C++ :: Program That Takes Two Complex Number And Return Their Sum?
Oct 25, 2013
you have been tasked to write a program that takes two complex number and return their sum.However the + operator will not worl with complex numbers and you figure you need to verload the + and the assignment opeartor=.Ypu have come across the program [URL]
implement it and the client code to see it rune for the following complex numbers:
c1=3.0-4i,c2=8+4i
i have 3 files,driver.cpp,Complexnumber.cpp and complexNumber.h
complex.cpp is as follows
#include <iostream>
using namespace std;
class ComplexNumber {
private:
double real;
double image;
[code]....

I have to make a program that takes a number input from the user and prints the corresponding fibonacci sequence number. For example, for the input of 3, it should print 2 since the third term in the fibonacci sequence is 2.
I am not sure how to do this so for my attempt, I used the formula found in this website. A Formula for the nth Fibonacci number
Here is the program so far. It doesn't produce the correct output.
Code:
#include <stdio.h>
#include "genlib.h"
#include "simpio.h"
#include "math.h"
[Code]....

the only problem I have is where to add
want to play again? y
OK, I am thinking of a number. Try to guess it.
Your guess?
...
want to play again? no
Goodbye
Code :
#include <stdio.h>
#define TARGET 23
#define LOW 1
#define HIGH 100
#define TRUE 1
#define FALSE 0
#define GUESS 6
int process( int guess, int target );

1 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:
#include<stdio.h>
struct complex {
double real;
double imag;

Write c/c++ code of overloading ^operator in complex number class.
If we have two objects of complex number class as fellows,complex obj3 =obj1 ^obj2 ;
Obj3 reak and imaginary pars will be ,
Obj3.real = (obj1.real)obj2.real
And
obj3.img = (obj1.img)obj2.img

I 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.

I 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.

This code is meant to open a file and use overloaded operators for a complex number class. I am getting a lot of errors in my class declaration/definition but I am not sure why.
#include <iostream>
#include <cmath>
#include <fstream>
class CN {
public:
double real;

It is possible to change the number of operands an operator takes?
I think it is false. Am I right?

I have to make a program that takes several numbers into an array into a function, and send them back into the main function multiplied by 1.13. This is what I have so far:
#include <iostream>
using namespace std;
void connell(int&n[20])
main() {
int num[20];
[Code] ...
I do not know how to get numbers from an array from a main program to a function.

Write a C/C++ program that reads a boolean expression in sum-of-products form and generates the sum-of-minterms form (canonical form). Use single letter to represent variables. The following symbols will be used to represent operators: NOT: ~, AND: *, OR: +. Other operators won't be used.
Examples of execution:
number of variables: 2
SOP expression: ~A+B
output: ~A*~B + ~A*B + A*B
number of variables: 3
SOP expression: x*y*z + ~x*~y + y*~z
output: x*y*z + ~x*~y*z + ~x*~y*~z + x*y*~z + ~x*y*~z

I am writing a spell checker for a exercise for a class I am taking online. I have to load a huge text file of 143092 words into a hash table.
The program segfaults on word number 63197. Is there a way to debug this in gdb without having to step threw the function 63197 times.

I am writing a C++ program which takes date & time input from the user. This is then parsed into a struct such as:
struct time
{
short year;
short month;
short day;
short hour;
short min;
};
My question is: how can I convert such a struct into a time_t object, which is an unsigned long giving the time as the number of seconds elapsed since the epoch Jan 1st 1970, 00:00, as set out in time.h.
I am wondering if this can be achieved using the standard library, or whether I just need to write a function to perform the appropriate arithmetic.

Write a C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.
This is a sample output. Notice how the program prints a counter (1, 2, 3, ) for user keep track of how many numbers were entered so far. Include this feature in your program.
I have tried different ways to get the result from while loops, do while, and if-else statements. We have not done any max/min problem in class and the book was kind of vague. We have not learned arrays yet in class and I can't figure a way to compare the integers the user inputs as it is an infinite(from what I am reading) amount aloud. The problem I am seeing is the loop works and stops with the sentinel value but the INT_MIN is using the sentinel value. I also have not addressed the input of negative numbers yet with the first program I wrote, maybe one of my problems.
Code:
/*File:HW2Q3.c,
A C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.*/
/*header files*/
#include<stdio.h>
#include<limits.h>
/*****start program*****/
int main() {
[Code] ....
I have also tried this way as well, min value still comes back as -1 the sentinel value, and the else statement is being ignored. I am sure it is something silly but I am lost and confused at this point.
Code:
/*File:HW2Q3.c,
A C program that takes multiple integers from the user and finds the minimum value. The numbers entered by the user are positive integers. When the user is done entering all the numbers, the user enters the sentinel value of -1.*/
/*header files*/

I'm trying to create a program that takes an integer input and displays each digit on a new line from right to left.
An example of this would be:
Enter an integer: 657
Digit (1): 7
Digit (2): 5
Digit (3): 6
So far I have this:
#include <stdio.h>
#include <math.h>
int main() {
int i, input, output;
printf("Enter an integer: ");
scanf("%d", &input);
if(input == 0)
printf("Digit (1): 0");
[Code] ....
It works perfectly fine, but I just learned that I am not allowed to use the #include <math.h> so I have to take out floor, log, and pow.
I'm pretty sure I have to do some sort of while or for loop to get the results, but how to do it.

I'm just getting back into the swing of things after a long time of not programming. I'm trying to create a program which takes in command line arguments and prints the last one. My code is as follows:
#include <iostream>
#include <vector>
#include <string>
using namespace std;
int main() {
string x;
vector<string> arguments;
[Code]...
And the error message I receive, a simple but frustrating one, is as follows:
Enter arguments, enter STOP to stop: Segmentation fault...

Here your supposed to create a program that takes in information and formats it into three columns.
I can't seem to use the float variable unitprice with decimal places here for, if I try to use %.1f and type in an input, the program seems to skip over the second scanf function, not allowing me to put input into the third scanf function as the program runs before I can.
I can use %f on its own and it works but this creates too many zeroes(and you're supposed to set the currency limit to $99999.99).
Code:
#include <stdio.h>
int main(void) {
int itemno, month, year, day;
float unitprice;
[Code]....
So the output should look like three columns. It's just the float that is the issue here....

I was required to write a program that takes a baseball players statistics and displays there averages. I was required to make 3 function in the file to perform this tasks. my problem I am having a division problem in the SLG function. My compiler does not require the system ("PAUSE"); command.
OUTPUT
The player's batting average is: 0.347
The player's on-base percentage is: 0.375
The player's slugging percentage is:
(test)AB = 101
(test)Tot Base = 58
0.000
Code:
/* Batting Average Program
file: batavg1CPP.cpp
Glossary of abbreviations:
BA = batting average
PA = plate appearances
H = hits
BB = bases on balls (walks)

The task is to return the number of bits set to true.Here is my code:
Code:
int cardinalityBS(PBitSet _this) {
int s, counter = 0;
for(s = 0; s < 31; s++) {
counter += _this->bits & 1;
_this->bits <<= 1;
}
return counter;
}
[code]....
The code is not working, since whenever I set _this->bits to a number, it returns me the wrong result.

It seems as though my program is working great but I'm having problems with my random number generator. It keeps giving me a return value from the computer of scissors (or 3) for the computers random choice. What can I do?
//Purpose of Program: This program is meant to prompt the user to choose between 4 menu options.
// Each option will be the users choice of rock, paper, or scissors.
// the computer will then randomly generate a number and pit you against the computer.

I have a class called items and stored in a vector as vector<items*> item.now I want to make a function to return the placement # that the item is stored at with a unsigned int. but if I don't find the item is there like a null unsigned int that can be returned.
unsigned int someFunc(vector<items*> item)
{
unsigned int size = item.size();
for (unsigned int i = 0; i < size; ++i)
{
if (item[i]->getItemName() == "sword")
{
return i;
}
}
//i need code here incase the item is not there
}
because the item might not be there and i would like to do a line if(unsigned int) do this code
