- In c++, please and thank you! Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.The following test score are obtained from a class with eight students: 75,24,48,65,86,45,56,94 Write code in C# to initialize these values into an array named testScore using the implicit declaration method.PROGRAMMING LANGUAGE: C++ Write a program which has a class named FileHandlerto read StudentName, MarksObtained from the attached picture. The class should have a function which calculates grade for a student and then adds it in a new column i.e. Grade. The grade should be calculated considering the following criteria. A: 87-100, B+: 80-86, B: 72-79, C+: 66-71, C: 60-65, D: 50-59, F: 0-49 The file should be saved once grade for all students is calculated. Write the driver program for executing the task.
- Topic: pointers, dynamic array and command line arguments Write a complete C++ program named “showHelp” that accepts command line arguments. It checks whether there is a command line argument of “/help” or“/?” or “-help” followed by a topic number. It will print out “yes, topic number(<number>) if there is one. Otherwise, it prints out “no, topic number(N/A) For example, if you run this program with correct arguments as follows, it willprint out yes and its associated topic number respectivelyshowHelp /? 101showHelp /debug /help 102showHelp /print /help 103 /verboseshowHelp -verbose -debug -help And if you run the program with invalid arguments, it will print no, in all casesshowHelp -helpshowHelp 101 /?showHelp 101 102 /help /verboseshowHelp /? /help -helpNote: command line arguments are simply an array of pointers to C-string. example code: #include <iostream> using namespace std; int main(int argc, char** argv){...}In C++ Write the definition of a void function that has two parameters: an array, and an integer parameter that specifies the number of elements in the array. The functions swaps the first and last elements of the array.C++ Coding Write a program that asks a teacher to enter the student's name and the grades received on her quarterly exams. The datatype for the student's name could be a string and the four grades should be entered in an array of data types int. Test scores are on the base of 100. REMINDER: sum and cap CANNOT be integers. The main() functions describe the average function with the following title line: double avg( int grades[], int cap ) The program prints the student's name, her four grades, and her average grades The main() function also uses the following print function: void print( int grades[], int cap);

Write a program that dynamically tracks these courses using an array of object pointers. Every course (both curriculum and continuing education) has a course id, title, room number, and number of contact hours. A curriculum course has credit hours and tuition rate. Tuition is calculated by multiplying the course's credit hours by tuition rate. A continuing education course has a flat fee (cost). Implement a show() function in every class that displays the data in the object. Part A: Create an inheritance-based collection of classes to represent these different courses. Include code in main to test your work by instantiating objects of the two derived classes. Part B: Modify your program. Remove the objects you created in main to test the classes. Modify the base class so that show() becomes a virtual class. In main, create a single array capable of holding pointers to objects of both…
- To be done in C++ Brief Description: This program will ask the user to enter details about a class of students, one student at a time. These details include first name, last name, age, and grade. The user should be able to add up to 10 students, which will be stored in an array of structs. Details: The program should first ask the user how many students they wish to enter, up to 10. If a user enters a number less than 1 or greater than 10, the program should keep asking the user the number of students until the number is between 1 and 10. Once this information is known, the program should proceed to ask for each student’s first name, last name, age, and grade. Once all the student information has been entered by the user, the program should output all the student information to a file called “students.txt”. For each student entered, this file should contain 4 lines of information. The first line should be the first name. The second line should be the last name. The third line…To be done in C++ Brief Description: This program will ask the user to enter details about a class of students, one student at a time.
