Upon calling the function display the average determined by the user-defined function

Use a function called double detAverege() to determine the average percentage. The function will receive 3 integer parameters. The 3rd mark will be passed by reference.

Write a C++ code that will prompt the user to enter marks of 3 students. Determine and display the lowest mark among the 3. Do not use a loop. 

A training center selects applicants into their apprenticeships program based on the needs fir apprentices in the industry. Only 5 applicants were enrolled for the year. The final mark for the student is determined by the final exam mark plus 5 Mark's if the student submitted all the assessments. Otherwise, the final mark of the student is the exam mark

Write a c++ program to determine the final mark of the student. The program should:

•Hold the names of the students and their final mark in a parallel array

•Display the names and their final Mark's in a tabular format

•Calculate and display the average mark of the student

•Calculate the highest and lowest final mark and display the name and the mark of the student with the highest and lowest final mark.

Create a class Date whose object can store a day, month and year. Include the necessary

constructors to initialize the objects and function to display the date in ‘dd/mm/yyyy’ format.

Define a non-member function findAge(Date dob, Date today) which should return the calculated

age from the input dates ‘dob’ and ‘today’. Set this function as friend to Date class. Write a main

function to read the today’s date and date of birth of a person from the user and display the age

of that person by calling the proper function.

- Roll a six-sided die 6000 times. Then show the output frequency elements 1-6 in

tabular format. Use the following

srand( time( 0 ) ); // seed random-number generator

face = 1 + rand() % 6 ; // generate rand face from 1:6

create B[face] list to count the number of occurrence the faces 1 -6,

Show the output as

Face Frequency

1 1003

2 1004

3 999

4 980

5 1013

6 1001

Write a main program to run the following functions:

void inp

ut_array(double a[ ]); // to input an array

void count( double a[ ], int &odd, int &even) // count odd and even numbers, return by
