- Please help with my C++Specifications • For the view and delete commands, display an error message if the user enters an invalid contact number. • Define a structure to store the data for each contact. • When you start the program, it should read the contacts from the tab-delimited text file and store them in a vector of contact objects. •When reading data from the text file, you can read all text up to the next tab by adding a tab character ('\t') as the third argument of the getline() function. •When you add or delete a contact, the change should be saved to the text file immediately. That way, no changes are lost, even if the program crashes laterC++ Code dynamicarray.h and dynamicarray.cppFind a line with an error in the following code segment: 1: void displayFile(fstream file) {2: string line;3: while (file >> line) 4: cout << line << endl;5: } Group of answer choices 1 2 3 4
- C++ in MS Visual Studio, continues to receive error code E0276 (identifier is undefined) in both header and CPP files. This is new to me but please help. I do use code "using namespace std; I included the header file the identifier is defined in (code - #include "degree.h") , but the compiler doesn't really connect it and wants me to include ..//degree.hFilename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list: [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as: ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”.

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 2019Create a C++ program containing a deque container that possesses the unique property of expanding at both its front and back ends. Initially, the deque holds the elements (2, 3, 4). Modify the program to include values 1 and 5, inserting 1 at the front and 5 at the back. Consequently, when the program is executed, the deque container should exhibit the values (1, 2, 3, 4, 5).
- In Java, which data type is used to store the following symbol '<' ?Suppose a csv file contains three comma-separated values (strings) on each line (see the leftcolumn of the example table below). Assume, each line of values are, respectively, thewidth, height, and depth of a box. Write a program called box.py and add thefollowing functions to this program.• read_file() takes a csv filename as a parameter that contains the widths, heights, anddepths of all boxes. This function must read the content of the file, store these values ina 2-D list as shown in the right column of the example table below, and return this list.All strings must be converted to integers before they are stored in the list. Example:csv data 2-D list[[15, 6, 3],[3, 7, 4],[6, 9, 3],[15, 6, 11],[6, 5, 5],[13, 10, 9],[9, 10, 3],[14, 5, 4],[4, 6, 11],[12, 10, 9]]• Add another function called max_volume() to this program that takes this 2-D list as aninput parameter. Each item in that list contains 3 integers representing the dimensions ofa box (i.e., width, height, depth). This…Write a C++ Program using classes, functions (recursive and otherwise), arrays and other C++ commands to sort a file using Selection Sort. The user will enter the filename.
