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...

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.
Use the following code to allow an output to the screen to play a word descrambling game in C++ #include <bits/stdc++.h>using namespace std; // Function that sorts the given string// and transform a sorted string to uppercasestring sortString(string word){ // Transformed to uppercase transform(word.begin(), word.end(), word.begin(), ::toupper); // Sort the words sort(word.begin(), word.end()); return word;} // Function that finds the anagram of// given string in the given text filevoid jumbledString(string jumble){ // Initialize strings string checkPerWord = ""; string userEnteredAfterSorting; // Sort the string userEnteredAfterSorting = sortString(jumble); // Using filehandling ifstream // to read the file ifstream words("words.txt"); // If file exist if (words) { // Check each and every word // of words.txt(dictionary) while (getline(words, checkPerWord)) { string Ch…
I need psudocode for this - Develop a simple spell checker and word suggestion program using Hashing. A dictionary of words should be given as a first argument (filename) in the program. This input file is the simple text file "Dictionary.txt", where each line is a word (see Files section). The program must ask the user to give a word. (case 1) The program must respond with “True” if the word exists in the dictionary, and must suggest words (from Dictionary) starting with the same first two letters. At the end of each suggestion the exec. time (in micro-sec) must be displayed (see "TimeInterval.h" in Files section). (case 2) If the input word does not exist in Dictionary due to user misspelling, and considering the first letter is correct, the program should return a recommended word from the dictionary (only one word). For example, instead of the word sentence, the user enters snetence, setnence, sentens, orsetence, etc; the program should return: "do you mean sentence?" If "no",…

Modify the following program to read dictionary items from a file and write the inverted dictionary to a file: characters = {'Bugs':['Rabbit', 1940, 'boy'], 'Garfield': ['Cat', 1978, 'boy'], 'Tweety': ['Bird', 1942, 'girl'], 'Sandy': ['Squirrel', 1999, 'female']} print("Printing the original dictionary") print(characters) print("") def invert_dict(characters): inverse = dict() for key in characters: val = characters[key] for list_item in val: if list_item not in inverse: inverse[list_item] = [key] else: inverse[list_item].append(key) return inverse my_invert = invert_dict(characters) print("Printing the inverted dictionary") print(my_invert) Include the following: 1) The input file for your original dictionary (with at least six items).2) The Python program to read from a file, invert the dictionary, and write to a different file.3) The output file for your inverted dictionary.…
c language, how to modify this code to add word count before and after the word removal. Thanks! the output picture is what the output should look like except the output does not work for word removal but the code below can only do word removal but not the word count. please help. #include <stdio.h>#include <string.h> void removeSubstr(char *string, char *sub){ char *match; int len = strlen(sub); while ((match = strstr(string, sub))){ *match = '\0'; strcat(string, match+len); }} int main(){ char string[100], word[100]; printf ("Enter the string: "); //user input a sentence fgets(string,100,stdin); printf ("Enter the word to be removed: "); //inputs the words to be removed gets(word); printf("The words after removing: "); removeSubstr(string, word); puts(string); return 0;}
Task 2 Get Binary 1: Implement the get_bin_1 function as directed in the comment above the function. If the directions are unclear, run the code, and look at the expected answer for a few inputs. In order to be able to compare your solution to the answer, you cannot simply print out the binary directly to the console. Instead, you have been provided with a very rudimentary stringbuilder implementation that allows you to build a string one character at a time, without the ability to erase. There are comments at the top of the code explaining how to use the stringbuilder, however you could also see how it is being used in task_2_check. Note: if you create a stringbuilder and append ‘a’, ‘b’, then ‘c’, the resulting string will be “abc” when printed. You are free to read through the stringbuilder implementation, but it is quite complicated in order to make it easy to use. As specified in the comment, you may not use division (/) or mod (%) to implement this function (as the check…
This is Python - Chapter 9 with pseudocode Write a program that uses a dictionary to record five courses and their current grades. Start with an empty dictionary and then use a loop and keyboard input to specify the course names as keys and numeric grades as values. After all five courses have been entered, use another loop and the items() method to display the course names and grades in a table, nicely formatted as you see fit with an f-string. This second loop should also determine the course name and grade of the course with the lowest grade. Report this course name and grade when the loop ends and then delete (drop) that course from the dictionary. If math is one of the courses, add 3 points to the math grade. Otherwise, report that math is not in the dictionary. In one final loop that doesn't use the items() method, display the updated courses and grades again in a table. This final loop should also determine the total of all grades so the term average accurate to one decimal…
8.In this exercise you will create a program that will be used in a digital library to format and sort journal entries based on the authors last name. Each entry has room to store only the last name of the author. Begin by removing the first name "Isaac" from the string variable journal_entry_1 by using the string function erase. Do not forget to also remove the whitespace so that the string variable journal_entry_1 will then contain the string "Newton" with no whitespaces. The journal entries should be sorted alphabetically based on the authors last name. For example, the last name "Brown" should come before the last name "Davis" Create an if statement so that if the last name contained within journal_entry_2 is alphabetically less than the last name contained within journal_entry_1, then the string values are swapped using the string function swap. You may use either of the comparison operators < > in the if statement but remember that following ASCII, "A" is lexicographically…
A Canadian postal code is a six-character alphanumeric string that represents a part of a postal address. They are in the format of A1A 1A1, where A could be any letter and 1 could be any number from 0-9. Given an unsorted list of postal codes, write a Python program, in a file call postal.py, to sort the list of postal codes (actually modify the given list into a sorted list) and then display the sorted postal codes such that each postal code with the same starting letter is printed on the same line, with each line in alphabetical order. Note that the postal codes can be in any order on the same line, as long as they all start with the same letter, or you can have them sorted on the line as well. For example, given the following list of postal codes: postal_codes = ['A1A 1A1', 'B3K 5X5', 'V9A 7N2', 'A0Z 6P7', 'H0H 0H0', 'A1B 1T0'] The output would be similar to: Sorted postal codes: A0Z 6P7 A1A 1A1 A1B 1T0 B3K 5X5 H0H 0H0 V9A 7N2 Note: You are not permitted to use the sort() method.
