C# :: Program Keeps Adding 1 To Result?
Oct 21, 2014
I am creating a program that allows the user to enter the number of days worked and calculates the amount of money gained by doubling the amount from the previous day, starting with .01 cents. The program works fine except for in day 3, the program adds .01 along with doubling the amount from day 2. Also I must use a List Box.
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;

So I have this program to calculate the types of meat, I have fixed the system errors but the actual program when I run it comes up with <null>
Code:
#include <stdio.h>
#include <stdlib.h>
#define beef 1 /* multiplication factor of beef*/
#define chicken 1.5 /*factor of chicken*/

The program adds 2 matrices that are 3x3 using arrays and then stores them into another matrix (array) and then it's edited to show a diagonal line of "0" through it, btw I'm pretty new to programming....
insert
Code:
#include <iostream>
using namespace std;
int main() {
int x[3][3],y[3][3],c[3][3],i,j;
cout<<"Enter your numbers"<<endl;
[Code] .....
It works almost just fine lol, Except that the first portion of the diagonal line does not become zero and instead displays the normal addition result.....

I wrote a program that should check if phrase is in file and output the result.
File:
//////////////

Why my program doesn't cout?
#include <cstdlib>
#include <cstdio>
#include <iostream>
#include <fstream>
using namespace std;
string checkData (char Input[], char dataB [], int nMAX){

I have this simple program below:
Code:
#include <stdio.h>
#include <limits.h>
unsigned int rightrot(unsigned int x, unsigned int n) {
/* calculate number of bits in type */
size_t s = sizeof(x) * CHAR_BIT;
[Code] ....
The result it prints is 2684356604 on my 32-bit computer. The result I expect is as follows:
0xFF94 is 0000000000000000 1111111110010100 in binary.
Shift it right by 5:
0000000000000000 0000011111111100
Then take that result in shift it right by 27 (s is 32 and p is 5, so the difference is 27):
1111111110000000 0000000000000000
Now we use bitwise or:
0000000000000000 0000011111111100 | 1111111110000000 0000000000000000 = 1111111110000000 0000011111111100
That in decimal is 4286580732. So how does it come up with 2684356604?

I'd like to add a 'command' to my C program. For example if someone types 'get out' it closes the shell and quits. I want the 'get out' command to work like 'exit'. How do I write a code like this
Code:
char entry[15];
scanf("%[^
]", &entry);
if (entry = "get out")
do "exit";

To add my program into the context menu (when the user right click on excel file). I used the following code:
Code:
public static bool AddContextMenuItem(string Extension, string MenuName, string MenuDescription, string MenuCommand)
{
bool ret = false;
RegistryKey rkey = Registry.ClassesRoot.OpenSubKey(Extension);
if (rkey != null)
{
string extstring = rkey.GetValue("").ToString();
[Code] .....
I used the following function to retrieve the excel file path has been rightclick choose to load the program:
Code:
public static void OpenExcelFileWithEasyForm(string filePath)
{
try
{
string excelFilePath = Path.Combine(Path.GetDirectoryName(filePath), string.Format("{0} (EasyForm){1}", Path.GetFileNameWithoutExtension(filePath), Path.GetExtension(filePath)));
[Code] .....
But I still do not load the excel file into my program by selecting the program from ContextMenu (right click on excel file and choose program). Although if select the path to excel file from the program, the data from excel file is loaded into the program.
I'm still missing something at function OpenExcelFileWithEasyForm(). How to complete this function to load the excel file into my program when selecting programs in ContextMenu.

I was trying 2 write a program that would calculate the sum notation of 1/(i^2) with the starting number to be 1 and goes up to the nth term. For instance if the user inputed 3 then the sum would look like 1+1/4+1/9. I somehow made a code but it gets weird numbers which some include negative numbers... when I input a number that is above 5.
#include <stdio.h>
#include <math.h>
int main(int argc, const char * argv[]) {
int n;
register int i=1;
float b;//For part 1
[Code] ....
For some reason I can't edit printf("%f",/>/>; when I post it as the topic so ignore that part cuz Ik its supposed to be written as printf("%f",/>;

The program that I have written below is working. It calculates a number of payroll type variables and most recently the net pay average (All this is working 100%).
My problem is that I need to add first and last employee names to the program but every time I do this I end up ruining the working program. I've successfully added first and last names to similar programs in the past(ones that make use of an array and while loop) but never to a program that uses functions (I always have problems doing this).
My question is what codes do I use to add a first and last name variable and where do I put those codes within my program so it runs/displays correctly.
I think the coding must be similar to what I've used in the past charr and of course firstname[i] and lastname[i] lines.
Current Input File:
16454025.00
89324020.00
71044012.50
28164026.00
53874021.00
67804013.50
56414011.25
90006025.00
90015020.00
90025523.00
Ideal input file (would include names) Example.
1645 Bob Smith 40 25.00
Syntax:
#include <iostream>
#include <iomanip>
#include<fstream>
using namespace std;
//function prototypes
int readalldata(long int[], int[], float[], const int);
void findovertimehours(int[], int[], int);

I am making a multiple quiz program. So everything is working fine, except for the part where i'm trying to add a highscore for each user which is being stored in a binary file. I have added a sample of the program containing the error. This isn't the actual program, which is very long.
class user { //The collection of all info pertaining to the users
char user_id[50];

int hscore1;
user() {

I'm trying to understand the pass by value-result. The code I have came up with so far only does by value and by reference, which I understand. The value-result is what has me stumped, and honestly I am unsure how to write the function for it. Here's my code so far...
#include <iostream>
using namespace std;
// Function prototypes.
void swapByValue(int, int, int);
void swapByRef(int&, int&, int&);

I keep getting an undesired value in this code. I've tried several methods, but none are giving me the correct answer. The out put is always zero, when in this case it should be 10!!
Here's the object structure:
template<class T, class _b>
struct quantity {
private: T value;
public:
explicit quantity(T val): value(val) {};
T getValue() { return value; };
[Code] .....
Here's the operation:
int main() {
quantity<int, bool> m(20);
quantity<float, bool> m_f(10);
quantity<double, bool> m_d(NULL);
m_d = m_f;
[Code] .....
Why does it seem that the assignment operator is the harder operator to overload? Maybe it's just my luck, but I seem to always run into issues whenever I work with it. I hardly ever experience errors when overloading any of the other operators.

//*Delcare function prototype*
int ConvertToCentimeters (double, double );
//declare exception class*

how to use the result of an if statement in my program. I'm writing a program for a knockout tournament, so i want to extract the winner of each match to carry forward in the code for use in the next round. I've tried assigning another variable (#define r1w1) and saying that the variable = cName[0] or cName[1] in the if statements like this: (i did this because i thought i could then use r1w1 later in the code)
if(scorea1 > scoreb1) {
printf("
");
printf("WINNER OF ROUND 1 MATCH 1 IS %s
", cName[0]);
cName[0] = r1w1
