Write a C program to print the given X number pattern series Your program should ask for a single input- the number, which will be a digit from 1-9 (if the number is not within the range, the program will terminate) o e.g., if the user enters 10, or -1, the program will terminate. Then output the number and in the line below, the corresponding X pattern onto a file. The output filename is 'CP3out.txt'. Please leave 2 lines in between successive outputs for clarity. Note:. The appearance of the X: your output must match the examples below. Also note that your code must not hard code the output corresponding to each individual number (1-9) but rather, be general .

Write a program which reads the content of a file given as input and counts the number of thewords in the file. It is assumed the words are separated by one or multiple of the followingcharacters: ’ ’ ’,’ ’?’ ’!’ ’.’ ’\t’ ’\r’ ’\n’.  input: words.txt output: The file contains 17 words. Please write in C programming language.

Create a new file (in Dev C++) and save it as lab7_XYZ.cpp (replace XYZ with your initials). In Lab 2, you created a menu for a simple calculator program. In Lab 6, you added some functionality based on the user selection. In this lab, you will add some more functionality to the program. Use loops to keep running the program until the user chooses the exit condition (9). When dividing, use a loop to validate user input, making sure the denominator (second number) is not zero. If the user enters a 0 for the second number, display an error message and keep prompting until a non-zero number is entered. 1)   Add two numbers2)   Subtract two numbers3)   Multiply two numbers4)   Divide two numbers 9)   Exit program The program should: contain header comments as shown in class display a hello message before presenting the menu display the menu prompt user for selection echo the selection back to the user if the selection was invalid, display error message to user and then loop back to menu…

Design a modular program in Python to process payroll for all hourly paid employees, save all the data into a text file and make a backup file as well. The program should allow user enter each employee's ID, name, hours worked, and hourly pay rate. And then calculate gross pay with overtime hours(hours beyond 40) paid 50% more. And then the program should display pay statement for each employee and store them into a same text file. The program should display total number of employees, total number of hours worked by all employees, and total gross pay and save them at the end of the same text file as well. The program should contain the following functions: main(), get_employee_info(), calc_gross_pay(hours, rate), display_pay_statement(emp_id, emp_name, hours_horked, hourly_pay_rate, gross_pay), save_pay_statement_to_file(file_object, emp_id, emp_name, hours_worked, hourly_pay_rate, gross_pay), save_summary_to_file(file_object, number_of_employees, total_hours_worked, total_gross_pay).…

Write a program that asks the user for a file name and a string to search for. The program should search the file for every occurrence of a specified string. When the string is found, the line that contains it should be displayed. After all the occurrences have been located, the program should report the number of times the string appeared in the file.

This is phython not Java Lab:  Write a file copying program.  The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file).  The program opens the source file for reading and the destination file for writing.  As the program reads each line from the source file and it writes the line to the destination file.  When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file.  Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to  : add-copy.py Copy is successful.   Source file: add.py print("This program adds two numbers")   a = int(input("Enter first number: ")) b = int(input("Enter second number: "))   print(f"{a} + {b} = {a+b}")   Destination…

Write a C++ program that reads text from a file called letter_count.txt. The program determines which alphabetic character occurs most frequently in the text and which alphabetic character appears least frequently in the text. Your program must: 1. Read each line of the file, no matter how many lines there are.2. Display an appropriate message if the letter_count.txt file is not found.3. Count both lower case and upper case variants as the same character. In the text, “Now is the time for all good men to come to the aid of their country”, the letter T occurs 7 times.4. Ignore non-alphabetic characters, such as space, period, apostrophe, etc.5. Display the most common letter in the file and its number of occurrences.6. Display the least common letter in the file and its number of occurrences.7. If there is a tie for the most (or least) common letter, the program only needs to display one of the letters which was most (or least) common.8. For this program, only the C++ string class may…
