1. Write a program that asks the user for the name of a file. The program should display only the 3 lines of the file's contents. If the file contains less than 3 lines, it should display the file's entire contents. Use the file: lorem_ipsum.txt to test your program. Comment your source code and describe your code to someone who may be viewing it for the first time. PLACE SCREENSHOTS OF THE PYTHON CODE AND ALL I/O BELOW. Please use Python Programming
Write a program which reads the first two characters from the file “chars.txt” and writes thesum of their ASCII code values as a number into “codesum.txt”. Use an editor to create theinput file “chars.txt”. Your program is responsible to create the output file “codesum.txt”.You can safely assume that the content of the input file will be valid.(Please write in C programming language).
Chapter 4. PC #6. File Letter Counter (page 264) Write a program that asks the user to enter the name of a file, and then asks the user to enter a character. The program should count and display the number of times that the specified character appears in the file. Class name: FileLetterCounter Hints: Hint 1. To read a single character from the keyboard, you need to read a full line and then take the first character in position 0. Hint 2. To count the occurrences of a given characters in a file you need to read the file line-by-line using a while loop, then for each line check all characters in all positions and increment the character counter for each occurrence. This will require to have a for-loop nested inside the while-loop.

D) Create a program that will read a text file with the answers to 10 multiple-choice questions and compare them to the correct answers stored in a tuple. correct answers: 'A','B','C','D','D','C','B','A','A','C' After the answers have been read from the file, the program should display a message indicating whether the answer stored on the file was correct or not. If the answer was was incorrect, display the correct answer. The program should display the total number of correct and incorrect answers, followed by a message of "Good job!" if the file has 8 or more correct answers. PYTHON
This class prints the first several lines of a file. The default is to print 5 lines, but the -n flag can specify a different number. If no file is specified on the command line, read from standard input. The code bekoow is to help get started. #include <stdio.h> #include <stdlib.h> // You may assume that lines are no longer than 1024 bytes #define LINELEN 1024 static void usage (void); int main (int argc, char *argv[]) { return EXIT_SUCCESS; } static void usage (void) { printf ("head, prints the first few lines of a file\n"); printf ("usage: head [FLAG] FILE\n"); printf ("FLAG can be:\n"); printf (" -n N show the first N lines (default 5)\n"); printf ("If no FILE specified, read from STDIN\n"); }
Python Code: Below is an open link to file needed in this program Spots: https://drive.google.com/file/d/1uaqwxYYn4AHJlFB0ukxm3PD8ISoakz6F/view?usp=sharing libraries numpy as np and matplotlib.pyplot as plt must be imported and then used. Write a program which reads the data from the file spots.txt (linked above), and then calculates the mean, median, mode and standard deviation of the data. Using the above information, the program should then plot a histogram of the number of sunspots/month distributed over 50 bins. Use the plt.hist() function to help you with this.
