What 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;
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.
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.
I have a program that makes change from an amount. It works fine, but the output is the correct output looped over and over. I have tried everything, but it still doesn't work. For example, a amount of 98 should print
#include<iostream.h> #include<conio.h> class vector { float x_comp1,y_comp1,z_comp1,x_comp2,y_comp2,z_comp2; float add_x,add_y,add_z;
[code]....
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..
1)What should be the best variable for adding two 6-digit hexadecimal,such as 0034AD,0057EA? I would like to use array of character but it seems hard to handle.
I need addition array1 array2 in new array before I make this program but the values of array1 and array2 there are in code c# that is worked without problem.
But now i need the user enter the values of arrays, i make that but i failed in addition array1 and array2
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace MyArray {
i new to c++ programming. i have a program due soon in vector addition. i am to design should be able to add vectors with certain magnitude and direction and give its resultant magnitude and direction (i know how to do this mathematically but programming is not working. the user should be able to select how many vector he/she wants (i don't know how to do this, so i added 3 vectors). here's my work - i did this purely algebraically. it's still incomplete but it compiles. my "if else" statement also doesn't respond correctly.
#include <iostream> #include <string> #include <vector> #define PI 3.14159 #include <math.h> std::vector<int> v; // declares a vector of integers using namespace std;
I'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.
Below 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.
I'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;
I 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.
How can I perform validation if the entire amount received is a valid date and how can I add x days of that date?
Below is a program that generates random Addition for Subtraction problems depending on the user's choice. The user is prompted to input an answer and then it keeps your score. If you want to quit you just press zero.
Code: #include <iostream> #include <stdio.h> #include <stdlib.h> #include <time.h> #include <iomanip> #include <string> using namespace std; int menu(); bool addition(int &reward); // function to return truth values
I 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
Here's my game, what do I need to learn to make a basic GUI? (Easiest way possible for now).
--NOTE, the code was a bit too long for me to post. I can add it if it is necessary. Basically all I want are 4 buttons on the main screen, one that says "Arena," "Store," "Stats," and "Exit."
There will of course be sub menus to each option, but we will get to that later.
I have project that is on c++. it runs fine. i want to use it in my C# application as a dll. i have created its dll and but firing exception of "interprocess communication".
Is this a doable task that creating dll of an exe project and using it in C# application?
I am trying to get this to work without arrays. At the moment all I am trying to do is allow it so that when the user presses 1 the board prints with 1 replaced by X, tell me where am i going wrong. I know its not finished.
#include <stdio.h> #include <stdbool.h> char a = '1'; char b = '2'; char c = '3';
We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.
I have tried to submit this topic before but i didn't submit my whole code and it was removed. So here it is. All I am trying to do is load form2 from form1 then back to form1 from form2 for a certain number of times the get out of the loop. I am new to C-Sharp and it seems as though I cant seem to figure out a way to do this.
Here is form1 and form2 code. I have commented out a few things I have tried.
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data;
So basically I have to write a C program that, when opening the html file in a browser, looks essentially like this: (Size, position, color of the shapes doesn't matter so long as I have one of each shape and the box surrounding them. Words up top dont matter either.)
This is what I have so far: Code: #include <stdio.h> #include <stdlib.h> #define FILENAME ("A4P1.html") [code]....
Anyways i can get the individual shapes, but I don't know how to get all the shapes to appear at once..
i have an assignment where i have to draw a teapot using triangles, and are struggling with the part where i have to color it. Here is an link to the assignment URl....
I have managed to draw the teapot and translated it onto the screen. the part i need support with is making a bounding box for the triangle and coloring it.
