Suppose that we want to store digitized audio information in a binary file. An audio signal typically does not change much from one sample to the next. In this case, less memory is used if we record the change in the data values instead of the actual data values.
We will use this idea in the following
Write a program StoreSignal that will read positive integers, each of which must be within 127 of the previous integer, from the keyboard (or from a text file, if you prefer). Write the first integer to a binary file. For each subsequent integer, compute the difference between it and the integer before it, cast the difference to a byte, and write the result to the binary file. When a negative integer is encountered, stop writing the file.

- Write a program to read several lines from a file. For each line, check (recursively) whether it is a palindrome. If it is a palindrome output the original string preceded by an integer (a counter) , like this: 1 : Sore was I, ere I saw Eros.2 : A man, a plan, a canal -- Panama Recall that a palindrome is a String that is the same backwards and forwards. Some examples of single words that are palindromes are: level, madam, racecar Phrases can also be palindromes if you strip out all the whitespace and punctuation and make everything the same case. Some examples are: Madam, I'm Adam A Toyota's a Toyota (See the palindrome video for more) You will need one method to eliminate whitespace and punctuation , make everything lowercase, and return the new string. Use the recursive method you wrote in L15Num2. This returns a string with no whitespace or punctuation, but not all the same case. Then (in main) convert that string to lowercase. You need a recursive method that takes the new…arrow_forwardImplement the following programs in cpp code; Write a program to convert all the characters in uppercase in a file txt. Write a program to find a string “is” from a file txt. Write a program that takes input in 100 students(id, name, age, gender) and write their data in file student.txt and find from file how many students are of age 18. Write a program that takes input in 50 employees(id, name, salary, age) and write their data in file employee.txt and find from file salary of an employee with id 13.arrow_forwardSuppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line. For example, if the input file contains Ed Marston Bob Jones Jeff Williams Fred Charles The output file should be Bob Jones Ed Marston Fred Charles Jeff Williams Use arrays to solve the problem.arrow_forward
- Write a program that generates 10 random doubles, all between 1 and 11, and writes them to a text file, one number per line. Then write another program that reads the text file and displays all the doubles and their sum accurate to two decimal places.SAMPLE OUTPUT 10.6269119604172 2.737790338909455 5.427925738865128 1.3742058065472509 1.1858700262498836 4.180391276485228 4.910969998930675 5.710858234343958 7.790857007373052 3.1806714736219543 The total is 47.13arrow_forwardYou are required to implement a program which will read in a text file (.txt) containing words which are arranged in sentences. Your program should first ask the user for the name of the file and then count the number of individual words and characters (including numbers and punctuation) in the file. The word and character count result should be printed on the screen. Furthermore, your program should count the number of individual words starting with the letter 'A', 'B', 'C' and so on to 'Z'. Again, these statistics should be printed on the screen. Your program should display the letter that appears at the start of most words. The program must be written in C. You should illustrate the operation of your program by generating a text file containing 3 sentences from a lead news story on the day of testing.arrow_forwardWrite a program that reads a file consisting of students’ test scores in the range 0–200. It should then determine the number of students having scores in each of the following ranges:0–24, 25–49, 50–74, 75–99, 100–124, 125–149, 150–174, and 175–200.Output the score ranges and the number of students. (Run your program with the following input data: 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189 #include <iostream> #include <fstream> #include <string> using namespace std; int main() { int scores; int i [8] = { 0 }; ifstream infile("Ch8_Ex4Data.txt"); if ("Ch8_Ex4Data.txt") { while (infile >> scores) { if (scores >= 0 && scores <= 24) i[0]++; if (scores >= 25 && scores <= 49) i[1]++; if (scores >= 50 && scores <= 74) i[2]++; if (scores >= 75 && scores <= 99)…arrow_forward

Write these integers into an output file (“output.txt”). You may assume the length of each integer to be a minimum of 2 digits.

Your program must contain at least the following functions: a function called GetData to read and store data into two arrays, a function called Average that is used to calculate the average test score and grade, and a function called PrintResults to output the results. The student names should be to the left with a width of 10 columns. The test scores should be to the right with a width of 8 columns.
