Write a C program that utilizes the ComplexNumber data type defined below, ----- Start of Data Type Definition ----- typedef struct _ComplexNumber { double real; // real part double imag; // imaginary part} ComplexNumber; ----- End of Data Type Definition ----- The following behavior should be implemented: 1. Declare three ComplexNumber variables 2. Initialize the first complex variable as follows: ---->> real part = 0.5, imaginary part = -0.5 ---->> Print the initialization info on the screen 3. Initialize the second complex variable as follows: ---->> real part = -1.75, imaginary part = 0.5 ---->> Print the initialization info on the screen 4. Calculate the sum of the first and second complex variables ---->> Store the results in the third complex variable ---->> Print the results on the screen 5. Calculate the difference, i.e., first complex number minus second complex number ---->> Store the results in the third…

Code a C program with the following:i. Write a C function with the following requirements:• The function must receive a string as a function input parameter.• The function must return a new string, whose contents are equal to thereversed input string. E.g. if input parameter is the string “A1B2C3” thefunction will return the string “3C2B1A”• The original string, used as input parameter, should not be modified in anyway.• The function must be able to work with strings of any size.ii. Write the main function, which asks user for input, calls the previously createdfunction, and prints the resulting string.iii. What is the expected output when executing the program mentioned in theprevious point, when you enter your number(123456789 9 digits) as input?Notes:1. Your program must include and make use of at least one user-defined functionprototype, to ensure code reusability.2. The program must include the appropriate libraries3. The program’s variables must be sensibly named.4. The code must…
Implement in C Programming 7.11.1: LAB: Student struct Given main(), build a struct called Student that represents a student that has two data members: the student's name (string) and the student's GPA (double). Assume student's name has a maximum length of 20 characters. Implement the Student struct and related function declarations in Student.h, and implement the related function definitions in Student.c as listed below: Student InitStudent() - initializes name to "Louie" and gpa to 1.0 Student SetName(char *name, Student s) - sets the student's name Student SetGPA(double gpa, Student s) - sets the student's GPA void GetName(char* studentName, Student s) - return the student's name in studentName double GetGPA(Student s) - returns the students GPA Ex. If a new Student object is created, the default output is: Louie/1.0 Ex. If the student's name is set to "Felix" and the GPA is set to 3.7, the output becomes: Felix/3.7 main.c #include <stdio.h> #include <string.h>…
Answer this question in C++ Programming: Define a structure called Date with month, day and year as its only data members, Time with hour and minute as its only members and Event with desc (a c-string for description of maximum size 80), date (of type Date) and time (of type Time). Write a readEvents() function that will keep asking the user if he or she wants to add a new event. As long as the user answers with a 'y' or 'Y', allocate memory dynamically for an Event structure, storing the pointer returned by new in the array of Event pointers and then read the Event data from the keyboard and store them in the Event just created. Dates should be entered like 5/21/20 and times as 10:15. When finished entering the Events, the function will return the number of Events entered. Write a sort-desc() function to sort the Events by their description by rearranging the pointers (rather than the structures), by passing it the array of pointers and the number of Events created. Use a swapPtrs()…
Problem: Write a C++ program that would implement the function called filterString which accepts a string s that contains numbers and letters mixed up. The function must return an integer corresponding to the numbers in s in the order that they appear. If there are no numbers in s, the function should return 0. TEST CASES: filterString(‘123’) = 123 filterString(‘abc’’) = 0 filterString(‘aa 112 3dd’) = 1123 ASSUMPTIONS Assume that all the inputs are strings (no need for try-catch method)
