- pointers as Arguments:In the C programming language there is no pass-by-reference syntax to passa variable by reference to a function. Instead a variable is passed by pointer(just to be confusing, sometimes passing by pointer is referred to as pass byreference). This Practice Program asks you to do the same thing as C.Here is the header for a function that takes as input a pointer to an integer:1. void addOne (int ∗ptrNum )Complete the function so it adds one to the integer referenced by ptrNum.Write a main function where an integer variable is defined, give it an initialvalue, call addOne, and output the variable. It should be incremented by 1.PROGRAMMING LANGUAGE: C++ You need to store hiring date and date of birth for teachers, and for students store their admission date and date of birth. You need to create a Date class for this purpose. Create objects of Date class in Teacher and Student class to store respective dates. You need to write print function in Teacher and Student classes as well to print all information of Teachers and Students. You need to perform composition to implement this task. Create objects of Teacher and Student classes in main function and call print function for both objects. Print Date class here. Print updated Teacher class here. Print updated Student class here. Print main function here. Print Outputshere.In C/C++, True or False: A function that changes the value of a variable passed by reference also changes the value of the original variable. A variable's type helps define the amount of memory it takes to hold a value of that type.
- Average grades bar chart Write a python program grades.py that reads a file of assignment grades and draws a bar chart of the average grades for each assignment. Save the figure as grades.png in the current working directory. The format of a line in the file is: assignment_type grade Note that there is a single space between the assignment type and the grade. E.g. exam 92.80 Your program must contain the following functions: Function name Function description Function input(s) Function return value(s) get_grades() This function takes a file name as input and populates a dictionary containing the assignment types and grades. Filename string Dictionary of grades main() This function prompts for the grades file name. Next, it calls the functions get_grades(). Next, it draws the bar chart of the average grade for each assignment. Hint: You can use the mean function of the statistics module to calculate the average of a list. None None Use the starter…C++ printSmaller is a function that accepts two int parameters and returns no value. It will print the value of the smaller one parameters. The function protoype is as follows: void printSmaller(int num1, int num2); write the statments to read two integers and call this function to display the smaller one.5. A function can return a value of an enumeration type. True False
- In C programming language: Write a function that takes 3 int arguments and returns the largest of the 3.Programming Assignment Create a program application using C#, C++, or your preferred software for a small Employee Payroll system using one dimensional arrays. Include the following for at least 5 employees for a period of 3 months (assume the employees are paid monthly) a. hourly wages b. monthly earnings c. annual earnings d. monthly deductions (look the basic deductions) e. annual deductions f. net pay g. gross payStudent Registration System is an approach that enables colleges and universities to better supervise a growing number of enrollments. Create a menu system for registration program in c++ that asking an input based on the choices below. If the input is A then the program will ask for name and program (course) store in two arrays, if B then the program will display all the data stored on the array and the program will be terminated only if the input is E. Apply also function on the program: Menu System – 1st Way of Function Add Student – 4th Way of Function Example: REGISTRATION SYSTEM: A - Add Student B - View ALL E - Exit Choose: A Name: John Lloyd Program: CpE REGISTRATION SYSTEM: A - Add Student B - View ALL E - Exit Choose: B Name Program…

It should take in two arrays (the first array should be of size n and the second array should be of size n+1). The function should also take in a position and a number. It should copy the first array into the second array and place the new number at the proper position. In other words, you are creating a function that inserts a value into an array.
