C++ :: Program Compiles Successfully But Calculations Give Wrong Answer
Feb 11, 2013
I'm using MSVC++ and it builds sucessfully but somewhere something is obviously messed it. Once i try to debug it just shows weird numbers.
int k=0; //could this be the problem??? since 0 would be over writing any given value. but if i leave int k; it showsa warning and MSVC would count that as an error
#include "stdafx.h" //Header file section
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
//structure declaration
struct menuitemtype

//#include "stdafx.h"
#include<iostream>
#include<cmath>
using namespace std;
//class declaration
class dayType{
public: int presday;
[Code] ....
So everything works perfectly, well not everything lol. Code compiles successfully without any errors but previous day does not calculate. In a sense that when it asks for number of previous days it returns a blank statement.
For example: Previous number day is: shows nothing

I have two unassigned variables A,B . My program goes as follows
#include <iostream>
#include <string>
#include <cmath>
#include <stdlib.h>
using namespace std;
bool die (const string & msg);
[Code] ....
This a program that makes a calculator in which this is a small portion of it, all the exponent numbers work exceptfor anything ending in 5.
Examples go as follow 2^3=8, 3^2=9, 5^2=24
I want to why this happens, is it because they are unassigned variables?

So I'm writing a program that will read a text file and it will do certain "functions" the text file will be like a game, and the program will be able to run many different games. The problem i'm having is in one of the "functions" i believe it's the one meant to get a correct choice from a file and a user input and put them into strings, it gets the wrong input. I know this because i tested both strings the "function" writes too. it gets the correct file answer but the user input is always "c" for some reason.
#include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <stdlib.h>
using namespace std;
int progfiles() {
[Code] ....
This is the code, most likely the section that is surrounded with "///" contains the problematic "functions." This is the command Line output...investigate why they're dieing or continue on your journey?(i-investigate/c-continue) got input and answer
i
c
i
Press any key to continue . . .
The got input and answer are tests to make sure it got both, the first 'i' is my input, the 'c' is what it says my input is, and the 'i' is the correct answer from the file. this is the part of the file that the program reads to get that output
"1 Do you want to go investigate why they're dieing or continue on your journey?(i-investigate/c-continue) 2 8 i 7 3 4 You continue on picking up speed to get to the egg first.. and.. Oh No, You accidentally bumped into the walls! 2 12 5 1 You go over, and as you realize the walls are acidic and that's why the other sperm are dieing.. 2 6"

I need to write a program that will give me multiple calculation results.
#include <iostream>
using namespace std;
int main () {
int x = 8;
int y = 7;
[Code] ....
It only calculates the last two numbers: 1 and 0, so therefor it gives me 1.
But i need to calculate x and y each time they are smaller(incremented) by one digit.
Please note that the int calculation formula needs to stay.

i have only recently got into programming. i have this homework assignment that is frying my brains, the program needs to take a number from the user and give the 'reduced' sum. for example: if the user enters 888 then the sum should be: 6. it takes the number and adds its digits im just looking for a direction to where my problem is
#include "iostream.h"
int reduction (int number) {
return number/10+number%10;
}
int main() {
int number,loopcount;
cout<< "please enter a number"<<endl;
cin>>number;

I'm writing a program that shows check fees for different amounts of checks. My other fees are showing up right but the .10 cents is not. It's showing up as .08 cents per check when I run the program.
Oh yeah the + 10 is for a $10 fee
Code:
else if (checks < 20 || checks >= 0) {
fee = .10 * checks + 10;
cout<< "Bank service charge for the month is $ " << setprecision(4) << endl;
}

In my MainWindow I have a UserControl called CamAccessLevel1. This will be one of a few different UserControls which will have more and more functionality to a device as the Level goes up.
Each of those functionalities are themselves a UserControl, so that I don't have to keep remaking them for each different "Level" that I make.
So... I have a UserControl in a UserControl in my Mainwindow. My first goal is to have a button in one of those sections send an event back to the MainWindow to close the application. This sections is called "ProgramControl", as it has functions that relate to the program itself.
I can't seem to set a datacontext within another datacontext -> There is an error in UIViewModel below...
Note that I have replaced my company name with [snip]
In my Mainwindow.xaml
<views:CamAccessLevel1 x:Name="UserInterface"/>
Mainwindow.xaml.cs
public partial class MainWindow : Window {
#region MyModel

So I'm making my first program w/ C++ and its a game guessing game. I've learned how to use booleans, chars, strings, if/else, loops, and input. Anything past that I dont know. I've gotten my game to work properly except for the fact that when you guess incorrectly, the program closes. I want the program to go to the beginning of the program again so the user can restart. So far i've gotten the loop to beginning thing to work but not well. It'll only repeat twice before closing again and it'll say the user got the wrong answer even if it was correct. Here's my code
#include <iostream>
#include <string>
#include <random>
#include<ctime>
using namespace std;
int game(){
string playerName;
int guess;

I am writing a program to tell how long it will take for a loan to be paid off supposing the desired loan is 100,000, the annual percentage rate is 6, and the monthly payment is 1,000. What happens is after I run the program, I get the output of "-24.60" after the last month is paid off. I'm trying to get it to where the last monthly payment is only enough to make the loan 0. Then I want the program to end.

Okay so I thought I had this assignment completed properly last week. Last night I found a bug while playing the game.why won't the game end when the player guesses the correct number? The game allows you to finish using the max number of guesses even though you already guessed the correct number.
Code:
#define _CRT_SECURE_NO_DEPRECATE
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#define MAXGUESSES 6
#define MAXGAMES 20
#define MAXNUMBER 100
}

I have a text file that contains values as follows:
2013 05 27 15 52 02.049824 231.401 0.022 49.738
2013 05 27 15 52 02.668822 229.814 0.019 49.738
2013 05 27 15 52 03.283705 228.528 2.599 49.726
2013 05 27 15 52 03.898469 230.140 2.576 49.751
Column1=date, Column2=Month, Column3=Day, Column4=Hour, Column5=Minute, Column6=Seconds, Column7=Voltage(Vrms), Column8=Current(Irms), Column9=Frequency(Hz).
I have to develop a program that will analyse these time-sampled voltage and current measurements over 24 hours and find the total energy used, mean and peak power consumption and Energy used over each hour of the 24 hour period.
How do I go about doing this? I also have to use at least one integration method. The file data contains over 50 thousand lines in the format mentioned above.

I tried to create a multiple choice list and I want to assign the value of the answer option chosen by the user so I can use it later on in the code. Later on in the code i've asked how many people (p) want a drink and multiplied it by the chosen size to calculate the price c = p * n where c is cost, n is price and p is number o of people At the bottom i tried to assign parameters where depending on what option the user has chosen n will be assigned to the chosen value...
{
printf("SELECT TYPE OF PAINT:"); /*multiple choice of paint */
printf("1. Large ");
