- in c++ Write a function named createOneStudent that will read in from the user the student info: id, name and gpa. It will use try-catch to handle the exception if the user provides a negative id or gpa that is out of bound (< 0.0 or > 4.0) by asking the user to re-enter them. It must provide the correct reason for the error and the actual error value. Then it will allow the user to try up to 3 times. This function will return the pointer of a newly created Student object or nullptr if the info is still incorrect. Note that this function can and will use cin and cout to read in values from the user. Here is an example of a run up to 3 times: Enter ID: -1 Enter GPA: 4.0 Enter name: John Smith Exception: negative id: -1 Enter ID: 1234 Enter GPA: 5.0 Enter name: John Smith Exception: out of bound gpa: 5.00 Enter ID: 1234 Enter GPA: 4.0 Enter name: John Smith ID(1234) NAME(John Smith) GPA(4.00) Here is an example of a run of 3 times and still not able to create it: Enter ID: 1234…def test_func(a,b,c): return (a+b)/c This function is normally designed to be used with three numbers: a, b, and c. However, a careless coder may call this function with an ill combination of arguments to cause certain exceptions. Specifically, if any of a, b or c is not a valid number, then this code will produce a TypeError; and if a and b are valid numbers, and c is 0, then the code will produce a ZeroDivisionError. Your job is to enhance this function by adding proper try...except... blocks, surrounding and capturing the exceptions. When a TypeError occurs, instead of crashing, your code must print on the screen: "Code produced TypeError". And, when a ZeroDivisionError occurs, instead of crashing, your code must print on the screen: "Code produced ZeroDivisionError". In both cases, your function will not crash, will not throw an exception, and silently return None.Write a function average(num1, num2) that returns the average of the two numbers, (num1+num2)/2. The function prints "Non-numerical arguments" if num1, num2 are not numerical. Cannot compute the average!" in the terminal and exits without crashing the programme. This task requires Python exception handling.
- In C++, Complete the following function that takes an integer as an argument and returns a power of two greater than or equal to input. If input is less than 1, the function should return 0. Ex.) 1.) 8 => 8. 2.) 15 => 16. 3.) 17 => 32 My code: #include <bits/stdc++.h> #include <fstream> #include <iosstream> #include <sstream> #include <strings> /* complete the 'PowerOfTwoCeling */ int PowerOfTwoCeling(int a) { } int main() { std::ofstream fout(std:: getenv("OUTPUT_PATH")); std::string inputString; std::getLine(std::cin, inputString); std::stringstream input(inputString int a; input >> a; fout<< PowerOfTwoCeling(a); fout.close(); return 0; }In C++ Language (please use hint) : Write a function which will swap its arguments if the first argument is greater than its second argument, but will not interchange them if the first argument is samller than or equal to the second argument. The function should return 1 if a swap was made, and 0 otherwise. (Hint: Make sure to use call by reference.) Write also a short test driver (i.e. a main() invoking your function).Computer Science PowerShell Validate Set Parameters. Hello, I have to design a PowerShell script that uses ParameterSetNames in the function. What I am trying to achieve is I have a script Invoke-Script -year $year -duration $duration -quarter $quarter -month $month The choice in the duration part should only be Quarterly or Monthly using ValidateSet But the next step is where I am stuck, I want if the user picks Quarterly then the line should execute without the month perimeter, and vice versa if the user selects monthly then only month needs to be inputted.
- Please answer it in python Write a ReadListInteger function without arguments that reads positive or null integers entered on the keyboard. The input stops when entering a negative number. The function returns the list of integers entered. Propose a ReadListFloatBornes function with two optional arguments bmin and bmax, which allows you to read real typed on the keyboard. Typing stops when the user enters a value outside the [bmin; bmax]. By default, the values of min and max are set to 0 and 100 respectively. The function must return a list. Define an MMSList function that takes a list as an argument and returns the minimum, maximum, and sum of the list. Your function must use a while or for loop. Complete your main program using ReadListReelsBornes to enter a list of reals on the keyboard and MMSListe to get the minimum, maximum and sum of the values entered. Display the 3 values obtained in the console.Code should be in Python, please Complete the check_character() function which has 2 parameters: A string, and a specified index. The function checks the character at the specified index of the string parameter, and returns a string based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character. Ex: The function calls below with the given arguments will return the following strings: check_character('happy birthday', 2) returns "Character 'p' is a letter"check_character('happy birthday', 5) returns "Character ' ' is a white space"check_character('happy birthday 2 you', 15) returns "Character '2' is a digit"check_character('happy birthday!', 14) returns "Character '!' is unknown"I need your help with the question attached, Your writing your program in C# .

- The included attachment gives the hex2Dec(const string& hexString) function that returns a decimal number from a hex string. Implement the hex2Dec function to throw an invalid_argument exception if the string is not a hex string. Write a test program in C++ that prompts the user to enter a hex number as a string and display thenumber in decimal.In c++ Use pointer. Write a function named “hasHelpOption”that accepts argc and argv (same data typesof command line arguments), it will return true if it has the argument of “/help”or “/?”or “—help”and false otherwise.Please show how this function is being used and tested.Write a function, named randomPassword, that generates a random password that takes no parameter. It will return the randomly generated password as its ONLY result. Display the randomly generated password in the main program. Password Criteria: o The password should have a random length of between 7 and 10 characters. o Each character should be randomly selected from positions 33 to 126 from the ASCII table You must import randint function directly and inline within the random package and it must be the first line of code in your program, after your program header comment. o Declaring and using FOUR constants. Constants must be named appropriately and intuitively. o You must use the chr built-in function within your randomPassword function: o Declaring the main function and invoking randomPassword function. o Logical approach to problem solving, computation, and displaying appropriate output.
