Concept explainers

Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

Question

Write a C program that reads real numbers from a data file named "numbers.txt", one-by-one.

For each number, the program checks whether the number is positive or negative, and writes only the positive numbers to a text file named "result.txt".

The program must use the necessary code to handle File not found/not created errors.

For each number, the program checks whether the number is positive or negative, and writes only the positive numbers to a text file named "result.txt". The program must use the necessary code to handle File not found/not created errors. Below are examples of the input and output files
Write a C++ program that opens three files (i.e. s1.txt, s2.txt, and s3.txt) and reads the data of three students. Each file contains the student first name and last name separated by a space and the student grades in three subjects as double floating-point numbers on the next line. The program should output the data in table format such that the data of each student is displayed on one line. The data of the students is ordered in the table alphabatically according to their names. The last column in the table contains the average grade of each student. The last row in the table contains the maximum grade in each subject. Notice that the width of the first column in the table is 20 and its is aligned to the left. All remaining columns have width of 7 and their data is aligned to the right. Also Notice, that all the numbers in the table must be displayed with exactly two decimal digits. IMPORTANT NOTES . Do not add any cout statements except for the final outputs as shown in the sample…
Write a C++ program that prompts the user to enter a file name that contains the scores of students in a quiz. Each line in the input file contains a student name followed by the student’s score (as shown in the sample file to the right). The program should then find out the students with the minimum score and the maximum score and display their names and scores. Marks.txt Ahmed 90 Badria 85 Noor 91 Khalid 70 Said 65 Suha 80
Write a C program that reads a text file "My_book.txt" and counts the number of characters, words, and lines in the file. Then, the program should write these counts to a new file "My_book_info.txt" in the following format: Number of characters: [count] Number of words: [count] Number of lines: [count]
In C write a program that takes a file name and two strings as command line arguments, and writes the longer of the two strings to the file with the given name. If the given strings are the same length, write the first string given to the file. If the user does not provide the correct number of command line arguments, print an error message and exit the program with a non-zero exit code.
Write a program in C++ that will let the user create a text file name NameRecord.txt and allow the user to input 5 name and 5 age in the file. The program will display the names listed in a file having the age correspond to the input of the user. Example. Enter name and age: Kim 25 Enter name and age: Jose 27 Enter name and age: John 25 Enter name and age: Anna 35 Enter name and age: Luis 29 Enter age to search: 25 OUTPUT: The following have age 25 Kim John *Using Iostream * With Screenshot
Write a C++ program that asks the user for a file name and a word for which to search. The program should search the file for every occurrence of the word. When the word is found, the line it contains should be displayed. After all of the occurrences have been found, the program should display the number of times the word was found in the file.
Write a program in C++ that creates a file. Write this data into that file column wise as a header. Then keep adding data in colum wise format. The program should check if there is data in the file and then write the data in the next row. First add: TIME DAY MONTH YEAR Then check the file and add: 01:25 07 JUNE 2008 Then check again the file and add this in next row: 14:00 30 MARCH 2019
Write a C++ program which takes 5 students’ information (records) as inputs from the user and save them on a file. you are required to take three inputs from the user: student name (string type), student age (int type) and student registration no(string type). After reading these data-items write to the file named “student.txt”. Please note: write data using append mode otherwise previous information will be lost.
Write a C++ program that reads sales data from a file called sales.txt. Each line of the file contains four data items:1. A product number which is an integer2. A product name which is a string no longer than 12 characters and which does not contain spaces3. A unit price which is a double4. A number of units sold which is an integerThe program will output the two products which generated the highest total revenue (unit price * number sold).Your program must:1. Read each line of the file storing the four items into the members of adynamically allocated structure.2. Store pointers to the structures in an array.3. Sort the array of pointers by total revenue4. Display the product name and total revenue of the top two products5.

in C#: Given a text file, write a program (console application) that counts the number of words that end with the letter "t" or "e" (not case sensitive). We’ll say that a "t" or "e" is at the end of a word if there is not an alphabetic letter immediately following it. The program should output the resulting count.
