3.   Write a program that asks the user for the name of a file. The program should display the contents of the file with each line preceded with a line number followed by a colon. The line numbering should start at 1. Use the numbers.txt file to test your program.   (Hint: Open the file and read every string stored in it. Use a variable to keep a count of the number of lines that are read from the file.)    Comment your source code and describe your code to someone who may be viewing it for the first time.      PLACE SCREEN SHOTS OF THE PYTHON CODE AND ALL I/O BELOW. Please use Python Programming

QI: Write a program to calculate the average of four integer score, and find the grade for 7 students. The program should do the following: 1. Read the first, second name and the four score of the 7 student from the file (E:lexam.txt), 2. Calculate the average and find the grade of the average by using the if and if else. 3. Save the first, second name, average and the grade for each student in file (E:grade.txt). (10 columns for the first and second name. 4 columns, precision 2, for the average and grade)

What should the processor do if a cache request can't be completed while a block is being written back into main memory from the write buffer?

This list attached below is a chronological list of the World Series winning teams from 1903 through 2009. (The first line in the file is the name of the team that won in 1903, and the last line is the name of the team that won in 2009. Note the World Series was not played in 1904 or 1994.) Write a python program that lets the user enter the name of a team, then displays the number of times that team has won the World Series in the time period from 1903 through 2009.   Boston Americans New York Giants Chicago White Sox Chicago Cubs Chicago Cubs Pittsburgh Pirates Philadelphia Athletics Philadelphia Athletics Boston Red Sox Philadelphia Athletics Boston Braves Boston Red Sox Boston Red Sox Chicago White Sox Boston Red Sox Cincinnati Reds Cleveland Indians New York Giants New York Giants New York Yankees Washington Senators Pittsburgh Pirates St. Louis Cardinals New York Yankees New York Yankees Philadelphia Athletics Philadelphia Athletics St. Louis Cardinals New York Yankees New York…

In Python, Write a program that prompts the user for a file name. (Use problem 2.txt file) Each line of the file should be preceded by a line number followed by a colon in the program. The numbering of lines should begin at number 1. BE SURE THERE ARE NO EXTRA SPACE BETWEEN THE LINES. problem 2.txt file contents: Python language is incredibly easy to use and learn for new beginners and newcomers. The python language is one of the most accessible programming languages available because it has simplified syntax and not complicated, which gives more emphasis on natural language. Due to its ease of learning and usage, python codes can be easily written and executed much faster than other programming languages. Sample output: Answer Enter a file name: Problem 2.txt line 1 Python language is incredibly easy to use and learn line 2 for new beginners and newcomers. The python language line 3  is one of the most accessible programming languages line 4  available because it has…

Can you help me write the following C++ program:  Add a search command to the file viewer created. Thiscommand asks the user for a string and finds the first line that containsthat string. The search starts at the first line that is currently displayedand stops at the end of the file. If the string is found, then the file willbe scrolled down so that when it is redisplayed, the line that contains thestring is the first line at the top of the window.If the string is not found, the program prints the following error messageat the top of the screen:ERROR: string X was not foundwhere X is replaced by the string entered by the user. In that case, theprogram redisplays the lines that the user was viewing before the searchcommand was executed.Modify the program as little as possible. Make sure you assign new responsibilities to the most appropriate components. Use the C++ string operation find.   The file viewer code is given below: // FileViewer.cpp #include "FileViewer.h" using namespace…

In the last two exercises, you counted words and lines. The wc program counts both, as well as the number of characters in the file. To count the characters & lines, you'll need to use line oriented input and then use the line size (+1) for the character count. For the words, you'll need to use a string stream to count the words in each line. $ wc a.txt b.txt c.txt #lines, words, characters a.txt 5 32 182 b.txt 10 151 587 c.txt does not exist wc.cpp 1 #include #include #include 2 3 4 using namespace std; 5 int main(int argc, char* argv[]) { 6 7 8 9. 10 11 a1.txt Alice was beginning to get very tired of sitting by her sister on the 2 bank, and of having nothing to do: once or twice she had peeped into the 3 1. book her sister was reading, but it had no pictures or conversations in a2.txt OUT OF ITS WAISTCOAT-POCKET, and looked at it, and then hurried on, Alice started to her feet, for it flashed across her mind that she had never before seen a rabbit with either a waistcoat-pocket,…
