Use all programming techniques that you have learnt so far, approximate the root of f(x) = x3 - 3 with the bisection method starting with the interval [1, 2] and use εstep = 0.1 and εabs = 0.1.
Write a flowchart for your design.

Hints:

Initial Requirement:

We have an initial bound [a, b] on the root, that is, f(a) and (b) have opposite signs.


Iteration Process:

Given the interval [a, b], define c = (a + b)/2. Then
•if f(c) = 0 (unlikely in practice), then halt, as we have found a root,.
•if f(c) and f(a) have opposite signs, then a root must lie on [a, c], so assign b = c,.
•else f(c) and f(b) must have opposite signs, and thus a root must lie on [c, b], so assign a = c..


Halting Conditions:

There are three conditions which may cause the iteration process to halt:
1.As indicated, if f(c) = 0..
2.We halt if both of the following conditions are met: ◦The width of the interval (after the assignment) is sufficiently small, that is b - a < εstep, and.
◦The function evaluated at one of the end point |f(a)| or |f(b)| < εabs..
.

If we halt due to Condition 1, we state that c is our approximation to the root. If we halt according to Condition 2, we choose either a or b, depending on whether |f(a)| < |f(b)| or |f(a)| > |f(b)|, respectively.

Running on a particular treadmill, you burn 3.9 calories per minute. Create an application that uses a loop to display the number of calories burned after 10, 15, 20, 25, and 30 minutes.

Write a C# program that:
• Asks the user to enter the desired weekly pay rate.
• Reads the desired pay rate from the user.
• Checks the pay rate if it is more than or equals to 1000, prints the message "You
should work more than 35 hours.".
• Checks the pay rate if it is between 500 and 1000, prints the message "You should
work between 25 to 40 hours.".
• Otherwise, prints the message "Your weekly pay rate is not correct.".

Is there any difference in allocation of memory to the members of the class and object. Justify the Statement that “the Dynamic Constructor helps in utilizing the memory efficiently. Illustrate with the help of an example.

I have a button that stores strings in an array but I can click it several times and add the same value to it. I just want to know how to code that when I press the button it will prompt a message and don't add the strings to the array. Please help me. Thank you.

input N integers (ask from the user how many numbers he/she wants to input) determine and print the sum of all numbers, the average of all numbers, how many odd numbers were inputted, how many even numbers were entered and how many zeroes inputted

Hey. I just wanted to know a couple of things about programming. So first off im only 15 and i enjoy programming for windows phone mobiles. In this case it's the basics. But i want to improve from where i am. I only know the basics of c# but not for windows phone c#. For the desktop it's alright and i can manage but not for windows phone. This is because the apps i make are mostly viewing and navigating. It doesn't have that many code. So in order for me to learn c# would i have to start from the very beginning as in like x# for dummies and know everything in detail or can u just learn the needed. I just want to know where i can start from. I want to focus quite a lot on c# or xmal and that's all but where can i start learning from. That's the bit i get confused at because i don't know if i need to learn the basics or just learn the bits i need.

What is the output of this C# code?
delegate void d(int i);
class P {
public static void Main() {
td(new d(ff));
}
public static void td (d sf) {
sf(-9);
sf(22);
}
public static void ff (int i) {
System.Console.Write("{0} ", -(i-2));
} }

Create a program that first asks for two integer values A and B. Your program should then pick a random number between A and B and keep it secret. Then ask the user to guess what the number is. The program should continue to ask the user to guess, until the user gets the correct answer. Each time the user makes an incorrect guess, the program should tell the user if the guess was too high, or too low. The program should also tell the user if the guess was outside the range between A and B. Important Notes 1. The numbers A and B must be different. The program should keep asking for new inputs until it gets two different numbers. 2. A and/or B could be negative. The program should work with negative values. 3. The numbers A and B could be given in either order (A < B or A > B). The program should not care and be able to accept them in either order. 4. The program should pick a number at random between A and B inclusive (the random number might be either A or B). 5. The program should tell the user if a guess is
