Part 3 Write a function that will receive the pointer of the first element of an array, as well as the number of elements in the array. The function should display the birth date of each person. Assume valid years are from 1921-2020. Tip: The underscore character serves as the first locator character for each ID number you can use this as a landmark to identify the indexes of each ID number
C++ Progrmaing Instructions Redo Programming Exercise 6 of Chapter 8 using dynamic arrays. The instructions have been posted for your convenience. The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form: TFFTFFTTTTFFTFTFTFTT Every other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry: ABC54301 TFTFTFTT TFTFTFFTTFT indicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9 (note the empty space). The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the student’s ID,…

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…
Programming language: C/C++, Java, Python, or any other advanced programming languages Project Description: the file “IntegerArray.txt” included in this project folder contains all the 100,000 integers between 1 and 100,000 (inclusive) in some order, with no integer repeated. Your task is to compute the number of inversions in the file given, where the i-th row of the file indicates the i-th entry of an array. Because of the large size of this array, you should implement a divide-and-conquer algorithm.

JAVA PROGRAM Chapter 7. PC #16. 2D Array Operations with Additional Requirements Write a program that creates an ArrayList of ArrayList of Doubles. The program should ask the user to enter the filename from the keyboard and validate the file for existence. Once the file is verified, the program should load the two-dimensional ArrayList with test data from the file. Be careful, as some of the files will contain rows with different number of elements. The program should work regardless whether the input data is perfectly rectangular or ragged. The program should have the following methods: • main. Main entry point for the program. • getRowSubtotal. This method should accept a two-dimensional ArrayList as its first argument and an integer as its second argument. The second argument should be the index of the row in the ArrayList. The method should return the subtotal of the values in the specified row. • getColSubtotal. This method should accept a two-dimensional ArrayList as…
