please help me to add the recursive function thankyou

Create a class heater that contains a single integer field temperature. Define a constructor that takes no parameter. The temperature field should be set to the value 15 in the constructor. Define the mutates warmer and cooler, whose effect is to increase or decrease the value of the temperature by 5.

Objective:

Write a program that asks the user for the name of a file. The program should display

the last 10 lines of the file on the screen (the “tail” of the file). If the file has fewer than

10 lines, the entire file should be displayed, with a message indicating the entire file

has been displayed.

NOTE:

Using an editor, you should create a simple text file that can be used to test this

program.

26. Suppose that the tuition for a university is $10,000 this year and Write a program that computes the tuition in ten years and the total cost of four years"

increases 5% every year.

worth of tuition starting ten years from now. 27. Write a program that convert from kilograms to pounds, miles to kilometers, and from

hour to minutes based on the choice of the user. 28. Write a program that prompts the user to enter the number of students and each student's

name and score, and finally displays the student with the highest score and the student

with the second-highest score.

29. Write a program that prompts the user to enter the number of students and each student's name and score, and finally displays the name of the student with the highest score.

2. Write a float method triangle() that computes the area of a triangle using its two formal parameters h and w, where h is the height and w is the length of the bases of the triangle.

3. Write a float method rectangle() that computes and returns the area of a rectangle using its two float formal parameters h and w, where h is the height and w is the width of the rectangle.

4. The formula for a line is normally given as y= mx +b. Write a method Line() that expects three float parameters, a slop m, a y-intercept b, and an x-coordinate x. the method computes the y-coordinate associated with the line specified by m and b at x coordinate.

5. Write a method Intersect() with four float parameters m1.b1.m2,b2. The parameters come conceptually in two pairs. The first pair contains the coefficients describing one line; the second pair contains coefficients describing a second line. The method returns I

if the two lines intersect. Otherwise, it should return 0;

Creat a class called class1 and class2 which each of having one private data members .Add member function to set value say 'set value' on each class. Add one more function max() that is friendly to both classes and max() function should compare two private member of two classes and show maximum among them

write c++ program using a dynamic arrays to assign seats to pessenger

Example:

Base integer = 3

Initial factor = 2

Number of times to process = 3

Process:

1.) 2 x 3 = 6

2.) 6 x 3 = 18

3.) 18 x 3 = 54

Therefore, the output would above would be 54.

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for the 3 integer inputs required for this program and calls the getResult().
2. This getResult() function has the following details:
3. Return type - int
4. Name - getResult
5. Parameters
6. int - Base integer
7. int - Initial factor
8. int - Number of times to process
9. Description - this is a recursive function which implements the desired behavior explained in the problem description
10. The getResult() function is partially implemented already. Your only task is to add the correct recursive case.

1. In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString().
2. This preserveString() function has the following description:
3. Return type - void
4. Name - preserveString
5. Parameters
6. The string
7. Length of the string
8. Description - this is a recursive function that prints the string repeatedly. Each time it prints the string, it excludes the last character of the string until only one character is left.
9. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function.
