Question
I need to write a C++ program that will read in a two dimensional array from a file after prompting for the file from the user. The first two values in the file are the dimensions of the array. The dimensions will NOT exceed a 20 by 20 2d array and are guaranteed to be at least 0 by 0. The rest of the values will be integers delimited by white space. Determine the largest and smallest values in the file.
Program Requirements:
- Use global constants for the maximum dimensions of the array
- Use a void function called FillArray that accepts four arguments (an input file object, a two dimensional array, the actual row size, and the actual column size). This function should read through the file and fill the array. The file object, row size, and column size should be defined as reference parameters.
- Use a value returning function called FindMax that accepts three arguments: the 2d array as a constant parameter, the row size, and the column size. It should return the largest value in the array.
- Use a value returning function called FindMin that accepts three arguments: the 2d array as a constant parameter, the row size, and the column size. It should return the smallest value in the array.

Enter filename to process: nofile.dat
nofile.dat not found!
2. Sample Run 2 (dataone.dat)

Max value: 7
3. Sample Run 3 (datatwo.dat)
Enter filename to process: datatwo.dat
Min value: -99
Max value: 100
4. Sample Run 4 (datathree.dat)
Enter filename to process: datathree.dat

- Topical Information Use C++. This lab should provide you with practice in file handling, libraries, and random variate generation. Program Information Write a program that allows the user to create files of random data. They should be offered a menu of possibilities: 1) create random Whole number data file 2) create random Decimal number data file 3) create random Character data file 4) Quit program The first 3 options should ask for appropriate bounds. Your program should make sure they are in order before passing them to your random value generation function. Then, ask how many random values to generate and what file to place them in. Assuming the file opened correctly, proceed to generate all requested random values. The menu should continue to loop until the quit option is chosen. Options should be choosable by either the number or the capitalized word. (For example, to quit, they should be able to enter 4, Q, or q.)arrow_forwardHow do I do this C programming question?arrow_forward59. Question: Write a C++ program. Using Dynamic Array, read a data file containing some names into a dynamically declared array. Note that the total number of names is not known so your program should determine it. Create a second array that contains the names in alphabetical order. Produce an output file containing the alphabetized list. Important: Do not copy codes from prepinsta.com.arrow_forward

Output the resulting matrix in proper format. SPECIFICATIONS that you need to follow: - The maximum size of the square matrices is 10x10. Matrices 1 and 2 should have the same dimensions. - You may only use the codes that we studied under our lectures - All lines of codes should have a comment. - Save your cpp file as Surname_FE (Example: Pangaliman_FE.cpp) TEST CASES: If a user inputs n = 2: Input: Input dimension (nxn) of the matrix, n = 2Input Matrix 1 elements: 1 2 3 4Input Matrix 2 elements: 5 6 7 8 Result: Resultant matrix: 19 22 43 50 If a user inputs n = 10: Input: Input dimension (nxn) of the matrix, n = 10 Input Matrix 1 elements: -35 54 64 31 45 -12 17 -31 -19 -78 -35 54 3 -10 -11 90 -41 31 -30 0 22 -53 21 -13 -64 32 -70 57 58 86 -77 30 73 24 -77 -90 -26 85 48 -47 -96 58 70 -59 82 -97 43 51 45 62 63 40 67 42 52 -78 -69…arrow_forwardUSING PYTHON: Create a function that takes a filename("string") of a PGM image file as input and loads in the image in the file, and returns it as an image matrix.
