Question: Write a program that reads a series of dates in day/month format, from the file datesin.txt, and checks to see if the dates are valid. For each date entered, the program prints to an output file called datesout.txt whether the date is valid or not and finally the total number of valid dates. Note: Jan, Mar, May, Jul, Aug, Oct, and Dec have 31 days each. Feb has 28 days, while Apr, Jun, Sep, and Nov have 30 days each. For example, if the input file datesin.txt contains: 12/12 21/4 30/2 31/5 12/9 1/13 31/9 then datesout.txt must contain: The date 12/12 is valid! The date 21/4 is valid! The date 30/2 is Invalid! The date 31/5 is valid! The date 12/9 is valid! The date 1/13 is invalid! The date 31/9 is invalid! There were 4 valid dates in the file! NOTE: Your program must check the existence of the input file, and print the following message in case the file is missing: The input file does not exist! Copy and paste your program into the box below.

Given a text file containing unknown number of lines, each line containing three integer values representing the height of a building in (Yard foot inches) separated by space. Write a well-documented C++ program that Reads the three values from the file, If any of the read values is greater than 2000, prints on the screen an error message: “Error: invalid building length.!” . Otherwise, calculates the building length in inches, where one yard is 3 feet, and foot is 12 inches, Sends to another file both length values: the read and the calculated as shown below. Repeats steps (1-4) until a negative value is encountered. For example, if the read values are (71 2 6), then your program must send to a new file the following: The height of a building in YD:FT:IN format = 71:2:6 The height of a building in inches = 2586

Write a program that reads a file consisting of students' test scores in the range 0-200. It should then determine the number of students has scored in each of the following ranges:0-24, 25-49, 50-74, 75-99, 100-124, 125-149, 150-174, and 175-200. Output the score ranges and the number of students. (Run your program with the following input data: 76, 89,150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129,149, 176, 200, 87, 35, 157, 189.)
Using Programming C++..... a) Write a program that reads a text file in which each line in the file consists of a first name, a last name, following by 4 grades (double types) like Tim Hanes 78.3 98.0 80.5 72.3 The program must read every line of the text file, find the average of the 4 grades then print the names followed by the averages (one name per line) in a second file as well as on the monitor. b) Create the text file with at least 5 entries with the format given in part (a). Give the absolute path of the file in your computer. Test your program in part 2(a) on this file.
Write a program that reads a student's name followed by five test scores. The program should output the student's name, the five test scores, and the average test score. Output the average test score with two decimal places. The data to be read is stored in a file called test.txt. The output should be stored in a file called testavg.txt. test.txt: A file containing the student names and the five test scores for every student.

For this program, assume you have an input file with several lines of text. Each line has a student's last name, followed by a space and then 4 numbers which represent his/her grades. Your program should read this input file and produce an output file with the same number of lines, each line showing the last name and the average of the student's scores. "grades.txt" is the file your program should read. "badformat.txt" is an example of a file that your program can't read, so a clear error message should be generated, as shown in the sample output. Your program must catch all exceptions. Your main method must NOT have a "throws" clause - it must catch all exceptions and dea' with them appropriately. Other methods may throw exceptions, as long as the main method catches them. I don't expect you to examine any filenames to make sure they're valid. Instead, you should use the filename the user gives you and try to open a file by that name. That will throw an exception if the filename is…
Write a Python program that reads from the user the name of two files (an input file and an output file). The program will then read each line of the input file and save it in the output file preceded with the line number and removing any of the following punctuations (. , ! ? ; :) found at the end of the line. For example, if the input file is:Mary had a little lamb;Whose fleece was white as snow; And everywhere that Mary went; The lamb was sure to go!Then the output file the content of the input file and saves it in the produced output file will beLine 1: Mary had a little lambLine 2: Whose fleece was white as snow Line 3: And everywhere that MaryLine 4: The lamb was sure to go
