C++ Lexicographical Sorting
Given a file of unsorted words with mixed case: read the entries in the file and sort those words lexicographically. The program should then prompt the user for an index, and display the word at that index. Since you must store the entire list in an array, you will need to know the length. The "List of 1000 Mixed Case Words" contains 1000 words.
You are guaranteed that the words in the array are unique, so you don't have to worry about the order of, say, "bat" and "Bat."
For example, if the array contains ten words and the contents are
cat Rat bat Mat SAT Vat Hat pat TAT eat
after sorting, the word at index 6 is Rat
You are encouraged to use this data to test your program.
TRUE OR FALSE
You should not pass a one-dimensional array to a function.
Passing an array by reference is more efficient than passing it by value.
The quick sort algorithm provides a quick and easy way to sort the items stored in an array, as long as the number of items is relatively small—for example, fewer than 50.
The variables in an array may be stored in non-consecutive memory locations in the computer’s internal memory.
It takes longer for the computer to access the information stored in a disk file, than in an array in memory.
kindly write a complete program that opens the file, sheet.txt (I will type the data that is in this file) for reading. The open operation on the file must be verified and if the file did not open, the program should exit after printing an error. The file contains a single column of double numbers that must be read into an array. The file contains no more than 100 values. The file should be read until end of file. The average value should be calculated and written out to the display.
The following is an example of how it should run.
dj@schroeder: ./a.out
Average is 446.369

the following are what is in the file sheet.txt…

- (File creation) Write a C++ program that creates an array containing the integer numbers 60, 40, 80, 90, 120, 150, 130, 160, 170, and 200. Your program should then write the data in the array to a text file. (Alternatively, you can create the file with a text editor.)arrow_forward(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.arrow_forward(Statistics) Write a program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main().arrow_forward
- Part II: Image Representation An image is an array, or a matrix, of pixels (picture elements) arranged in columns and rows. RGB is one of the models used in color pixels. In a color image, each RGB pixel is an integer number which contains the mixture of red, green and blue colors. In this assignment, you will be provided with an image data file, image.dat. The first line in data file contains the height (rows) and width (columns) of the image. The following lines gives the red, green and blue color integer values for each pixel. The following sample.dat is given as an example: (The given example can be seen on the picture down) According to this input file, the image has 4 rows and 2 columns. The pixel at [0][0] has red value 117, green value 117 and blue value 245. Write a Java program that reads from the given input file and creates an RGB image object with the given width and height. Then, it'll read red, green and blue color values for each pixel from data file, and calculate RGB…arrow_forwardThis program has two filesqty and amtqty has 10 integersamt has 10 doubles read files, store values in arrays named qtyarray and amtarraycompute the product of each element:prodElement = qtyarray0 x amtarray0...display each prodElementarrow_forwardUse C++ This program will read the contents of a file into an array and calculate various values based on the contents of the file. The program will make use of a two dimensional array that has 30 rows and 5 columns. You will be reading in the contents from a file. You will need to read the file name from cin. You will prompt for the file name with the prompt: Enter input file name The file will consist of up to 30 sets of 5 values. The values will all be double floating point values. readFile function One function you will be required to have is called readFile. This function will read the input file. Each read will read in 5 columns of information into the next available row in the two dimensional array. The first 5 values are read into row 0, the next 5 values will be read into row 1, and so on up to 30 rows of input. You will need to keep track of how many rows of input you have read in. This could be anywhere from 0 to 30. If there are more than 30 rows of input you should only…arrow_forward
- NB: Square bracket notation for array access is NOT allowed for Question 3, i.e. array[i]. Array access MUST be facilitated by the use of pointers. Write a function, ReadFile(), that reads the content of the provided text file “Message.txt” and stores it in an array. The function receives as parameter a pointer to a character array where the content of the text file should be stored.. The number of lines that was read from the text file must be returned to the calling statement. Write a function, ReverseMyString(), that converts the character array (which now contains the contents of the text file) by replacing the first character with the last character, the second character replaced with the second last character, etc, until the message is reversed as shown in the Figure 3. The function receives as parameters, a pointer to the character array and an integer value indicating the length of the array. The function returns a 1 or 0 to indicate success and failure respectively. NB: You…arrow_forward1: Create a file named dedup.js. Write a program that removes duplicates from an array.

The program should first read an integer for the size of the array and then should create the two arrays dynamically (using new) and should read the numbers into array1 and array2 and then should find the common members and show it. Note: The list of the common members should be unique. That is no member should be listed more than once. Tip: A simple for loop is needed on one of the arrays (like array1) and one inner for loop for on array2. Then for each member of array1, if we find any matching member in array2, we record it. Sample run: Enter the number of elements of array 1: 7 Enter the elements of array 1: 10 12 13 10 14 15 12 Enter the number of elements of array 2: 5 Enter the elements of array 2: 17 12 10 19 12 The common members of array1 and array2 are: 12 10arrow_forward
