I wrote a code to ascend any three integers. Problem is the code does not output the numbers in ascending order all the time. What am I doing wrong? here is my code :
// This program will prompt user to enter any three integers and then out integers in ascending order
#include <iostream>
#include <cmath>
using namespace std;
int main() {
int num1,num2,num3;
cout << "Enter the first number: " << endl;

I have tried writing a code and come across an issue where I'm not getting the desired result. It is to design a program that tells whether gas emissions from a car are too high, or permissible. The instructions are to design a code where there are four possible choices of pollutant, whether the emitted pollutant ratio is greater or less then a certain value, and the mileage on the car. All of these are supposed to determine whether the emissions are permissible or not, which would be displayed with printf. (The actual conditions of the assignment are described perfectly by the code below, so I didn't think it would be necessary to write it out. The problem is that I'm getting a logical error.) Here's the code:
Code:
#include <stdio.h>
int main() {
int poln, odr;
double gpm;
printf ("(1) Carbon Monoxide
[Code] ....
My error is that the program will proceed with the first four if/else statements, but once the 'poln' value changes to something other then one, it will not display the expected quotation.
In the below program, when we have 4 consecutive spaces, the following comparison will not be equal: (x / tabstop != (x + spaces) / tabstop). If we have, let's say, only 2 consecutive spaces, then the comparison will be equal. So we know to print a tab with 4 consecutive spaces and not print a tab otherwise. How do we know this kind of division comparison would work in every case?
#include <stdio.h>
#define TABSTOP 4
int main(void) {
size_t spaces = 0;
int ch;
size_t x = 0; /* position in the line */
size_t tabstop = TABSTOP; /* get this from the command-line

Here is a simple drinks machine programm. It basically consists in the user selecting a drink that it's presented, if the user selects correctly the number representing a certain drink, the machine shows the user what was the drink he selected, after his choise the machine asks for money insertion, if the user inserts the incorrect amount of money, the machine shows an error saying that user need to insert the correct amount of money.
My problem is that, if the user selects a different number other than those presentend, the machine displays an error saying that he needs to choose a valid drink, but i can't find a way to reprompt the user again after the error has been displayed. here's the code.
// ***Drinkins Machine*** by Roxmate
#include <iostream>
#include <cstdlib>
using namespace std;
int main() {
// initializes the variables coca, fanta, iced and drink to be used in switch function,so that the user can choose what drink he wants.

I'm trying to write a piece of code that calculates the difference in days between two manually input dates. The part of my code that's causing problems is:
xxx
When running the code and prompted to enter the date, if I input for example 31/12/2014, it'll be rejected and send me back to the beginning of the loop. Any date with 31 days involving months 1, 3, 5, 7, 8, 10 or 12 causes this problem. All other valid dates however work perfectly fine (e.g. 30/4/2014).
Something possibly worth mentioning is that, when I take out all other conditions from the loop, i.e.
xxx
it works fine (31/12/2014 is accepted), but of course I need all of the other conditions in there too.
I am trying to use enumeration types in my conditions to make a simple program that calculates area of a square or circle depending on users choice then updates the total area and outputs the total area.
The program builds fine. But it ignores all of my loop conditions and i'm not sure why.

I have a seat allocation algorithm for an airplane 30 x 6 seats. The plane is 'split' front (1 - 15) and back (16 -30), right (A,B,C) and left (D,E,F). I am placing passengers in window seats front right centre (15A) first then back left centre (16F) followed by (15F) followed by (16A). This will continue for single passengers middle seats then aisle.
Another part of the algorithm is to ensure parties >2 or <=6 to sit together in an empty row, if not possible the party will be split as to not have a person in the party sitting alone firstly. i.e. 6 is 3 + 3 or 2 + 2 + 2 or 4 + 2 or 3 + 2 + 1 or 4 + 1 + 1 or 3 + 1 + 1 + 1 and so.
I have got it working for one person but seating two people is a bit more difficult. I am trying to get 15A,15B then 16E,16F then 16A,16B then 15E,15F then 16C 16D and 15C 15D.
This code only allocates passengers 15 A 15B then 15C 15D then 15E 15F
//seat allocation for two people
public bool[,] seatTwoPerson(bool[,] seatArray, int startCol, int endCol, int directionX, int startRow, int endRow, int directionY)
{ //loop through seatArray section determined by parameters
//for (int col = startCol; directionX < 0 ? col >= endCol : col < endCol; col += directionX)

I'm working on a project, and can't seem to get the project to get the triangle variable to increase when the conditions are met. I need this number to be accurate so I can work out the probability.
Experiments that are either too expensive or too dangerous to perform are often simulated on a computer when the computer is able to provide a good representation of the experiment. Find out how to call the random-number generator (usually a function returning a floating point value in the range 0 to 1) for your C++ system. (Look up the functions rand and srand in the library cstdlib on the website cplusplus.com). Write a program that uses the random-number generator to simulate the dropping of glass rods that break into three pieces.
The purpose of the experiment is to estimate the probability that the lengths of the three pieces are such that they might form the sides of a triangle. For the purposes of this experiment, you may assume that the glass rod always breaks into three pieces. If you use the line segment 0 to 1 (on the real number line) as a mathematical model of the glass rod, a random-number generator (function) can be used to generate two numbers between 0 and 1 representing the coordinates of the breaks. The triangle inequality (the sum of the lengths of two sides of a triangle are always greater than the length of the third side) may be used to test the length of each piece against the lengths of the other two pieces.
To estimate the probability that the pieces of the rod form a triangle, you'll need to repeat the experiment many times and count the number of times a triangle can be formed from the pieces. The probability estimate is the number of successes divided by the total number of rods dropped. Your program should prompt the user for the number of rods to drop and allow the experiment to be repeated. Use a sentinel value of 21 to hale execution of the program.

I'm pretty much newbie in creating a successful GUI in C++. Although, i managed to create 4 buttons that should show a certain form. Lets say, Form1 is my main form, therefore - Button 1 will open Form2, and Button 2 will open Form3..... But the conditions is - If there is a form that is already open, clicking again on the Button that should open it, will Close it, but all the forms (form1,2,3,4,5) can be enabled together.
Also, a very important note is that whenever i close a form, in any way of closing it (Not the main form) It will "save" the changes i made (Such as ticking checkboxes and so..) and won't reopen it, it will just use "Visible" i guess ?
Notes :
If i use Form2 ^form2show = gcnew Form2;
and then Form2->Show();
I will be able to simply ATTACK the button and open Billions of form2 ^_^
Although, when i use Form2->ShowDialog();
It won't let me open the form3,4,5.
Which isn't so bad, but when i exit from the form2, it won't save my changes (Such as checkboxes..)
My random number generator isn't working properly. It seems to be ignoring my conditions when it compiles and I enter the input. The program is supposed to accomplish the following.
1. Let the user input how many digits he or she would like to have in the random numbers.
2. Let the user type in how many of the numbers that he or she wants.
3. It will then generate the numbers.
4. It will display the minimum or maximum number it can be with the number of digits the user entered. And display the number of numbers that the user wanted. It also is supposed to check and output only up to the max of that digit range.
so if someone entered they wanted a digit of 1(1-9) but said they wanted 300 numbers it would only output 9
Example:
the user says that she would like 3 digits to be in the numbers generated. So it will output numbers between 100 and 999. then the user says that they would like only 3 random numbers. So it will output three random numbers in between 100 and 999. Also all of the numbers need to be unique so they can't output more then one of the same number.
I am not sure why but it ignores my conditions. Ill type that I want 7 but it just outputs a bunch of random numbers. it dosen't stay in the ranges.

I am trying to build a c++ that reads user input and arrange letters in ascending order. for example, if the user input: Hello my name is Moe! the output will be: !aeeehillmmmnoos (ascending order)

ID | Location | Quantity
1 | 2 | 5
2 | 3 | 10

ID | Location | Quantity
1 | 2 | 5
3 | 4 | 8
2 | 3 | 10
I am trying to assign the integer value to unsigned char array. But it is not storing the integer values. It prints the ascii values. Here the code snippet
Code: uchar uc[100];
for(i=0;i<100;i++)
{
uc[i] = i;
}
The values which are stored in uc[] is ascii values.I need the integer values to be stored in uc[]. I tried to do it with sprintf. but the output is not as expected. if I print the uc[i] it should diplay the value as 0,1,2....99.
I am getting the hang of it pretty well. I created a program that asks the user to input arrays. Now, I need to calculate the average of the inputted arrays, and I need to place them in order from low to high. I have been struggling with doing these two parts for a while now and now decided that the book is not useful, I need some from some actual programmers. I attached my program.

We've only covered up to Functions and how to use reference variables inside the function parameter.
One of the hw problem that was assigned was to write a void function that takes three parameters( num1, num2, num3) by reference and sorts their values into ascending order, so that num1 has the lowest, num2 the middle value, and num3 the highest value. For example, if user enters: 14, -4, 8, then the output should look like this:
-4
8
14
I've completed the program with a bunch of if/ else if statements but I was wondering if there was a more efficient way to sort the numbers. Bear in mind, we've only covered materials up to functions so I can't use any other new techniques that we haven't cover yet. Here is my code:
// This program will take three int parameters by reference and sorts their value into ascending order
//so that num1 has the lowest value, num2 has the middle value, and num3 has the highest value
#include <iostream>
using namespace std;
// declare function with reference parameter that with sort numbers
void sortNum(int &, int &, int &);
int main ()

I have to put these numbers in ascending and descending order . The interesting point of the function is that sortMe does NOT re-arrange elements in the array; instead, it uses a second array, an array of indexes for the elements in the original array and then sortMe sorts the second array based on the values in the original array. A sorted version of the original array can then be produced with these sorted indexes. I'm not sure why the function is working, even though I called it in main.
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
void sortMe(int array[], int sortedIndexes[], int size, char mode);

changing a 9 digit integer into a new 9 digit integer through simple mathematical operations. For example, I need to change 123456789 into the new digit 456123789. Sometimes I need to change a 9 digit integer into an 8 digit integer. An example is 789062456 into 62789456. I can ONLY use simple mathematical operations (addition, subtraction, multiplication, division and modulo).
