a.
- Include library files for various operations.
- Declare object ofofstream.
- Create a statement to open the write data to the file “employee.dat”.
- Use if statement with fail() method to check that the entered file name is available or not.
- int main() function is used to perform all the task.
- Display the calculated results to the user.
Program Description: The main purpose of the program is to create a text file, “employee.dat” and to write the given data to the file.
b.
Program Plan:
- Include library files for various operations.
- Declare objects ofifstream and ofstream.
- Declare required variable.
- Create two statements to open “employee.dat” and “employee.bak” file.
- Use if statement with fail() method to check that the entered file name is available or not.
- int main() function is used to perform all the task.
- Display the calculated results to the user.
Program Description: The main purpose of the program is to modify the program code of part (a) so that the program code can create a duplicate copy of the text file with the name “employee.bak”, that contains all the data of “employee.dat” file.
c.

In this paper, a sign languagesentence recognition algorithm is proposed based on weighted key frames. Key frames can be regardedas the basic unit of sign word, therefore, according to the key frames we can get related vocabularies, and thus we can further organize these vocabularies into meaningful sentence.

- (DONT USE STRUCTURE... USE CLASSES) Write a C++ program which takes multiple Employees information (records) as inputs from the user and save them on a file using class. Writing in file should be done using setters. Perform following operations on the data saved in the file:• Read data from file• Search an employee’s information in the file• Count the number of employees having salary more than 50,000.arrow_forward[no. 19] When would you use a while loop? a. when you want some code to continue running as long as some condition is true b. when you want to run code in one file while code in another file is also running c. when you want to minimize the use of strings in your code d. when you need to run two or more chunks of code at once within the same filearrow_forward(Write a C++ program) This homework is from our textbook page 459 # 16. The Dodgers recently won the World Series vs the Tampa Bay Rays. Attached are two files: Teams.txt - This file contains a list of serveral Major League baseball teams in alphabetical order. Each team is listed in the file has won the World Series at least once. WorldSeries Winners.txt - This file contains a chronological list of the World Series' winning teams from 1903-2020. (The first line of 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 2020. Note the World Series was not played in 1904 or 1994.) Write a program that displays the contents of the Teams.txt file on the screen and prompts the user to enter the name of one of the teams. The program should then display the number of times that team has won the World Series in the time period from 1903 to 2020. In the program, 2 arrays are needed: TeamList array and Winners array.

- (C++ Programming) You are given a file consisting of students’ names in the following form: lastName, firstName middleName. (Note that some students may not have a middle name.) Write a program that converts each name to the following form: firstName middleName lastName. Your program must read each student’s entire name into a variable and must contain a function that takes as input a string, consisting of a student’s name, and returns a string consisting of the altered name. • Use the string function find to find the index of , • the function length to find the length of the string • the function substr to extract the firstName, middleName and lastName. Output the altered name into a file. This program has no user interface.
