Write C++ Program and Test the following function:

void multiply (float a[ ], int n, float b[]);

The function multiplies the first n elements of a by the corresponding first n elements of b.

For example, if a is the array {2.2, 3.3, 4.4, 5.5, 6.6, 7.7, 8.8, 9.9} and b is the array

{4.0,–3.0, 2.0,–1.0,0.0, 0.0}, then the call multiply(a,5,b) would transform a into the

array {8.8,–9.9,8.8,–5.5, 0.0,7.7,8.8,9.9}.

Jane has opened a new fitness center with charges of 2500 per month so the cost to become a member of a fitness center is as follows: (a) For senior citizens discount is 30%; (b) For young one, the discount is 15%; and int roll_no; string name; int phone_number; }; int main(){ student p1 = {1,"Brown",123443}; student p2; p2 = p1; cout << "roll no : " << p2.roll_no << endl; cout << "name : " << p2.name << endl; cout << "phone number : " << p2.phone_number << endl; return 0; } 5. Lab Exercise: Lab Task 1: Jane has opened a new fitness center with charges of 2500 per month so the cost to become a member of a fitness center is as follows: (a) For senior citizens discount is 30%; (b) For young one, the discount is 15%; and (c) For adults, the discount is 20%. Write a menu-driven program (using structure) that a. Add new member b. Displays the general information about the fitness center and its charges. c.

Create a class Rectangle having width and length private members. The class certain a parameterised constructor for setting the width and length. It includes functions named clAire and calPerimeter that returns the area and perimeter of the Rectangle respectively. Also, overload the equality operator via friend function that compares whether two Rectangle objects are sunse or not.

In the main function, create two rectangle instances. Write necessary statement to call the above functions

Create a program using a one-dimensional array that accepts five input values from the keyboard. Then it should also accept a number to search. This number is to be searched if it is among the five input values. If it is found, display the message “Searched number is found!”, otherwise display “Search number is lost!”.

Manufacturing Date

Given a expiry date

expiryDate and number of months before expiry monthsBeforeExpiry of a product, write a JS program to find the manufacturing date.Input

• The first line of input contains a date string expiryDate
• The second line of input contains a number monthsBeforeExpiry

Output

• The output should be a single line containing the manufacturing date of the product

 main();

});

function readLine() {

 return inputString[currentLine++];

}

/* Please do not modify anything above this line */
