- The stream extraction operator >> can be overloaded with an operator function thattakes an istream reference and a reference to a user-defined type as arguments and returns an istream reference T/FThe stream insertion operator << can be overloaded with an operator function that takesan istream reference and a reference to a user-defined type as arguments and returns anistream reference. T/FThe stream insertion operator << and the stream extraction operator >> are overloadedto handle all standard data types—including strings and memory addresses (stream insertion only)—and all user-defined data types T/F
- Why are the stream Insertion (operator) and stream Extraction (operator>>) functions required to return a reference ostream and Istream, respectively?If a nonrecoverable error occurs during a stream operation, the bad member functionwill return true. T/FTHIS IS THE REFERNCE FOR COPY:Dictionarya) Define a function createUser() with an arbitrary dictionary parameter. This function returns a dictionary based upon input arguments.b) Define a function printUser() with a parameter user which is a dictionary. This function prints the contents of the dictionary user.c) Create and print the user: John, age 43, job Programmer, Hobby Bikingd) Create and print the user: Sara, age 20, school QCC, major CSIS ANSWER THIS QUESTION: Modulesa) Create a file userFunctions.py: 1. Copy nameFormat(), createUser(), and printUser() from the problems above into the userFunctions.py file. 2. Modify nameFormat() to accept only two parameters first and last. Change last to an optional parameter. This function should now return either first or last, first. 3. Define a function printUsers() which accepts a list parameter users. This function calls the printUser function to print all user data.b) Create a separate file, functionModule.py: 1. Import all functions…
- (PYTHON) a) get_total_cases() takes the a 2D-list (similar to database) and an integer x from this set {0, 1, 2} as input parameters. Here, 0 represents Case_Reported_Date, 1 represents Age_Group and 2 represents Client_Gender (these are the fields on the header row, the integer value represents the index of each of these fields on that row). This function computes the total number of reported cases for each instance of x in the text file, and it stores this information in a dictionary in this form {an_instance_of_x : total_case}. Finally, it returns the dictionary and the total number of all reported cases saved in this dictionary. (Suppose we want to know the total number of cases reported on each date, so use x = 0.) >>> result, total_cases = get_total_cases(database, 0) >>> display_dict(result) 2021-05-19: 8 2021-05-20: 2 2021-05-21: 1 2021-05-22: 1 >>> print(total_cases) 12Establish a stream insertion operator.In C++, Define struct StudentInfo; maintain records in a vector<StudentInfo>. Program prompts for and fetches data, builds vector of student records, sorts by name, calculates max and min grades (no names, just max and min numbers), class average, prints summarizing data along with class roll and grades. Test program. Note: add constructors (default/parameterized wherever applicable)

(Try to avoid linked lists if possible please). Add comments. Thanks. • Each functionality component must be implemented as a separate function, though the function does not need to be declared and defined separately • No global variables are allowed • No separate.hor.hpp are allowed • You may not use any of the hash tables, or hashing functions provided by the STL or Boost library to implement your hash table • Appropriate, informative messages must be provided for prompts and outputs You must implement a hash table using the Double Hashing collision strategy and the mid-square base 10 hashing function with an R of 2.
