Write a program that computes how many feet an object falls in 1 second, 2 seconds, etc., up to 12 seconds.
1.Have a procedure called FallingDistance which has one input parameter, seconds, and one output parameter, distance.
2. Compute the distance in feet an object falls using this formula: d = ½ gt2
(where g = 32.2)
3. The main program should call FallingDistance within a loop which passes the values 1 through 12 as arguments.
4. Print a table with seconds and falling distance in feet.
In C++, the procedure is called a function. Instead of using an output parameter, your C++ function FallingDistance should return a result of type double. This is what I created:
#include <iostream>
#include <cmath>
#include <string>
using namespace std;
const double g =32.2;
double fallingDistance(double);
I'm just having a bit of troubles on getting my code to work from this psuedo code - It has been asked for the object to be set at at least a height of 30 units (in the y property). -
#include <iostream> #include <Windows.h> #include <conio.h> using namespace std; struct Player { float position ; float velocity ;
I was getting errors and I looked into the error and it told me to fix it by adding Code: { } in my case statements. I did, it compiled but fell through the whole thing. Lets say I enter 1, it outputs the was not found 5 times in a row.
Code: void addressbook::EditNameOrDate() { std::cout << "Enter 1 to Edit the contacts First Name: " << " "; std::cout << "Enter 2 to Edit the contacts Last Name: " << " "; std::cout << "Enter 3 to Edit the contacts Street Address: " << "
Im developing a game where i need 18 animated images to fall into view from the top of the screen with 14 of type A visible and 4 of type B. I then need to be able to drag these items off screen or into a basket at the bottom of the screen.
My current issues are:
I cant seem to drag the images off screen or to the basket when they are animated.I cant make the images fall randomly with delay between them.I was able to make the 18 appear, but not as listed above in the description with 14 of type A and 4 of type B.
This actually should work, because it is passing address of polymorphisms object.I have tried changing prototype of test in Data.h, but failed.passing object address/pointers in C++.
This is my question : Define a class named HOUSING in C++ with the following descriptions:
Private members REG_NO integer(Ranges 10 - 1000) NAME Array of characters(String) TYPE Character COST Float
Public Members -Function Read_Data( ) to read an object of HOUSING type -Function Display() to display the details of an object -Function Draw Nos( ) to choose and display the details of 2 houses selected randomly from an array of 10 objects of type HOUSING Use random function to generate the registration nos. to match with REGNO from the array.
Now I' trying to do this by this way
Code: #include <iostream.h> #include <conio.h> #include <stdlib.h> class housing { private: int REG_NO; char NAME[10];
[Code] .....
I am trying to pass the entire array of object in DrawNos(). but getting compilation error -
32: 'housing:rawNos(housing * *)' is not a member of 'housing' 48: Structure required on left side of . or .*
What is the problem? How can I pass the array of object in function and use it.
I just spent 3 hours writing and debugging 37 lines of code. Is this normal or am I "below average" in coding abilities. I come from a C background and decided to write C++ code that I finally got right as shown below for the specific example:
I think it was more the learning along the way that consumed atleast 75% of my time for this specific case. But then again, I read that programming always entails learning along the way and so its somehow no excuse for the long time taken in this specific case.
So as a matter of interest, what pace do all of you operate on, on average? i.e. LOC/day, Debugs per day or any other indicator of productivity?
Is there a way to put a mp3 file into a c program without having the windows media player pop up in the background each time you compile the program? I just wanted to input a few seconds of an audio file..
when i compile my code i get this error : "error : variable-sized object 'largeArray2' may not be initialized"
Code:
float give_coefficients_routh_table_and_fill_two_first_lines(int denominator_degree) { float largeArray2[20][20] = {0}; int l = 0; int c = 0; int e = denominator_degree ; for ( e = denominator_degree; e>=0; e--)
I'm trying to convert dicom .dcm file to .jpeg using Imebra in C++ app using QT Creator as dev environment.
I've downloaded Imebra and was able to run QT project example for Dicom2Jpeg conversion successfully. But when I tried to copy same code to my C++ app it failed to run with following error msg:
malloc: * error for object xxxxxx: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug
I have followed steps on adding Imebra files to my project as it was shown on Imebra site. Also used their qt project as example. My main.cpp open dicom file, then loads it to dataset, then calls my dialog window. It crashes on loading dataset.
#include "QApplication.h" #include "QHBoxLayout.h" #include "mydialog.h" #include "iostream.h" include "library/imebra/include/imebra.h" int main( int argc, char ** argv ){
[Code] ....
Deeper debugging showed that source of error is in JpegCodec.cpp file readStream() function when checking JpegSignature to see if it's in wrong format with resulting internal PUNTOEXE error "detected a wrong format".
Interesting thing is that while running same test dcm file using given dicom2jpeg example (which has exact same code of opening file and loading it) gives no errors and converts to jpeg successfully. So I know it's not the file issue, but the way imebra code is integrated into my C++ app.
My dev environment: macbook pro with Lion OS, QT Creator, QT project, C++ code, ITK library added, Imebra files are completely integrated as part of the Qt project.
So, my question is how do I work/link/reference/call Imebra functionality in QT project? Am I forgetting to link something, or some object is not instantiated/deleted on time?
I'm interested in learning how to write the software for audio synthesizers. a friend of mine started on the hardware side for them and, as i have no experience with this type of code.
I am writing a program where all work is done in the class methods. Main is used to call the methods. I need to know how to get a loop to work without any variables in main that can be used outside the methods. This is what I have in main:
#include <iostream> #include <string> using namespace std; #include "FerryBoat.h" int main() { //create a constructor for a ferry boat FerryBoat myBoat('B', 20, 'A');
I am trying to create an on-line product store. I'm having trouble with setting up the code to correctly acknowledge quantity desired per product item in the shopping cart at check-out. I want to be able to capture multiple impressions/hits/clicks per item and increase the # in the quantity box each time someone clicks on the same item. For example, if product A is clicked 3 times, then the quantity in the shopping cart should show "3". If it's clicked 5 times, it should show "5" and so on ... However, right now, it's showing the product multiple times in the shopping cart with a quantity of "1" for each time the item was clicked. How can I correct this?
will copy constructor does object initialization using another already created object? I understand that it can be applied for object initialization and not for assignment.Is it correct?
I have a method to take a Tile object and make an instances of it based on some data from the original object. Than it is suppose to manipulate the a specific instance and save the results. The first loop through it works but it changes all instance as well as the base.
public static int recurse(int count, Tile[,] b,Huristic h,int check) { if (check==1) { boardState.Add(B)/>; return check; } if (check == 0)
