Language :c++ question: Implement another class with name Department which is composed of one manager and multiple employees (use employee array) as data members. Another data member of Department is ProjectName that is just a string data member. Write a function in Department to take Manager Name, Employee names and ProjectName from user. Insert these records in a text file and print screenshot of that text file.
An array of int named a that contains exactly five elements has already been declared and initialized. In addition, an int variable j has also been declared and initialized to a value somewhere between 0 and 3. Write a single statement that assigns a new value to the element of the array indexed by j. This new value should be equal to twice the value storedin the next element of the array (i.e. the element after the element indexed by j). Do not modify any other elements of the array!
Please use C as the programing language.
Write a function that takes (i) a FILE pointer (e.g. FILE *fp) type variable, (ii) an array of student struct (that you defined in the previous question), and (iii) the number of valid elements in that array as parameters, and write those elements in a file named "students.dat". This function should return 1 if it can successfully open this file; otherwise, it should return 0.Please use C language
*C Programming This exercise is to help you learn how to debug compiler warnings/errors and other common errors in your code. For each part labeled P(n), there is a warning/error/problem that goes with it. Write down what the issue was in the `Error:` section of each problem.

A university is analysing students' academic performance in a course using an application. As shown below, the application generates a list of final marks and an academic performance report: The following information is required to generate the final mark listing and academic performance report: Course details The course details to be stored in the program include a list (array) of final marks, number of students, a list (array) of the distribution of frequencies of grades. The final marks: 75B+ 79B+ 88A 96A+ 90A+ 80A 76B+ 76B+ 79B+ 76B+ 75B+ 91A+ 92A+ 82A 84A 76B+ 97A+ 93A+ 95A+ 82A 78B+ 81A 81A 82A The final marks are stored in a text file named marks.txt.

Write a function named swapFrontback that takes as input an array ofintegers and an integer that specifies how many entries are in the array. Thefunction should swap the first element in the array with the last elements inthe array. The function should check if the array is empty to prevent errors.The header file for the swapFrontback() is:swapFrontback.h:double swapFrontback (int [] arr,int size);Write a driver (main.c) to test your function with arrays of different lengthand with varrying front and back numbers. Print the array elements beforeand after the swap in the main.c.Sample Run: Original Array: 1 2 3 4 5 6 FrontBack Array: 6 2 3 4 5 1
Create a new file in C++ and save it as lab12_XYZ.cpp Consider rolling two six-sided dice. While the result of each throw is independent of all rolls that have come before, we can still calculate the odds of rolling any given number between 2 and 12. This program will calculate those odds by generating a large number (100,000) of random values (i.e. "rolling the dice") and storing the results in an array. When all values have been rolled, we will display the results (counts and odds to 2 decimal places) to the user. x x 2 3 4 5 6 7 8 9 10 11 12 //value for sum of 2 dice rolls +---+---+---+---+---+---+---+---+---+---+--- | | | | | | | | | | | | | | //counters for number of times value is rolled +---+---+---+---+---+---+---+---+---+---+---+---+---+ 0 1 2 3 4 5 6 7 8 9 10 11 12 //array index In Lab 5, sample code was provided for generating a random number.

Step 1: Read your files! You should now have 3 files. Read each of these files, in the order listed below. staticarray.h -- contains the class definition for StaticArray, which makes arrays behave a little more like Python lists O In particular, pay attention to the private variables. Note that the array has been defined with a MAX capacity but that is not the same as having MAX elements. Which variable indicates the actual number of elements in the array? staticarray.cpp -- contains function definitions for StaticArray. Right now, that's just the print() member function. 0 Pay attention to the print() function. How many elements is it printing? main.cpp -- client code to test your staticarray class. Note that the multi-line comment format (/* ... */) has been used to comment out everything in main below the first print statement. As you proceed through the lab, you will need to move the starting comment (/*) to a different location. Other than that, no changes ever need to be made to…
