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.

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.
my_list.txt: 150+250 Which of the following code blocks writes the sum (400) in a new line of the file? a. with open('my_list.txt', 'r+') as file: line = file.readline() sum = 0 for i in line.split('+'): sum = sum + i file.write(str(sum)) b. with open('my_list.txt', 'r+') as file: line = file.readline() for i in line.split('+'): sum = sum + int(i) file.write(str(sum)) c. with open('my_list.txt', 'r+') as file: line = file.readline() sum = 0 for i in line.split(): sum = sum + int(i) file.write(str(sum)) d. with open('my_list.txt', 'r+') as file: line = file.readline() sum = 0 for i in line.split('+'): sum = sum + int(i) file.write(str(sum))
Question 2: Write a program that reads words from a text file and displays all the words (duplicates allowed)in descending alphabetical order. The words must start with a letter. The text file is passed as acommand-line argument.
A file contains only spaces, commas, colons, digits, and newlines in the following frequencies: colon (100), space (605), newline (100), comma (705), 0 (431), 1 (242), 2 (176), 3 (59), 4 (185), 5 (250), 6 (174), 7 (199), 8 (205), 9 (217). Construct Huffman code.
C++ Add a search command that asks the user for a string and finds the first line that contains that string. The search starts at the first line currently displayed and stops at the end of the file. If the string is found, the line that contains it is displayed at the top. In case the user enters a string X that does not occur in the file, the program should print the error message: ERROR: string "X" was not found.
This is the statement it gives - Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. Assume also the last names and first names do not contain whitespaces. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam. Output the last names, first names, exam scores,…
