The name of the input file and the output file are to be passed as command line arguments. Assume there are only ASCII characters in the input file. The length of the input file is not known beforehand. So make sure your program keeps reading bytes until EOF is reached. Use the library function toupper to concert letters into uppercase. Example: The program is run from the command line as follows; C:\>toupper.exe infile.txt outfile.txt Suppose the contents of the input file infile.txt is: AbcdefG The contents of the output file outfile.txt should be: ABCDEFGWrite a C program that, given a text file, constructs Huffman code based on the character frequencies of the file and then encodes the file accordingly. The executable must accept the following command line options:• -i filename for the input file • -o filename for the output file Use the fread function, use FILE, size, etc. Please use the following to write the code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <getopt.h>

- Our requirement is to keep information of students who are taking “Introduction to Python” in Fall-2021 in a text file named ‘Students.txt’. The first line of text in this file will be header line as follows Write a python code that: Takes StudentID from user as input in a variable ‘inputID’, reads the file line by line and displays the header line and student information when inputID is found in Students.txt, otherwise display a message ‘Record not found in Students.txt’Write a C++ program that counts the number of non white-space characters in an input text file. Program takes as command argument(s) the name of the input file (and the output file with option -f). Based on the option flags, it displays the output on the standard output, or writes the output to an output file. The command format is as follows:command -f inputfile outputfile or, command -s inputfile -f indicates writing to an output file;-s indicates displaying the output on the screen. Also notice the errors caused by incomplete arguments. Including: (1) The name of the author of the program (your name) and the date it was written, (2) a concise description of what the program does, (3) a clear description of its limitations if it does not meet all specifications, and (4) explanation for critical code and data declarations. The same should also be done for each function written in the program.For an e-Shop, there is a Customer whose data is stored in a file ‘Customers.txt’, where ID, Name, Phone, Address, Email and AmountBalance. When the customer buys a product and pays from his AmountBalance, the system checks his balance and deducts if enough amount is there. Otherwise the customer receives a message “You don’t have sufficient Balance in your wallet”. Write python code to create a ‘Customers.txt’ file with at least one customer’s record. Write a function pay(), that takes amount as an input, reads the file and gets AmountBalance, print “Successful Transaction” when payment can be made or a message “You don’t have sufficient Balance in your wallet”. Write a function checkBalance(), that reads the file and gets AmountBalance, prints “Amaount Balance” Write a function recharge(), that takes “Enter Amount you want to recharge”, reads the file and gets AmountBalance, adds the new amount in AmountBalance, update the file and prints “Success”
