Answer:
import string
dic = {}
book=open("book.txt","r")
# Iterate over each line in the book
for line in book.readlines():
tex = line
tex = tex.lower()
tex=tex.translate(str.maketrans('', '', string.punctuation))
new = tex.split()
for word in new:
if len(word) > 2:
if word not in dic.keys():
dic[word] = 1
else:
dic[word] = dic[word] + 1
for word in sorted(dic):
print(word, dic[word], '\n')
book.close()
Explanation:
The code above was written in python 3.
<em>import string </em>
Firstly, it is important to import all the modules that you will need. The string module was imported to allow us carry out special operations on strings.
<em>dic = {} </em>
<em>book=open("book.txt","r") </em>
<em> </em>
<em># Iterate over each line in the book</em>
<em>for line in book.readlines(): </em>
<em> </em>
<em> tex = line </em>
<em> tex = tex.lower() </em>
<em> tex=tex.translate(str.maketrans('', '', string.punctuation)) </em>
<em> new = tex.split() </em>
<em />
An empty dictionary is then created, a dictionary is needed to store both the word and the occurrences, with the word being the key and the occurrences being the value in a word : occurrence format.
Next, the file you want to read from is opened and then the code iterates over each line, punctuation and special characters are removed from the line and it is converted into a list of words that can be iterated over.
<em />
<em> </em><em>for word in new: </em>
<em> if len(word) > 2: </em>
<em> if word not in dic.keys(): </em>
<em> dic[word] = 1 </em>
<em> else: </em>
<em> dic[word] = dic[word] + 1 </em>
<em />
For every word in the new list, if the length of the word is greater than 2 and the word is not already in the dictionary, add the word to the dictionary and give it a value 1.
If the word is already in the dictionary increase the value by 1.
<em>for word in sorted(dic): </em>
<em> print(word, dic[word], '\n') </em>
<em>book.close()</em>
The dictionary is arranged alphabetically and with the keys(words) and printed out. Finally, the file is closed.

Answer:
see explaination
Explanation:
Code below:
#include"letters.h"
int main()
{
while(1)
{
int input;
//Asks the user to enter 1 or 2 to see if the letter is a consonant
//of vowel.
printf("Enter 1 to check vowel or 2 for consonant:");
//scans inputted number
scanf("%i", &input);
//if the input is 1 then it will ask the user to enter the letter
//they want to test.
if(input == 1)
{
char c;
printf("Enter a character to test if it's a vowel:");
scanf(" %c",&c);
//if it is a vowel, then it will print that the letter is a vowel
if(is_vowel(c))
{
printf("%c is a vowel.\n", c);
}
//if not, then it will print that it isn't a vowel
else
{
printf("%c is not a vowel.\n", c);
}
}
//if the user inputs 2, then it will ask the user for the letter to test if
//it's a consonant or not.
else if(input == 2)
{
char c;
printf("Enter a character to test if it's a consonant:");
scanf(" %c",&c);
//if it is a consonant, then it will print that the letter is a consonant
if(is_h_consonant(c))
{
printf("%c is a consonant.\n", c);
}
//if not, then it will tell the user that it isn't a consonant
else{
printf("%c is not a consonant.\n", c);
}
}
else{
break;
}
}
return 0;
}
