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/C++ :: Matrix Class - Addition / Subtraction
Jul 7, 2014I'm working on a matrix class and I've hit a few snags. Here's what I've got so far:
Matrix.h
#include <iostream>
#include <conio.h>
using namespace std;
class Matrix {
private:
int matrix[50][50];
[Code] ....
Where I have questions is in implementing the addition and subtraction bits into the class itself. I understand that I'm going to have to do a copy operation (this from reading in C++ Primer Plus 5th Edition). Right now I'm just after adding/subtracting as the rest will be variations on the same theme.
So, here it goes:
As I understand the problem, I need to pass my two matrices as arguments to an addition function. This is going to involve having to copy the values of the two existing matrices into temporary matrices within the addition function, then I'll add them, and store them in a new matrix which will be my return value. So...something like this:
int Matrix::matrixAdd(int R, int C, const Matrix & matrix1, const Matrix & matrix2) {
int sum;
Matrix matrix;
for (int i = 0; i < R; i++)
[Code] ....
I do end up with errors there...C2240, and C2662. Again, I'm new to working through this, but that's what I've got. My idea is that I'm passing the maximum size of the array as defined by the user, in this case a 2x2 array, it'll cycle through and add up to that imposed limit...I went 2x2 because it's small enough that testing doesn't drive me up a wall.
C :: Addition And Subtraction Calculator That Takes Input?
Feb 23, 2013I'm writing an addition and subtraction calculator that takes input as: 5+6-3+2. You should be able to add or sub as many numbers as you want. I want the while loop to stop when the user hits enter. I put the getchar() function to catch the and break the loop but it is also swallowing the '-' sign, which I want to use to subtract and is instead adding the numbers with "sum+=number". How can I get around that?
Code:
#include <stdio.h>
int main(int argc, char *argv[]){
int number, sum = 0;

C++ :: Subtraction Of Two Integers?
Apr 18, 2014I am working on an assignment where I have to subtract two very large integers. How can I write it's code provided that I have both numbers in a character array with each index holding a fraction of the original number. Like if I have a number 123456789 in an array then
arr[0]='1';
arr[1]='2';
arr[2]='3';
arr[3]='4';
and so on. n
nNw if i have to subtract this number from an other number, how can I do that?

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++ :: Random Integers (numbers)
Oct 17, 2014I'm trying to make a C++ program that generate 6 random numbers ( from 100,000 to 999,999 ), okay, so I wrote a few lines..
Code:
srand(time(0));
for (int i = 0; i < 5; i++)
{
std::cout << 100000 + (rand() % 999999) << std::endl;
}
The problem is, that it generates numbers like this:
117,207
123,303
131,083
... etc etc..
They're all starts with 100K, i want them to be an actual random..
C++ :: Validating That There Are No Integers Only Numbers
May 20, 2013I am working on a program where the person enters their name and their gross pay. I had to validate that the gross was a number and contained no letters.
I also have to validate the persons name to see if it contains any numbers. The book I am using has an example with only an if statement that says if it is correct or incorrect. I was trying to use <cctype> and toalpha
I just was wondering if there was a way to put it into a while loop or how i would have it ask the user to input their name again. When i tried it just blew up.
Also in the book they use const int SIZE= 8, but I don't want to put a size on the name if I don't have to.
C++ :: From Array Of Integers Take Numbers That Occur Only Once
Jan 14, 2013I am trying to find a way to do something like this:
input: 3 4 7 4 3 3 7
output: 3 4 7
So what I am trying to do is from an array of integers to take numbers that occur only once. If 3 is in that away I am trying to input it in a different array only once.
input: 8 3 2 9 8 9 2
output: 2 3 8 9
I cannot find a way to solve this, and I have been trying to solve it for a long time.
C++ :: Take Numbers And Add One By One As Integers In Linked List
Aug 21, 2013Let's say that in a txt file named hot.txt, I have this:
12,23,32
And with ifstream I want to take those number, adding one by one as integers in a linked list.
ifstream myList;
char* p= new char;
cin>>p;
myList.open(p);
if(myList.is_open()) {
char* x =new char;
[Code] ....
I know this part is quite wrong :
myList.get(x,256,','); // dafaq
int num=atoi(x);
list->addOrdered(num);
What I wanted to do is to stop before each comma and take that character and store it in the linked list and continue until the end of the file, but I couldnt.
C++ :: Convert Numbers To Integers - Parsing EOF
Oct 26, 2012Here`s the text:
You have to expect the following input : an arbitrary amount of lines, each line consists of 5 int32 numbers. The full input will be terminated by an EOF.
E.g.:
1 2 3 4 5
6 7 8 9 0
...
You`re then supposed to convert the numbers to integers and do some calculations. I would know how to parse a single line of 5 numbers via scanf(). That`s easy, and that`s exactly what they did in class.
But how do i go about splitting the lines? What about the EOF? Even if could hack something together, by using errno or something, it would be way beyond what they are doing atm. The input is received via user input, ie stdin.
C :: How To Take String Of Numbers And Turn It Into Array Of Integers
Mar 2, 2014I know strings are essentially just arrays of characters, so what would be the easiest way to take each individual digit and put it into a separate space in an array?
ex.) *str = "90210"
array[0] = 9
array[1] = 0
array[2] = 2
array[3] = 1
array[4] = 0
All my attempts at achieving this just result in an array full of garbage numbers. What I've done is
Code:
int *array;
array = malloc(sizeof(int)*(strlen(str));
for(i=0; i<strlen(str); i++) {
array[i] = str[i]
}
also, I should mention that the string will be defined in main, and its converted into an array in a separate function.
C :: Function For Raising Numbers To Positive Integers
Sep 18, 2013Write a function that raises an integer to a positive integer power. Call the function x_to_the_n taking two integer arguments x and n. Have the function return a long int, which represents the results of calculating x^n.Here's my code:
Code:
#include <stdio.h>
long int x_to_the_n(int x, int n)
{
int i;
long int acc = 1;
for(i = 1; i <= n; ++i)
acc *= x;
}
[code]...
It compiles OK, but when I run it the program stops after entering the number (x) and power (n).
C :: Turning String Of Numbers Into Array Of Individual Integers
Mar 2, 2014In my program, I am fed a string that contains integers such as Code: *str = "45678" and my program is simply supposed to read the number in and store each given number in a separate spot in an integer array. So basically, when my program has finished running it should be stored like:
Code:
arr[0] = 4
arr[1] = 5
arr[2] = 6
arr[3] = 7
arr[4] = 8
The way I have been attempting to do this was just copying it to the array like so:
Code:
arr = malloc(sizeof(int) *(strlen(str));
for (i=0; i<strlen(str); i++) {
a->digits[i] = str[i];
}
however, this just seems to return an impossibly high garbage value when I do. I'm assuming the way I'm trying to store it is 'illegal', but I cant seem to find online a proper way to do it.

View 6 Replies View RelatedC++ :: Read Two Positive Integers That Are 20 Or Fewer Digits In Length And Output Sum Of Two Numbers
Apr 30, 2013so basically my project goes like this:
Write a C++ program that reads in two positive integers that are 20 or fewer digits in length and outputs the sum of the two numbers.
Your program will read the digits as values of type char so that the number 1234 is read as four characters '1', '2', '3' and '4'. After they are read into the program, the characters are changed to values of type int. The digits will be read into a partially filled array and you might find it useful to reverse the order of the elements in the array after array is filled with data from the keyboard.
Your program will perform the addition by implementing the usual pencil and paper addition algorithm. The result of the addition is stored in an array of size 20 and the result is written to screen. if the result of the addition is an integer with more than maximum number of digits(that is more than 20 digits) then your program should issue a message saying that it has encountered "integer overflow".
You should be able to change the maximum length of the integers by changing only one globally defined constant. Include the loop that allows the user to continue to do more additions until the user says the program should end. What I have so far is
#include <iostream>
#include <cstdlib>
using namespace std;
void reverseArr(int a[], int liu);
void addLargeInt(int a1[], int liu1, int a2[], int liu2, int sum[], int& liu_sum);
int main() {
cin.get(next);
