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++ :: Float And Double Data Types - Cannot Store Infinite Numbers
Sep 6, 2013I was working on float and double data types and to see the results i wrote this program:
#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;
int main() {
ofstream outputF("output.txt");
double a = 1;
double outcome;
[Code] ....
Well I understand the part it cannot store infinite numbers. but if you take a look at the output for example (since it is too long i just added some of the outputs)
//---------------------
for the value of : 001
1
//---------------------
for the value of : 002
0.5
//---------------------
for the value of : 003
0.3333333333333333148
[Code] ....
if you look carefully at the value "5" and "10" results. it is awkwardly abnormal. which is something i couldnt understand. also it is the same with value "20", "25", "40", "50" and so on.
C :: Reading Infinite String?
Sep 24, 2013I have made a program that can take an infinite string:
Code:

But there is some problem in it, like its printing extra characters after string. reading infinite characters in a string
C :: Finding Written Numbers In A String And Converting Them To Decimal Numbers
Jun 20, 2013User enters sentence "The Smiths have two daughters, three sons, two cats and one dog." (The numbers may change depending on what the user chooses to enter. He told us the range would be from zero to nine.) and we have to convert the written numbers within the sentence into actual decimal numbers and print out the new sentence. Ex. The Smiths have 2 daughters, 3 sons...etc.
I have written the following bit of code which reads the string and finds all the "written numbers" but I am not sure how to proceed from there. I am stuck on how to print out the new sentence with the converted numbers as my professor mentioned something about creating the new string using dynamic memory allocation.
Code:
#include <stdio.h>#include <string.h>
int main () {
char A[100];
int length = 0;
int i;

C++ :: Not Getting Right Value For Addition
Jan 17, 2013Code:
#include<iostream.h>

class vector {
float x_comp1,y_comp1,z_comp1,x_comp2,y_comp2,z_comp2;
float add_x,add_y,add_z;

Now the problem is that when i run the program, i get correct value of the two vectors, but i am not getting the right value for the addition...it might be the x_comp1 and so on are not getting those values even i am assigning them..

C/C++ :: Making Addition Loop?
Nov 19, 2014What my ultimate goal here is to make a program that asks the user how many numbers they would like to add followed by asking the user what numbers they want to add. I want the amount of numbers they can add to be infinite and have the loop continue adding the numbers until it reaches the final number. I just need to know how to do this.
Here's my code:
#include <iostream>
#include <string>
using namespace std;
int main() {
//variables
int amount;
float num;
float sum;

C++ :: Vector Addition With Magnitude And Direction

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++ :: Overloading Addition And Comparing Expressions In A While Loop
Apr 28, 2015I have two questions that are related to each other. The first one is about overloading the addition operator.
I have defined a struct as the following:
Code:
#include <iostream>
#include <string>
struct Sales_data {
[Code] ....
I then overloaded the I/O operators so I could print to the screen information related Sales_data.
Code:
// overload ostream in order for cout to work
std::ostream& operator << (std::ostream & out,
const Sales_data & cSales_data) {
out << cSales_data.bookNo << ", " << cSales_data.units_sold << ", "
[Code] ....
My first issue is with overloading the addition operator. Everyone works correctly except for std::cout << item << std:endl; will no not output the ISBN number only the units_sold and revenue when added together.
Code:
// addition operator rules
Sales_data Sales_data::operator + (const Sales_data & data2) {
units_sold += data2.units_sold;
revenue += data2.revenue;
return *this;
}
Now here is the code in its entirety
Code:
#include <iostream>
#include <string>
// Sales_data structure
struct Sales_data {
std:: string bookNo;
unsigned units_sold = 0;
[code] .....
After total = total + item;, I would like to print the total for this particular ISBN. However, I only get: blank, total units, total revenue where blank is where the ISBN would go but doesn't print after addition. My second question has to do with comparing the ISBN's of the books entered during the while loop. I would like to do something like
Code:
if (item_i.bookNo == item_i+1.bookNo) {
total = total + item;
} else {
std::cerr << "Books entered must have the same ISBNs" << std::endl;
}
Unfortunately, I cannot figure out how to set up a comparison of the bookNos. If I used #include <casset> in the overload + rule, it will immediately exit since I have no way to compare the ISBNs.
C++ :: Create Function That Performs Addition Of X Days At A Time?
Jan 26, 2012I need to create a function that performs the addition of x days at a time, taking two integer values, the first being a date (yyyymmdd format) and a number of days to add / subtract that date.

C++ :: User Input Data About Percentages To Calculate Final Grade - Addition Error?
Sep 15, 2014I am trying to code a program that takes in user inputted data about percentages and using it to later on calculate a final grade. 4 percents are inputted, for Assignments, Midterm1, Midterm2, and Finals. If the percents dont add up to 1 (i tell the user to enter the decimal value) I set up and if statement to catch it and end the program. Except that if i type in
Assignments = .3
Midterm1 = .3
Midterm2 = .3
Finals = .1
the program doesn't recognize that they add up to 1. Heres the relevant portion of my code [URL] ....
Here's some examples of how it works [URL] ....
And heres what i dont understand [URL] ....
Why is it saying .3 + .3 + .3 + .1 != 1 when .1 + .3 + .3 + .3 == 1?
C :: How To Get Rid Of Infinite Loop

C :: Why Keep Getting Infinite Loops
May 30, 2014See code below:

Using gdb, I noticed that the variable j keep going back to initial value after the interior for loop condition returns false. Why doesn't this for loop terminate right away?
C/C++ :: Infinite Looping For Map?
Jan 13, 2015I have been trying to get this piece of code to work but it seems to be running infinitely. What i'm trying to do is that whenever the iterator points to the map element, I check whether the element is 1 or 0. If it is 0, *do something*. But if it isn't, it should not do anything and proceed to the next element in the map.
//infinite loop - not working!
for (MapType::iterator p = pwCounter.begin(); p != pwCounter.end(); ++p) {
if (p->second.second != 1) {

C/C++ :: Infinite Loop Of Asterisks Or Nothing At All?
Jan 27, 2015So I have to create a program which will print, among other things, a rectangle made of asterisks. The rectangle has to follow this general format:
*****
* *
*****
but with the width and length of the rectangle being set by the user. I've tried every way I can think of to work this out, but I can't seem to get anything to work. The main errors I'm getting are either an infinite loop of asterisks filling my screen or nothing at all, depending on whether I use an && comparison or ||. A screenshot of my code is included below.
