Most modern text editors are able to give some statistics about the text they are editing. One nice statistic is the average word length in the text. A word is a maximal continuous sequence of letters ('a'-'z', 'A'-'Z'). Words can be separated by spaces, digits, and punctuation marks. The average word length is the sum of all the words' lengths divided by the total number of words.

For example, in the text "This is div2 easy problem". There are 5 words: "This"is"div"easy" and "problem". The sum of the word lengths is 4+2+3+4+7 = 20, so the average word length is 20/5 = 4.

Given a text, return the average word length in it. If there are no words in the text, return 0.0.

Input
The first line will contain the text of length between 0 and 50 characters inclusive. Text will contain only letters ('a'-'z', 'A'-'Z'), digits ('0'-'9'), spaces, and the following punctuation marks: ',', '.', '?', '!', '-'. The end of text will be marked with symbol '#' (see examples for clarification).

Output
Output should contain one number - the average length. The returned value must be accurate to within a relative or absolute value of 10^-9.

C++, Need to create a code that will calculated the statistics for character input?

This is the prompt for the code. I truly understand nothing of what it's asking.

Ask the user for one character (terminated by a carriage return).Using flow control, classify the character into one of these categories:

1)           vowel

2)           consonant

3)           digit (0-9)

4)           other

Output the character input, its numeric decimal value, and the classification. Total up the number of each type of character entered. After the character is entered, ask the user if they want to continue (Y/N). When they enter N, you can stop prompting for more characters. Make sure to validate for Y or N data entry. Then display the total number of each type of characters entered.

In java please, thank you :) For this assignment, you will continue your practice with dynamic structures. Specifically, you will be implementing a different version of a linked-list, called a Queue. Queues are very important and useful linear structures that are used in many applications. Follow the link below for a detailed description:

tutorialspoint - Queue (Links to an external site.)

The queue description above uses an array implementation for examples. As usual you will be not be using arrays, you will be using linked-lists. Specifically a singly-linked list.

Our job will be to implement the four basic queue methods which are enqueue(), dequeue(), peek() and isEmpty() as described in the tutorial mentioned above. You will not need to implement the isFull() method since we will be using linked-lists and linked-lists are theoretically never full.

For this assignment we will need to implement an uncommon version of enqueue(). In our version, if the element that is being processed is already in the queue then the element will not be enqueued and the equivalent element already in the queue will be placed at the end of the queue.

Additionally, you will be implementing a special kind of queue called a circular queue. A circular queue is a queue where the last position is connected back to the first position to make a circle. Therefore it does not have the traditional front and back data elements. It only has one data element, called rear that keeps track of the last element in the queue.

This structurally similar to a circular singly-linked list described here:

tutorialspoint - Circular Linked List (Links to an external site.)

The program's input will a single string that consists of single-character elements. You program will process each character in the string according the descriptions below. Where "->" signifies the front of the queue (blue designates input, red designates output):

• 'A' - 'Z': Puts the character on the queue.

  ABCD
  (nothing will be outputted)
  
  ABCDA* 
  B C D A

• '*': displays the elements of the queue separated by a space.

  ABCD*
  -> A B C D
  

• '$': prints the element at the front of the queue.

  ABCD$
  peek: A 
  

• '#': empties out the queue.

  ABCD#*
  -> 
  

• '!': deletes an element from the queue.

  ABCD!*
  -> B C D
  

• all other characters: prints an error message for each element, does not put the element in the queue and clears the queue.

  a
  The illegal character 'a' was encountered in the input stream. 

Programming Notes:

1. You can not delete any code in the Queue class.
2. If you need additional methods you must add them to the MyQueue class.
3. If you do not need any additional methods then you can delete the myQueue class.
4. You must use a singly-linked list with only a rear pointer.
5. Do not assume any maximum length for any input string.
6. You need not test for the null or empty string ("") cases.

Programming Rules:

1. You are not allowed to add any arrays or ArrayLists or any Java built-in (ADTs), such as Lists, Sets, Maps, Stacks, Queues, Deques, Trees, Graphs, Heaps, etc. Or add any class that inherits any of those ADTs.
2. For your node and list class you can use the code that was used in the book, video and lecture notes related to the node and lists class examples.
3. You are not allowed to use Java Generics.
4. If hard-coding detected in any part of your solution your score will be zero for the whole assignment.  

Please use started code:

    2.4) Why do we need these two modes in designing an operating system?

A byte is made up of 8 bits although a byte is rarely represented as a string of binary digits or bits. Instead, it is typically presented as a pair of hexadecimal digits where each digit represents 4 bits or half a byte or "nibble." We have been reading in hex digits and outputting their decimal value, but what we really want to do is create a byte from a pair of hex digits read from input.

Create a C program that:

1. Reads a pair of hexadecimal characters from input. For example: 3B or CF.
2. Converts each of them into their decimal value. For example: 3 (0011 in binary) and 11 (1011 in binary)
3. Packs the two nibbles into a single byte. For example, 3 and B packed into an 8 bit byte would be 0011 1011.
4. Outputs the merged byte in hexadecimal to verify that the byte was packed correctly.

The printf() function supports outputting an integer as a hexadecimal number using the %x (where the hexadecimal letters are presented in lower-case) and %X (where the hexadecimal letters are presented in upper-case).

To pack two integers that have values represented with only 4 bits, you need to perform two operations with the integers:

1. Shift the integer holding the decimal value of the first hexadecimal digit in the pair to the left 4 bits.
2. OR the integer holding the decimal value of the second hexadecimal in the pair with the shifted integer.

After the shift and the OR, the first integer will not have the lower 8 bits (byte) set to the values represented by the two characters read from input.

Write a program that uses a two dimensional array to store the highest and lowest temperatures for each month of the calendar year. The temperatures will be entered at the keyboard. This program must output the average high, average low, and highest and lowest temperatures of the year. The results will be printed on the console. The program must include the following methods:

• A method named inputTempForMonth whose purpose is to input a high and a low temperature for a specific month. The month and the array of temperatures will both be passed as input arguments to the method. The method will not have a return value.
• A method named inputTempForYear whose purpose is to input a high and a low temperature for every month of the year. There are no input arguments for this method, but the method does return a completed multidimensional array of temperatures for the year.
• A method named calculateAverageHigh whose purpose is to calculate the average high temperature for the year. This method will take the array of temperatures as input and will return the average high temperature for the year.
• A method named calculateAverageLow whose purpose is to calculate the average low temperature for the year. This method will take the array of temperatures as input and will return the average low temperature for the year.
• A method named findHighestTemp whose purpose is to return the index value of the highest temperature for the year. If the highest temperature of the year occurs more than once in the year, then the method should return the index of the first month that had the temperature. The method will take the array of temperatures as an input argument and return the index of the highest temperature.
• A method named findLowestTemp whose purpose is to return the index value of the lowest temperature for the year. If the lowest temperature of the year occurs more than once in the year, then the method should return the index of the first month that had the temperature. The method will take the array of temperatures as an input argument and return the index of the lowest temperature.
• A main method that uses the previous methods to determine the average high temperature, average low temperature, and highest and lowest temperatures for the year. The main method must print out these average temperatures as well as the month and temperature for the highest and lowest temperatures for the year.
