Question B. Write a C++ program that reads the marks of a group of students from a text file "grades.txt" and computes the average of all grades. The program must check the file for any opening problems, and then proceeds to do the other tasks. The input file can have 1 or more students. The text file and sample-output are shown as below: O grades - Notepad File Edit Format View Help 60.0 78.6 78.0 98.6 77.7 55.0 73.0 80.7 80.0 85.0 Windows (CF Ln 13, Col 1 100% CAUsers\Imran\Desktop\Lab111\Debug\Lab111.exe Average of 10 students is 77 Press any key to continue...

Program in C only - thanks Write a C Program that writes all the numbers from 1 to 100,000 that are both prime and the sum of the digits > 9. For example 47, 911 are 2 such numbers, since the sum of the digits is > 9. After finding a number, you must immediately write it to the output file. Open the file, write the number you just found, and close the file. Measure how much elapsed time it takes to do this processing. Yes, it is inefficient, but we are trying to force some I/O usage, which will cause interrupts. When this process is completed, next have the program fork and create 10 separate processes. Each process would find search a range of 1 to 100,000 for these prime and sum 11 numbers. One process searches 1 to 10000, another 10001 to 20000 etc. Each process performs the exact same tasks , in the same way, as the first part of the problem, but write the output to 10 separate files, one for each process. When all 10 processes are done, read the ten files to make one file…
Write a complete program that reads integers from a file called numbers.txt, and displays their sum on the screen. Example: If the content of numbers.txt is: 10 20 30 100 The program should print: 160Program should be written in c++
Write a C program named toupper.c that reads the contents of a file, and writes to another file after changing all lowercase letters in the input file to uppercase. 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: ABCDEFG
Write a C program Assume that numbers.txt is a textfile with non-negative integers, with one per line, with -1 on its very last line, to indicate the end of the data. Write a segment of code that opens this file to read from, counts how many of these numbers are in between 90 and 100, inclusive, prints out this count to the screen, and closes the file.
Q2: Write a complete C++ program that reads the contents of the text file "mydata.txt", character by character. And appends them to the end of text file "myoutput.txt" . The main function calculates and prints the number of characters read and copied between the files.
You are required to write a C++ program that reads several hundreds of movie ratings from an input file, and output a list of Number of times rated (#Rated), sum of ratings (Total Ratings) and average ratings of the movies.The application program reads in several hundreds of movie ratings from an input file“Rating_list.txt”. Each line in the input file represents one review, indicating the title of the movie and a rating (between 0 and 5) separated by a space. Sample lines from the input file is shown below.

Write a C++program to read a series of product names, count, and price of each item in a file called cart.in to the end. Calculate the cost of each item and the total amount spent before taxes. Assuming the sales tax applied is 5.7%, display the total cost of each item and the total amount after taxes. Output the results to a file called receipts.out. The output must be in the form shown below. Attach the code and screenshot of a successful run on the program. ==== Your receipt Item Count Price/Item Item Total Pens 3 $ 2.99 $ 8.97 Notebook 5 $ 3.00 $15.00 Shoes 1 $ 25.19 $ 25.19 ===================== Subtotal $ 49.16 ===================== Total $ 51.96

Hi, i need help with this program using Java. Write a program that reads the file AdventuresInWonderland.txt one line at a time and prints the count of each of the five vowels followed by a count of the consonants in the file. Coding requirements: Read the text from the file AdventuresInWonderland.txt. Use a single while loop to read the lines of the file. Use a single for loop to iterate over the characters in each line. Use a single switch statement to determine which counter to increment. Notes: The input may contain punctuation and digits as well as letters. Account for both uppercase and lowercase letters. Character.toLowerCase(ch) returns the lowercase character corresponding to ch(char ch). Character.toUpperCase(ch) returns the uppercase character corresponding to ch(char ch). Character.isLetter(ch) returns true when ch is an alphabetic letter Expected output: Vowels found: a: 324 e: 455 i: 251 o: 300 u: 109 Consonants: 2384 Example: If one creates a Scanner as…
The course records are shown below: Each student has 4 assignments. 108194 9 10 10 10 197526 10 10 10 10 197008 10 10 0 10 197746 10 10 9 10 108154 10 0 10 9 Create an input file ‘CSassignments.txt’ using an editor such as Notepad++ with a student number, then a space, then four assignment marks on one line. The assignment marks are whole numbers and are separated by a space. Your C++ program will read from the file ‘CSassignments.txt’ and write to a second file ‘CSgrades.txt’ which includes the average of the student’s four assignments. e.g. 108194 9 10 10 10 9.75 Your C++ program should work with any number of records in the ‘CSassignments.txt’ input file – that is – test your program with TWO records…
