(Complex Class) Consider class Complex shown in Figs. 18.14–18.16. The class enables operations on so-called complex numbers. These are numbers of the form realPart + imaginaryPart* i, where i has the valuea) Modify the class to enable input and output of complex numbers via overloaded >> and<< operators, respectively (you should remove the print function from the class).b) Overload the multiplication operator to enable multiplication of two complex numbersas in algebra.c) Overload the == and != operators to allow comparisons of complex numbers
(Enhancing Class Date) Modify the Date class of Figs. 17.13–17.14 to perform error checking on the initializer values for data members month, day and year. Also, provide a member functionnextDay to increment the day by one. Write a program that tests function nextDay in a loop thatprints the date during each iteration to illustrate that nextDay works correctly. Be sure to test thefollowing cases:a) Incrementing into the next month.b) Incrementing into the next year.
3.27 LAB: Login name Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first six letters of the first name, followed by the first letter of the last name, an underscore (_), and then the last digit of the number (use the % operator). If the first name has less than six letters, then use all letters of the first name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: MichaeJ_1 Ex: If the input is: Nicole Smith 2024 the output is: Your login name: NicoleS_4
(Enhancing Class Time) Modify the Time class of Figs. 17.4–17.5 to include a tick memberfunction that increments the time stored in a Time object by one second. Write a program that teststhe tick member function in a loop that prints the time in standard format during each iterationof the loop to illustrate that the tick member function works correctly. Be sure to test the followingcases:a) Incrementing into the next minute.b) Incrementing into the next hour.c) Incrementing into the next day (i.e., 11:59:59 PM to 12:00:00 AM).
10 - In an examination, 500 students appeared. Out of these students, 38 % got A+ grade, 45 % got B+ and the remaining just passed. Assuming that no student failed, find the number of students who got A+, B+ and the number of students who just passed.(Python code)
21.7 LAB: Login name (Use python) Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first five letters of the last name, followed by the first letter of the first name, and then the last two digits of the number (use the % operator). If the last name has less than five letters, then use all letters of the last name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: JordaM91 Ex: If the input is: Kanye West 2024 the output is: Your login name: WestK24
10.25 LAB: Quadratic formula Implement the quadratic_formula() function. The function takes 3 arguments, a, b, and c, and computes the two results of the quadratic formula: x1=−b+b2−4ac2a x2=−b−b2−4ac2a The quadratic_formula() function returns the tuple (x1, x2). Ex: When a = 1, b = -5, and c = 6, quadratic_formula() returns (3, 2). Code provided in main.py reads a single input line containing values for a, b, and c, separated by spaces. Each input is converted to a float and passed to the quadratic_formula() function. Ex: If the input is: 2 -3 -77 the output is: Solutions to 2x^2 + -3x + -77 = 0 x1 = 7 x2 = -5.50
11.4.1: Leap year - functions. A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are: 1) The year must be divisible by 4 2) If the year is a century year (1700, 1800, etc.), the year must be evenly divisible by 400 Some example leap years are 1600, 1712, and 2016. Write a program that takes in a year and determines whether that year is a leap year. If the input is 1712, the output is: 1712 is a leap year. If the input is 1913, the output is: 1913 is not a leap year. Your program must define and call a function: Function OutputLeapYear(integer inputYear) returns nothing The function should output whether the input year is a leap year or not. Need program written in the coral language
(7) Implement the ShortenSpace() function. ShortenSpace() has a string parameter and updates the string by replacing all sequences of 2 or more spaces with a single space. ShortenSpace() DOES NOT output the string. Call ShortenSpace() in the PrintMenu() function, and then output the edited string. Ex: Edited text: We'll continue our quest in space. There will be more shuttle flights and more shuttle crews and, yes, more volunteers, more civilians, more teachers in space. Nothing ends here; our hopes and our journeys continue!
Transcribed Image Text 7-a) Danish works as a constructor. Like all constructors, he is also a beer fan. He likes beer so much that has K cups of beer daily. However, having more than K cups doesn't suit him, because the excess beer won't allow him to sleep at night. Danish's working day is divided into N periods. For every period, he knows how many kilobytes of weight he can lift. During each of the periods, Danish can either have or not to have one bottle of beer. If he is having a bottle of beer in some period, the amount of work in this period drops to zero. But he also gets a productivity boost, if he decides to skip beer during a period and the last bottle of beer, he had was no more than D periods ago, the amount of work during such a period is M times the usual.
7.23 LAB: Winning team (classes) Given main(), define the Team class (in files Team.h and Team.cpp). For class member function GetWinPercentage(), the formula is:teamWins / (teamWins + teamLosses) Note: Use casting to prevent integer division. Ex: If the input is: Ravens 13 3 where Ravens is the team's name, 13 is number of team wins, and 3 is the number of team losses, the output is: Congratulations, Team Ravens has a winning average! If the input is Angels 80 82, the output is: Team Angels has a losing average.
