.csv", "r")

ratecount = 0

ratesum = 0

mylist = []

rates = file.readlines()

for nums in rates:

num = nums.rstrip('\n')

mylist.append(int(num))

for i in num:

ratesum= ratesum + int(i)

ratecount = ratecount + 1

print("Maximum Rate: "+str(max(mylist)))

print("Minimum Rate: "+str(min(mylist)))

print("Average Rate: "+str(ratesum/ratecount))

Explanation:

This opens the csv file

file = open("rates.csv", "r")

This initializes the number of rates in the file

ratecount = 0

This initializes the sum of the rates

ratesum = 0

This initializes an empty list

mylist = []

This reads the rates into lines

rates = file.readlines()

This iterates through the rates (as a string)

for nums in rates:

This removes the newline character \n in the rates

num = nums.rstrip('\n')

This appends the rates (as an integer) to the empty list

mylist.append(int(num))

The following counts the rates in the file and also sum them up

for i in num:

ratesum= ratesum + int(i)

ratecount = ratecount + 1

This prints the maximum of the rates

print("Maximum Rate: "+str(max(mylist)))

This prints the minimum of the rates

print("Minimum Rate: "+str(min(mylist)))

This calculates and prints the average rate

print("Average Rate: "+str(ratesum/ratecount))

Just five types of pointing device,list

posledela

Answer:

five types of pointing devices

Explanation:

Ponting devices

Pointing means point something and the pointing devices are the input /peripheral devices those are used to point the pointer on the screen. We do move cursor on the screen to open the files or any icon.

There are many types of pointing devices but these are quite common which are given below

Computer mouse
Finger on touch screen.
Joystick.
Leap Motion.
Light pen (pen)

1.Mouse

Mouse is most common type of input device that is used for pointing the data on the screen. We press it with our hands and keep pointing the things.

There are three types of mouse

optical mouse
wireless mouse
trackball mouse.

2. Finger on touch screen

In this type of movement the fingers are input devices those we use to see the movement of pointer on the screen and this is most common in this century.

3.Joystick.

Joystick is another input device to point the cursor but it is mostly used in games. Children can use it smartly so it is inculcated in games usually.

4. Leap Motion

The Leap Motion (LM) controller is a latest 3D sensing device for hand posture interaction with a computer. It is having the capability sense the location of the fingers of the hands, as well as the palm position.

5.Light Pen

this is another pointing device which is mostly used to highlight and select the data on the screen.

Note: All of these above pointing devices are most common used now a days. These devices are having new conventions day by day for the ease of user. This era is basically the era of IT ,so the use of computer must be so easy and conventional for the user so, the innovations and improvement in such devices is made side by side.

3. What are two reasons for versioning your still life project file? (1.0 points)

inna [77]

Answer:

The project file can be managed by making its multiple version due to the following reasons.

1. We can create multiple copies or version of the project to avoid any unfortunate circumstance such as Project file can be corrupted or can be deleted. In that case we can use the other version of that project file.

2. When we are working on some project, we are modifying the code or program to achieve our desired results. In this process we may forgot the changes that we have made while modification. If we does not obtain our desired results while modification that can lead to losing the original file. To reduce this type of risk we create multiple versions of project File.

3. We also create version of our project files on some internet drives as a backup. In case our computer has lost or operating system has been corrupted. A version of our project file is available on Internet drives such as Google drive or Drop box.

Pass the two arrays to a method that will display the integer value(s), if any, that appear in both arrays (note that the two ar

vampirchik [111]

Answer:

The solution code is written in Java

public static void checkCommonValues(int arr1[], int arr2[]){
if(arr1.length < arr2.length){
for(int i = 0; i < arr1.length; i++){
for(int j = 0; j < arr2.length; j++){
if(arr1[i] == arr2[j]){
System.out.print(arr1[i] + " ");
}
}
}
}
else{
for(int i = 0; i < arr2.length; i++){
for(int j = 0; j < arr1.length; j++){
if(arr2[i] == arr1[j]){
System.out.print(arr2[i] + " ");
}
}
}
}
}

Explanation:

The key idea of this method is to repeated get a value from the shorter array to check against the all the values from a longer array. If any comparison result in True, the program shall display the integer.

Based on this idea, an if-else condition is defined (Line 2). Outer loop will traverse through the shorter array (Line 3, 12) and the inner loop will traverse the longer array (Line 4, 13). Within the inner loop, there is another if condition to check if the current value is equal to any value in the longer array, if so, print the common value (Line 5-7, 14-16).

solong [7]

Answer:

please find the attachment of the flowchart.

Explanation:

In this question, a start block is used to start the program, in the parallelogram box we input the value from the user end and in the diamond box, we check the input is not equal to 0. In the next diamond box, it checks the given input value and print value, and at the last, we stop the code.

Please find the program and its output in the attached file.
