I have been trying to write a Newton's Method program for the square root of a number and have been failing miserably...
#include <iostream>
#include <cmath>
using namespace std;
int main() {
double x1;
double y;
double x0;
[Code] .....
I'm working on a c program that generates approximations of square roots based on newton raphson method. I worked out the approximations with another method I learnt and I know this program does fine. But I don't get the concept of epsilon. Below is the code for the program
Code:
#include<stdio.h>
// function to compute absolute value
float absoluteValue(float x)
{
if(x < 0)
x = -x;
[code]....
The text I worked this code from uses the epsilon value arbitrarily. how is the epsilon value selected? I tried using this formula to derive the square root of 45. On paper I can go as far as 6.8 something. But once this value is reached it's still bigger than epsilon, so shouldn't the code keep running? The program generates 1.41 for 2, but since it could go further why does the while loop in squareRoot function terminate?
I am writing a program to find the square root of a number. I am using the Newton-Raphson method..Just to clarify a bit of the code.. fabs(1/(x+1)) < 0.001 is to check for relative error..
EXAMPLE: for user entry of 100 if the iteration process ends in 10.055 the answer will return as 10 which is correct. But it isn't doing that.
It compiles I then proceed to run it..prompts me "Enter a number to find the square root of: I type 100 then hit enter...
"The square root of 100 is -1077834936"
My first time writing a program from complete scratch.
And I know there is a sqrt() function...just wanted to write my own.
Code:
#include <stdio.h>
#include <math.h>
double mysqrt(double a);
int main()
{
double a, result;
printf("Enter a number to find the square root of: ");
[Code]...
i have written a function that gives me the square root of a number. Yes i know there is already a function in <cmath> that gives square roots but i thought it would be pretty challenging (and therefore fun) to try writing one on my own. I wrote my code while i was in school, listening to my Irish teacher ramble on and on about useless shit, so it's probably not the best possible way of finding the square root of a number.
double msqrt(double x) {
double adder=1;
double y = x;
for(int a=0; ; a++) {
if(y*y > x) y = y/2;
if(y*y <= x) break;

I having trouble with the rational class
here is my assignment:
Add a square root function to the rational class. Have your program print the square root of any rational number. I want to find the square root for numerator and denominator separatetly. divide the answer to get decimals and convert the decimal to fractions. i got till geting the decimal but i want to convert it back to a simplified fraction
// finding greatest common factor
int gcd(int a, int b)
{
if (b == 0)
return a;
else
return gcd(b, a % b);
}

I tried to check the rational or irrational numbers after we take the square root. i dont get the formula. for eg. squareroot of 64 is 8 and it is rational. square root of 2 is irrational. how to check it in c++..

I am able to display a filled and hollow square by themselves, but I can't seem to be able to get them side by side.
So this is my code so far:
[/
#include <iostream>
using namespace std;
int main()
[Code]....
I can get the hollow square to show up, but the first square just shows up as a single line instead of a square. It seems that it ignores the first if statement in the second loop. I've tried not using an if statement in the second loop but it didn't seem to work either.
I want to make program to square the numbers from 1 to 20. i have written this program, it's running but not giving the required answer.i think it is giving a garbage value...

I want to write how many times a method is called. The first class houses a method that I want to count from the second class how many times it is called. what I am able to achieve so far is that it only writes out how many times it is called but what I want is that it should be like a counter like this: if called ofr 5 times it should print:
1
2
3
4
5
and not just 5.
First class
public static int count = 0;
public void Login(String LoginUsername, String LoginPassword) {
count++;
}
Second class
int i = LoginReusables.count;
i++;
System.IO.File.WriteAllText(@"C:Usersken4wardDesktopTidyWriteLines.txt", i.ToString());
Create a user-defined program that will compute the price per square inch of a cake using an “overloading”. The cake could be a circle or a square type. In the main function, ask for the price of a circle cake and its diameter, while for the square cake, ask for the price, its length and width. The process must be done inside the different function of each cake. (Note: two sub function for the computation of a circle and a rectangle)
Note that when I made this program something weird happen. After inserting the name, all things follow.

I've been trying for more than one month to access a method found in a library called libcocosnas_static.a. I'm using Cocos2d-X version 2.0.4. The library has been used many times by my company to make games using cocos2d-1.0.1-x-0.12.0 without any problem.
This is what I've done:
1- I added the include paths of the library to both eclipse and Android.mk
2- Included the .h file using #include "NASPlatformUtil.h"
3- Added the libcocosnas_static.a file to the proj.androidobjlocalarmeabi folder
4- Added "LOCAL_WHOLE_STATIC_LIBRARIES += cocosnas_static" to the Android.mk file
5- Called the function using: NASPlatformUtil:: openUrl("http://xxx.xxx.com/");
I can right click on the function, click Open Declaration and get it without any problem, but the compiler keeps on giving me that dreaded error...

I have a question similar to the one here: [URL] .....
The main difference is I would like to pass a method of derived class as a parameter to some other method in its template base class.
template <typename BaseType>
class Base {
public:
typedef void (Base::*Callback)(int A);
[Code] .....
The above is an example which does not compile. My compiler complains that the two BaseMethod() calls in DerivedMethod() are invalid uses of non-static member function.
Is this not possible to do, or is my syntax simply wrong? All I want is to be able to pass as an an argument to a method in the base class from the derived class some callback as a variable for the base class to invoke later.
4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.

What are the steps to get it 4 to the root?
Any way to travel from a leaf to the root. For example I search the tree to find the leaf i want and then trace/record the path back to the root.
