C# :: Creating Complex Number Calculator - Convert String To Ints
Sep 18, 2012
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.

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;

I am getting a string from the consle and that all works fine. I'm expecting a string of number, ie 123456.... I store that fine in my string object. I then need to take each individual number, ie 1, and put it in a vector then take the next number, ie 2, and put that in the next element in my vector.
Everything i've found and does eaither takes the entire string and stores it as an int, or takes the ascii representation of the number and stores that. How do I seperate each individual number and store them seperatly. below is a few different variations i've tried that doesn't produce my desired results.
cout<<"Please type the memory memory frames (numbers 0-9) to be used to simulate the input memory "<<endl;
cout<<"Your input: ";
string line="";
cin>>line;
cout<<"
Please wait while your input is processed and validated..."<<endl;
[code].....
the only thing i havn't tried yet is string streams and i don't necessarly like using them. Am i going to have to go that route? will that even work?
EDIT:I forgot to mention that this is being done on linux and then ported to unix.

I've been wondering this, since there is so many things which needs to be taken care of. I created one, but it wasn't precise.

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 );

I want to convert a decimal number to binary and store it in a string so that I can use that binary output for later computation. Here is what I did
Code:
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
void main()
[Code] ....
Now as you can see that all the binary output is in a[] but how do I get it into a string so that I can use something like printf("%s",string) and get the binary output ?

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

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;

I'm having trouble making a .obj loader at present I'm trying to load faces that are defined as follows:
f 1/1/1 2/2/2/ 3/3/3
So far I've separated the the three number groupings into three strings, I've had a few issues with stringstreams and would like a simple solution.

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 new to C programming, I have been given an assignment to create a simple calculator by splitting the program in 3 files. It should have 2 .c files and 1 .h... I went through the internet extensively and could only come up with this.
main.c:
Code:
//Calculator main.c
#include <stdio.h>
#include <conio.h>
#include "Functions.h"
int main() {
float x = 0, y = 0;
int operation;
[Code]...
Functions.c
Code:
#include "Functions.h"
extern float x, y;
float addition (float a, float b) {
return a + b;
[Code]...
Functions.h
Code:
#ifndef FUNCTIONS_H_INCLUDED
#define FUNCTIONS_H_INCLUDED
float Sum(float a, float b);
float difference (float a, float b);
float remainder (float a, float b);
float product (float a, float b);
#endif
When I do a 'cl main.c' on the Developer Command window for VS2013, i get an error that reads :
main.obj
main.obj : error LNK2019: unresolved external symbol _difference referenced in function _main
main.obj : error LNK2019: unresolved external symbol _product referenced in function _main
main.obj : error LNK2019: unresolved external symbol _addition referenced in function _main
main.exe : fatal error LNK1120: 3 unresolved externals

In my calculator, I am trying to make it so that you put enter 1 to add, 2 to subtract, 3 to multiply, and 4 to divide. I am facing the issue of making it so that you must enter a number, however instead of it being any number, it must be 1, 2, 3, or 4, and if it is not any of those numbers, you must re-enter the number. Here is a little snippet of my code:
Code:
printf("Please enter 1 to add, 2 to subtract, 3 to multiply, or 4 to multiply: ");
while (scanf("%d", &input) != 1) {
while (getchar() != '
');
printf("Invalid option. Please try again: ");
[Code] ....
how I can make the loop affect specific numbers.

I'm working on an assignment where the user inputs the center coordinates(x,y) for an circular array of (x,y) points. The program performs some calculations, then outputs the position of each point, based on the diameter and center location.
The issue I'm having is that the number of points is a variable(inputted by the user). How to make the program perform the calculations for a different number of points each time.
Code:
// Bolt position Calculator
// Calculates position of bolts on plate using number of points, hole diameter, and (x,y) coordinate of center
#include<iostream>;
#include<math.h>;
#include<cmath>;
#define PI 3.14159
using namespace std;
int main() {
int n,xn,yn
float D,x,y,A;

I am working on a project which is a fairly simply BAC calculator. I am attempting to grab data from a text file, which contains state abbreviation, maximum BAC before aggravated, and minimum license suspension. The text file looks like
#include <iostream>
#include <fstream>
#include <string>
#include <cmath>
#include <stdio.h>
#include <ctype.h>
#include <iomanip>
#include <algorithm>
#include <cstdlib>
#include <sstream>
using namespace std;
float MALE_RATE = 0.68, FEMALE_RATE = 0.55, LEGAL_LIMIT = 0.08;
//percent of body weight which holds alcohol
[Code] ....
The code I am struggling with is the getline and stringstream which is near the bottom.
The output I am getting is
The maximum BAC before aggrevated DUI in AL is .15
The minimum penalty in AL is 90 day suspension of license
I get that for every state I type. I know it is reading the first line, but something in my code does not allow it to read the other lines

I have a calculator with buttons, and when I click the numbers or operators, it goes to a string array. So;
Press 3
Press +
Press 2
Press =
and my array is str[0]='3' str[1]=.... so on...
And also I have a C code which calculates the string you entered with some algorhytms and gives a double value as a result. So the question is;
How can I send my STR array in C# to my C program? I mean I want to use my C program as a source code. and How to return that double value to my C# program?
For now, I don't want to change my C codes into C# codes. I want it to keep as is. Just use it as a source code. Is that possible?

heres the function:
string ToString ( const char * format, ... )
{
char buffer[256];
[Code]....
these function do the same of the sprintf() function. but instead we use a variable for add the result, i want to return the result. when i use it:
string f;
f=ToString("hello world");
gives me several errors:
"error: crosses initialization of 'std::string f'"
"error: jump to case label [-fpermissive]"
