C++ :: Calculate Complex Numbers Through Multiplication And Addition
Feb 28, 2013Below is a code that is used to calculate complex numbers (a+bi, where i = sqroot (-1)) through multiplication and addition.
However, on my output file, no Header is being printed; the only thing that is being printed is "8 + 7i + = "
"complex.h" is included at the end of the code.
Code:
// Trey Brumley// CMPS
// Dr. Tina Johnson
// March 1, 2013
// Program 2: Classes
// This program will demonstrate the use of classes by using a custom "complex-number" (a+bi) class.

C++ :: Overloading Operator For Complex Numbers
Jul 14, 2013I have a program written to add 2 complex numbers. Everything is working, except when the sum gets written, it gives me a number that is way off.
#include <iostream>
#include <complex>
#include <fstream>
#include <cstdlib>
#include <math.h>
class complex {
public:
complex();
complex(double r, double i){
[Code] .....
And my output ends up being Enter a complex number (a+bi) :
1+2i
Enter a complex number (a+bi) :
2+3i
x 1+2i
y 2+3i
4.8784e-270+4.85593e-270i

Visual C++ :: Using Imaginary Number - How To Declare Complex Numbers
Aug 13, 2013I created an algorithm that uses imaginary numbers. It is fine on Dev C++, and now I am trying to port to VS2008. I figured out most things, including how to declare complex numbers. However, I've been having an incredible hard time trying to figure how to use the " i " number! For example:
In Dev C++:
Code:
z_cmplx = cexp(I * f1/Fs * 2 * PI);
Where "I" is a macro from the library!
In VS2008:
Code:
z_cmplx = std::exp(I * f1/Fs * 2 * PI);
Although I DID include <complex> library just like I did before, the compiler gives me: error C2065: 'I' : undeclared identifier.
C++ :: How To Linearize A Complex Non-uniform Tree
Oct 25, 2013I have a tree structure that works likes this.
Each node (if its a 'normal' node) can have 2, 3 or 4 children. I know how to linearize a normal quadtree though it is not memory efficient in this case as the linearization only works for full trees. I'm okay with holes though.
But my tree is slightly odd in that it has non-normal nodes. For example, two leaves will point to a 'dead' node and that dead node has 3 children. Sometimes, 3 leaves will point to a dead node and that dead node will have 2 children. Sometimes, 4 leaves will point to a dead node and that dead node will have 4 children.
So normally, a node will only have one parent and multiple children or it'll just be a leaf. But there are dead nodes that can have 2, 3, or 4 parents and will subsequently have 3, 2 or 4 children respectively.
This is for point location within a Delaunay triangulation and operates off of the idea of volume spanning.
What I abstracted in my code is a 2-to-3, 3-to-2 and 4-to-4 flip. The idea is ,we take 2 tetrahedra and replace them with 3 good tetrahedra but they span the same volume which is good for point location.
As of now, the code that I have works fine. It triangulates tetrahedra and repairs them accordingly but for certain inserts, the search algorithm takes incredibly long and I'm trying to fix that.
I figured a linear structure would be a good attempt so how to linearize a tree that behaves almost polymorphically.
C :: Simplify Complex Declarations Using Typedef
Jan 2, 2014I have some complex declarations to simplify with typedef I have done a try
1. Code:
char (*x[10]) (int);
/* typedef char FUNC(int);
typedef FUNC *FUNC_PTR;
FUNC_PTR x[10]; */ Why we don't use * symbol in the last statement in front of FUNC_PTR?
2. Code:
int (*x(int))[5] I can't do this :/
3. Code:
float *(*x(void))(int);
/* typedef float *FUNC(int);
FUNC *x(void); */
C++ :: Complex If Statement Does Not Include NOT Operator
Feb 7, 2015I'm not sure if I was some weird syntax problem or the way Ive ordered things. But a conditional statement I have created is not performing the way I want it to.
else if ( !( xDif == -1 && yDif == 1 && prevXDif == 1 && prevYDif == 0 ) )
{
foundArr[lastX][lastY] = 1;
}
When debugging, the condition was activated with the values:
xDif = -1
yDif = 1
prevXDif = -1
prevYDif = 0
However, I want the condition not to follow through as I am using the 'NOT' or '!' operator to negative the entire statement. For some reason, the line of code within the else if is still running.

C/C++ :: Menu Driven Complex Calculations
Mar 18, 2015//complxCalc.cpp//
#include "complx.h"
using namespace std;
ifstream infile ("in.dat");
int main() {
int i = 0;
complx tempComplx;
double d = 4.5;
[Code] ....
//in.dat//
(4,4) (6,7) (2.5, 9.3) (3,8.4) (13, 26.5) (2.2, 3.4)
My plan is to make this a menu driven program, I have already got the program to give the answers but now I want it to give the user choices as well. The first step in this project is to add a menu to the program. The first menu the user sees should ask the user if the program will be taking input from a file or from the user directly via the keyboard. Regardless of option chosen, the user should then be prompted to specify whether a multiplication,subtraction or addition operation should be performed.
If the user originally chose the file input method then the program should proceed to display to the screen the results of those operations on each pair of data elements in the file and terminate. If the user chose to input via the keyboard then the user should be prompted to input the two numbers, perform the operation on those two numbers and display the results to the screen and ask the user which mathematical operation they would like to do next and continue in this manner until the user chooses to exit the program via a menu option. Fortunately the only file that needs to be edited are in.dat and complxcalc.cpp files.
C :: Creating Struct Which Represents Complex Number
Feb 26, 20151 create a struct called complex which reprensts a complex number . both the real and imaginary compoents should be represented as doubles . ( 1 marks) .
2 write down a function called magnitude which has one parameter ( a struc complex) and a return type of double . it should return the maginude of the given parameter . ( 3marks) .
3 write a function called find_largest which has two parameter (one of type struct complex const * and the other type int) and a return type of struc complex . the two parameter represent an array of complex numbers and number of elements in that array . the function should return elements from array which has largest magnitude . this fucntion must called the magnitude function . ( 5 marks)
4 write a main function . your main fucntion . Your main fucntion should repeately prompt the user for complex number , storing them in an array. you should continuing reading in complex number until the user enters in both componets , at this point you should stop . you should not make an assumptions how many complex number the user will enter , ( i.e use realloc) after reading in complex numbers from the user you should print out real and imaginary components of the complex number with the largest magnitude.

Code:
#ifndef COMPLEX_H
#define COMPLEX_H
#include <iostream>
using namespace std;
class Complex {
friend ostream & operator<<(ostream &, const Complex &);

cout << c3 is Working fine But cout << c1 + c2 is not giving me correct output!
C# :: Creating Complex Number Calculator - Convert String To Ints
Sep 18, 2012I am working on an assignment to create a Complex number calculator. In this assignment I am to ask the user for input to the calculator. We are given a sample run output that looks like this.
Enter operand1: 3 4
operand1: (3, 4)
Enter operation : +
Enter operand2: 1 2
(3, 4) + (1, 2) = (4, 6)
My question is how would I take from the user: an integer followed by a space followed by another integer and convert that into two seperate accessible int values that I can save as real and imaginary values.

C++ :: If Statement Multiplication By Zero
Mar 28, 2013I want to set an integer to zero when it easy equal to another integer, but it seems that the program for some reason won't set the integer to zero. Here is the example of that code:
#include <iostream>
using namespace std;
int main () {
int n = 2;
int r = 2;
if(n==r)
n++;
r*0;
cout << " n is " << n << endl;
cout << " r is " << r << endl;
}
What am I doing wrong, it should say that "n is 3" and "r is 0".

May 25, 2013 how to print a multiplication table of 2,3 ,4 or any table using functions in c++.. ?
Remember using "Functions" e.g Multiplication(int x)

C++ :: For Loop Multiplication - X Factorial
Oct 18, 2013int main() {
int x;
int y=1;
for(x=1 ; x<=12 ; x++ , y=y*x ) {
cout<<y<<'
';
}
}
This code give x! ( x factorial).
whenever ,in x<=12 , we change the 12 to any number n where n>=1 and n<=12
the code works and give the (x factorial)
for example 12!=479001600
the problem begins with the number 13.
when we put 13 like this x<=13 or for(x=1 ; x<=13 ; x++ , y=y*x )
the compiler gives a wrong result : it gives 1932053504 which is wrong because the true result is 6227020800
C++ :: Using Vectors For Manual Multiplication?
Jan 15, 2013I'm trying to solve Project Euler 16 where you have to calculate 2^1000. SO I made a program that would solve multiplying a number b a single digit factor through manual multiplication in a vector, just to test things out.
The problem is when I take things out of main and try to make a separate function, the original number is never multiplied.
Here's my code with functions...
/*Using vectors manually to multiply a number to a positive power.*/
#include <iostream>
#include <vector>
using namespace std;
void print_vector(const vector<int>& v);
[code]....
Here is the other code, not using functions but even if I use an extra for loop to multiply by the same factor several times, it still does the same thing.
/*Using vectors manually to multiply a number by two (or any single digit factor).*/
#include <iostream>
#include <vector>
using namespace std;
void print_vector(const vector<int>& v);
[code]....
