Visual C++ :: Creating A Function That Needs To Determine Perfect Scores
Jun 24, 2013
This program is incomplete as I am having difficulty creating the function that needs to find the number of perfect scores entered by the user. I have everything but the function complete ,here is my code:
Code:
// Write a modular program that accepts at least 10 integer test scores from the user and stores them in an array.
// The main should display how many perfect scores were entered (i.e., scores of 100), using a value-returning countPerfect function.
// Input validation: Do not accept scores less than 0 or greater than 100.
#include <iostream>
using namespace std;
int countPerfect(int intArray[], int); // Function prototype

I want to detect the type in a function template, like this:
template <class myType> myType Function (myType a, myType b) {
//Detect the myType
If (myType is int)
[Code] ......
Is that possible?

I'm am having a few issues with this program, they stem from passing the color.h and .cpp into another .h and .cpp, and frankly getting how those two things really fit together.
For this problem, you will design and implement 2 classes and then write a driver function to test these classes. The first will be a C++ class for an abstract data type color with a public enumeration type colorType that has the color values shown in Listing 10.8. Your abstract data type should have an attribute for storing a single value of type colortype and member functions for reading (readColor) and writing (writeColor) a color value as well as setting and accessing it. The function readColor should read a color as a string and store the corresponding color value in the value attribute of a type color object. The function writeColor should display as a string the value stored in the value attribute of a type color object (see Figure 7.5). Modify class circle and the driver function in Listing 10.9 to include and use this class. You'll need to remove the declaration for color in class circle. Test your modified driver function with the new color and circle classes.
The second class will be to design and implement a rectangle class similar to class circle. Be sure to incorporate the new color class you have written and tested in the first part of the programming exercise. Write a client program that asks the user to enter a shape name (circle or rectangle) and then asks the user for the necessary data for an object of that class. The program should create the object and display all its attributes.
The circle class .h and .cpp files as well as the original driver function will be supplied. You are to provide the .h and .cpp files for the new color class and the modified driver function as well as the .h and .cpp files for the rectangle class and the client program that uses all three classes.
color.h
Code:
//color.h
//Color class definition
#include "stdafx.h"
#ifndef COLOR_H

Okay so suppose that a text file grade.txt contains an unspecified number of scores. How would I program that reads the scores from the file and displays all the scores, their total and average? Scores are stored in the format of one score per line. Im having trouble with the whole #include <fstream> file and how to lay it all out in visual studio.

i have a project where i create a dice game, the user rolls 2 dice and the computer roles 2 dice. the player that wins 3 out of 5 rolls wins the game. I have completed the requirements, but i wanted to create a pass by value function for "void Dice()", I'm not too sure how that works?
Code:
#include <iostream>
#include <ctime>

My assignment is to create a C++ Program to find the sine of a number without any library other than iostream by using Taylor Series:
sin (x) = (x/1!) - (x^3/3!) + (x^5/5!) - (x^7/7!) + (x^9/9!) ...... (x^n/n!).
Here is what i have done till now:
#include <iostream>
double fact (int f); //declaration of factorial function
double power(double x, int y); //declaration of power function
double sin(int x); //declaration of sine function
//double cos(int x); //declaration of cosine function
//double tan(int x); //declaration of tangent function

I am currently in a beginner C programming class. I have written most of my code and the problem that I am running into when i compile and run the code. I am able to input more than required scores for input. I think my code is wrong from line 126-136. The program runs fine with no errors. I'm just unable to input the required number of scores allowed.

I use new to allocate a buffer, as follows:
BYTE *p;
p = new BYTE[20];
...
delete p;
After p is deleted, if I do NOT assign NULL to p, is there a way to determine whether it has already been freed?

so in declaring a display function prototype only that displays a student test scores in the format (student name tab number of scores tab test scores )
is this right?
#ifndef STUDENTTESTSCORES_H
#define STUDENTTESTSCORES_H
#include <string>
using namespace std;
class StudentTestScores{
private:
[Code]...
and also how do we call the display function if it is in a class from the header file onto the main cpp file.

I would like to make a handler for input events, but not be required to define all the functions.For example, if I had
void mouseDown(int button,vec2 pos);
void mouseUp(int button,vec2 pos);
static void mouseStateHandle(int button,int state,int x,int y) {
switch(state){
case DOWN:
[code]....
in the 'mouseStateHandle' function? I don't know enough about C++ to be able to come up with a solution.

I'm trying to determine (from my Win32 process) if a Metro (or a Modern UI) app is currently displayed on the screen. I found the IAppVisibility::GetAppVisibilityOnMonitor method that can do just that, and I even found a C++ sample, but my issue is that I'm compiling it with the Visual Studio 2008 that does not have the definitions for the IAppVisibility interface, so the following:
Code:
#include <Shobjidl.h> //Earlier version
IAppVisibility* pAppVis = NULL;
HRESULT hr = CoCreateInstance(CLSID_AppVisibility, NULL, CLSCTX_INPROC_SERVER,
IID_IAppVisibility, (void**) &pAppVis);
Results in a set of errors:
Code:
error C2065: 'IAppVisibility' : undeclared identifier
error C2065: 'IID_IAppVisibility' : undeclared identifier
how to define them?

Find the perfect numbers between a starting value and a finishing value entered by the users. Display the results to the screen.
I've been told that I need to modify things under the void and the calcdiv in my main () but I can't seem to figure it out. It needs display the perfect numbers between the starting and finishing value. e.g. 28 and 429.
#include <cstdio>
#include <iostream>
#include <cstdlib>
#include <cmath>
using namespace std;

I am overriding OnSaveDocument in my MFC document class to strip out the carriage returns when saving my app's document to a UNIX file system but not when the user is saving a file to a Windows file system.
Is there a way to determine if the lpszPathName in OnSaveDocument(LPCTSTR lpszPathName) is a UNIX or Windows file system?
Note, I want to avoid hard coding server names and I want to avoid overriding the FileSave dialog and forcing the user to select Windows or UNIX.

/* Task: create a function that determines prime number and use it to print out prime numbers from 0-50: */
Function prototype: Should return a `bool` (because it answers a yes/no question) and should take in a single int (to ask whether it's prime).
- An int greater than 2 is prime if it is not divisible by any number between 2 and itself, not including itself.
- Use this function to print out the primes less than 50. Check it against my list:
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47
#include <iostream>
using namespace std;
int prime(int&x) {
if(x%2==1)
[Code] ....
It is printing out the correct prime numbers but also printing this between each number: 1629974960

I'm trying to create a function that determines the largest value in the array and then outputs the value and index. I want to values in the array to be random so I tried using the rand function, although I'm not sure where I'm supposed to put it. My main problem (I think) is outputting the correct values...
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
void lastLargestIndex (int numbers[], int arraySize);
int main(int argc, char** argv) {
int number, arraySize = 50;

Write a program asks the user for a positive integer value and then prints out all perfect numbers from 1 to that positive integer. I have been trying for some time, i found a way to check if its a perfect number or not but could not find a way to prints out all perfect numbers from 1 to that positive integer. I am here so far.
#include<iostream>
#include<iomanip>

#include<fstream>//data file / result file
#include<iomanip>

I have to write a code which would determine either a URL address is correct or not.
Now, a valid address should look like: "www.something.something.uk".
It has to have 3 dots, 3 w-s in the beginning, and it must end with "uk".
E.g.
Valid addresses:
1. www.jce.ac.uk
2. www.tr2213.oi34.uk
Invalid addresses:
1. www2.jce.ac.uk
2. òæøéàìé - îëììä à÷ãîéú ìäðãñä éøåùìéí - ìéîåãé äðãñä ìúåàø øàùåï
3. www.something.uk
Just to be clear, this criteria mentioned above is not real, just homework
Code:
#include <iostream>
#include <string.h>
using namespace std;
int isValid (char s[])
{
int dots=0;
[Code] ......
It tells me both strings are incorrect but the first 1 is.

I wanna create a DLL from my C++ program. My output of my C++ program is a text file called Centre_Cartouche.txt My output is two text files called brd.txt and sym.txt
At the beginning my program was just a main which contains all development (Main.cpp). Now I created function (in _Cartouche.h and _Cartouche.cpp).
My debugger tell me that the simulation works. But my file Centre_Cartouche.txt is not create.

How to create/use a graphical interface. Especially since Microsoft has removed Windows Form Application support from Visual Studio 2012 and 2013.
I know that Windows Form Application is still supported with C#, but C# is definitely not an option as the program I am developing is heavily depended on some of C++'s more advanced features not present in C#.
Is there an alternative to Windows Form Application? I would definitely prefer one, as I doubt that some workarounds would work for long. What are common ways to create a GUI application in C++? There certainly must be some ways. In Java one would use something like JFrame.
Crossplattformcompatibility: The program I am creating is a Microsoft Windows program only. So I don't care if it runs on Linux or Mac. It only has to run from Windows 7 onward. So if there are more than one standard ways to create a GUI, I would prefer the one working best for Windows.
By the way, I am using Visual Studio 2013.

I'm turning mad with a little problem with Visual Studio 2008 and MFC. I'm working on a project actually and I'm trying to create an SDI Application. Right, now I want to add a dockable DialogBar. Well, the first time I added it with the resource view, I can create the bar without problems. But... I want to add some controls like a couple of ListBox, buttons and so on. The program doesn't allows me to create member variables for these controls. The option appears in grey.
Searching a little, I found that it's mandatory to create a new class derived from CDialogBar and "enhance" it with the Message handler and so on. I've been reading some tutorials and it didn't work for me.
