Write a program that first reads in the name of an input file, followed by two strings representing the lower and upper bounds of a search range. The file should be read using the file.readlines() method. The input file contains a list of alphabetical, ten-letter strings, each on a separate line. Your program should output all strings from the list that are within that range (inclusive of the bounds).
Ex: If the input is:
input1.txt ammoniated millennium
and the contents of input1.txt are:
aspiration classified federation graduation millennium philosophy quadratics transcript wilderness zoologists
the output is:
aspiration classified federation graduation millennium
Notes:
There is a newline at the end of the output.
input1.txt is available to download.
In the tests, the first word input always comes alphabetically before the second word input.

Write a program that reads a file of numbers of type int and writes all the numbers to another file, but without any duplicate numbers.
Assume that the numbers in the input file are already ordered from smallest to largest. After the program is run, the new file will contain all the numbers in the original file, but no number will appear more than once in the file. The numbers in the output file should also be sorted from smallest to largest. Your program should obtain both file names from the user
Write a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name (the key field), merge the information as shown below.
File 1 and file 2 are supplied.
Here is an algorithm to merge the data from two files:
Read a line from each data file
While the end of both files has not been reached
While the end of both files has not been reached
Write the line from file 1 to the output file and read a new line from file 1.
Else
Write the line from file 2 to the output file and read a new line from file 2.
Write the remaining lines (if any) from file 1 to the output file.
Write the remaining lines (if any) from file 2 to the output file.
See the Merging Filesslides attachedto the project in Canvasfor a visual look at this algorithm.

Then program counts the occurrence of each word in the paragraph(s) and stores all words with their number of occurrences.

- You are required to implement a program which will read in a text file (.txt) containing words which are arranged in sentences. Your program should first ask the user for the name of the file and then count the number of individual words and characters (including numbers and punctuation) in the file. The word and character count result should be printed on the screen. Furthermore, your program should count the number of individual words starting with the letter 'A', 'B', 'C' and so on to 'Z'. Again, these statistics should be printed on the screen. Your program should display the letter that appears at the start of most words. The program must be written in C. You should illustrate the operation of your program by generating a text file containing 3 sentences from a lead news story on the day of testing.arrow_forwardA file words.txt contains a large number of English Language words, one per record. Write a program that uses this file to implement a simple word checker. First, read all the words into a collection. Then, using this collection find the average length of all the words and write this number to the console.Finally, using a text file that contains written English paragraphs, the program should examine each word of each line and output to the console all the words that are not in the collection as potentially misspelled words. Write to the console how many words in this text file are above the average length of the dictionary words computed above.arrow_forwardWrite a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates. Ex: If the input is: inputl.csv and the contents of input1.csv are: hello, cat,man, hey, dog, boy, Hello, man, cat,woman, dog, Cat, hey, boy the output is: hello 1 cat 2 man 2 hey 2 dog 2 boy 2 Hello 1 woman 1 Cat 1 Note: There is a newline at the end of the output, and input1.csv is available to download. 339092.2126252.ax3zav7arrow_forward

Find a Klingon word that starts with the chosen consonant (the text file contains only one word that starts with any given consonant, so you don’t need to use the random library) 3.
