Write a function named "eliminate_duplicates" that takes an array of integers in random order and eliminates all the duplicate integers in the array.

The function should take two arguments:

(1) an array of integers;

(2) an integer that tells the number of cells in the array.

The function should not return a value, but if any duplicate integers are eliminated, then the function should change the value of the argument that was passed to it so that the new value tells the number of distinct integers in the array. 

Write a C++ program to make a structure of a student consisting of integer age, char name and structure roll number that further divides into department, session, registration number and degree. Set and display all the values from main function and display the record on screen to present the access of structure within structure. You have to by access structure using pointer type variable of structure

Write a function in C++ to calculate and return the roots of a quadratic equation ax2 + bx + c = 0. 

Return x1 and x2 through

parameter of the function. The prototype of this function is defined by:

void solveEquation(int a, int b, int c, float *x1, float *x2);

Write a function in C++ program to exchange two numbers. 

These two variables are passed through parameters of the

function using pointer. void exchange(int *a, int *b)

Print a welcome message to the screen as follows:

We bid welcome to the ladies of Beauxbaton and our friends from the north, the sons of Durmstrang.

Your task is to implement this:

• A member variable that will hold the annual interest rate of the loan. Its default value will be 2.5.

• A member variable that will hold the number of years for the loan. Its default value will be 1.

• A member variable that will hold the loan amount. Its default variable will be 1000.

• A default constructor.

• Another constructor that has interest rate, years, and loan amount as its parameters.

• A member function that returns the annual interest rate of this loan.

• A member function that returns the number of the years of this loan.

• A member function that returns the amount of this loan.

• A member function that returns the monthly payment of this loan.

• A member function that returns the total payment of this loan.

Enter yearly interest rate, for example 8.25: 10

Enter number of years as an integer, for example 5: 5

Enter loan amount, for example 120000.95: 300000

The monthly payment is 6374.11

The total payment is 382446.80
