S. Malik In C++ In this programming exercise, you use abstract classes and pure virtual functions to design classes to manipulate various types of accounts. For simplicity, assume that the bank offers three types of accounts: savings, checking, and certificate of deposit, as described next. Savings accounts: Suppose that the bank offers two types of savings accounts: one that has no minimum balance and a lower interest rate and another that requires a minimum balance and has a higher interest rate. Checking accounts: Suppose that the bank offers three types of checking accounts: one with a monthly service charge, limited check writing, no minimum balance, and no interest; another with no monthly service charge, a minimum balance requirement, unlimited check writing, and lower interest; and a third with no monthly service charge, a higher minimum requirement, a higher interest rate, and unlimited check…Book : Peter Sestof - Programming Language Concept Page: 158 pdf Exercise 8.9 Extend the language and compiler to accept initialized declarations such as int i = j + 32; Doing this for local variables (inside functions) should not be too hard. For global ones it requires more changes.
- Topic: A function with parameters passed by value and passed by reference Do not use anything beyond Chapter 6 materials. Write a C++ Write a single function rectangleAreaPerim (width, height, area, perimeter) that calculates both the area and the perimeter of a rectangle given its width and height. -Input parameters to the functions are the width and height of the rectangle. Function cannot modify the input parameters. -Output parameters of the function are the area, perimeter, and a boolean return (success or failure). -This function returns true if both width and height are not negative, and thus calculation is required. Otherwise the function returns false and skips all calculations. -The function rectangleAreaPerim(width, height, area, perimeter) should Not use any "cin" or "cout". Only the main() function will contain "cin" and "cout". -The main() function calls the function rectangleAreaPerim() in a loop until the user enters 0 0. These are "Sentinel" values that stop the…1. Code question First, answer this code question: This is a javascript function. Please input the response of this function in the field below. function test(name, birth_year, current_year) { const age = current_year - birth_year; const response = name + " is " + age; return response;}test("alice", 1823, 1902) Enter the return value of the function.language: atom code only, no other software (please read) Write a function definition to return the first index of a character in a string.1. Accept the string and a character as parameters.2. Return the first index of the character in the string or -1 if the character does not exist in the string. Example 1Given the string borough and the character o return the index 1.Example 2Given the string new york and the character z return the index -1. language: atom code only, no other software (please read)
- 2.15 The principle of locality maintains that variable declarations should come as close as possible to their use in a program. What language design features promote or discourage this principle? How well do Python, C, C++, and Java promote this principle?Describe how memory allocation is done to objects and also develop a C++ programfor employee class with following attributes such as Employee ID, Employee Name,Designation and Salary. Program should sort and display the list of employees inascending order of their salaries using object as a function argument. (Note:Employee ID must not be inputted by the user i.e., auto incremented.)Programming - C Language Find the code of the following: 1. FORGIVEN!! Yeeey!! Thanks to your help, my friend Lionel Richie forgave me! In return to his kindness and compassion, I want to give him a gift. I'm thinking of giving him straight up cash! I've already prepared something in advance, I just need your help to complete it. Instructions: In the code editor, you are provided with a main() function that asks for an integer input from the user which represents the cash to be given to Lionel and passes it to the getGift() function call. The getGift() function is already declared and partially defined. Your task is to complete the function definition. The getGift() function multiplies the passed integer value by 3 and then checks if the result is even. If it is, the getGift() function adds 100 to the result. Otherwise, it adds 200 to the result. The getGift() function would then return the result as the return type of this function is int. Input 1. Cash amount…
- 2.18 Most programming languages now use the free format pioneered by Algol60, in which state- ments can begin anywhere, but must end, not with the end of a line of text, but with an explicit end symbol, such as a semicolon. By contrast, Python and a few other languages use fixed format, in which statements begin in a particular column and end at the end of the line of code, unless continuation marks are provided. Discuss the effect of fixed or free format on readability, writability, and security.This exercise assesses the skills required to develop user defined functions, and pointers. Exercise 2Write a C++ program to develop a Vehicle Fine Management System for Police. The program will have the following features.1. A user defined function called “Student Registration”. This function prompts a user to enter a student’s personal data i.e., Student Number, Student Name, Age and City and stores them. 2. A user defined function called “Module Enrolment”. This function takes student number from themain function as an argument and prompts a user to enter student two modules details i.e. Module name, Module Code and Module Credits Hours (15 or 30) and stores them. The programs should display an error message if a user enters credit hour other than 15 or 30. 3. A user defined function called “Student Assessment”. This function takes student number from the main function as an argument and prompts a user to enter Module 1 and Module 2 marks and storesthem. 4. A user defined function…Write these codes in c language please. Thank you in advance 1. Define a function PrintFeetInchShort(), with int parameters numFeet and numInches, that prints using ' and " shorthand. End with a newline. Remember that "\n" in a string literal starts a new line. Ex: PrintFeetInchShort(5, 8) prints:5' 8" 2. Write a function so that the main() code below can be replaced by the simpler code that calls function MphAndMinutesToMiles(). Original main(): int main(void) { double milesPerHour; double minutesTraveled; double hoursTraveled; double milesTraveled; scanf("%lf", &milesPerHour); scanf("%lf", &minutesTraveled); hoursTraveled = minutesTraveled / 60.0; milesTraveled = hoursTraveled * milesPerHour; printf("Miles: %lf\n", milesTraveled); return 0; } 3. Define stubs for the functions called by the below main(). Each stub should print "FIXME: Finish FunctionName()" followed by a newline, and should return -1. Example output:FIXME: Finish GetUserNum() FIXME: Finish GetUserNum()…
