C++ :: How To Make A Class Final
Oct 5, 2013Just mark the destructor final: [URL] ....
Well, sort of - my question is, since the destructor has to be virtual in order to be marked final (you get an error otherwise), does this cause virtual function overhead anywhere, or add a vtable?
C/C++ :: Array To Only Print Out Final Average And Final Maximum Score With Final Minimum Score
Aug 27, 2014#include <stdio.h>
float total, avg, max, min;
float judge[4];
int index;
int array[4];
int main() {
total = 0.0;
max = array[0];
min = array[0];
[Code] ....
I dont understand how to make the array when it prints out only print out the final average and the final maximum score with the final minimum score but what its doing at the moment is just giving an average for each individual score taken...
Minimum and maximum scores are displaying 0.0
And it displays these things 4 times in a row i just want it to be displayed once.
C/C++ :: Final Output Needs To Print Initial And Final Values
Jan 28, 2015I have a program that is reading six characters from a text file, swapping every other character(ABCD would read BADC), and then adjusting their value based on a user's adjusted value input. If the adjusted value is 5 then letter A becomes F.
The final output line should print the initial six characters followed by the final six characters after the swap and encrypt adjustment.
I can only manage to print the final characters. Am I far off thinking I need to use pointers to point to the original character values?
One more thing: instructor wants us to complete this project as simply as possible meaning without the use of arrays, loops, switch statements, etc.

C :: CLASS Keyword In Function Names
Sep 24, 2014I'm trying to read a C code, but there are functions including CLASS word at the titles of functions. Is it a correct implementation?
For example: double CLASS getreal (int type)

C++ :: Program That Compute Final Average Grades Of Class
Jan 28, 2013An instructor needs you to write a program that will compute the final average grades in her class. There are 5 students in the class. Each student must take 2 exams and 4 quizzes as part of their final grade. The weight of each toward the final grade is as follows:
Exam 1 – 30%
Exam 2 – 30% Quiz 1 – 10%
Quiz 2 – 10%
Quiz 3 – 10%
Quiz 4 – 10%
You must use arrays to store each students 3 digit ID number, exam scores and quiz scores. A multi-dimensional array is mandatory. Request from the user the information needed then output all of the information as well as the final average grade for each student.
C++ :: Make Class Created Static Inside Another Class?
Dec 17, 2013it seems everytime i use statics in a class i come across with a porblem.
this time i wanted to make a class i created static inside another class.
MainVariables.h file
static fge::window mWinMain;
if someone ever wants to reach it
MainVariables.cpp file
fge::window MainVariables::mWinMain;
...
...
fge::window MainVariables::GetWinMain()
{
return mWinMain;
}
but when i created some other MainVariables classes at other places instead of them reaching to the same window two window is being created.
yes i know maybe there are better methods but currently i m working on polymorphism and i need some static members.

Jun 30, 2014for starters i hope this question wasn't posted yet.i want to write a small program that askes the user what he wants to do , and then executes the comand in system . But for some reason it doesn't quit on the key word this is the code:
Code:
#include <stdio.h>
/*a simple interaction programme that schow the system options*/
#define systemt "x1b[32m" /*changes the color to green for system output*/
#define user "x1b[0m" /*changes the color to white for user input*/

Is there something wrong white the code or does the system bock me from reusing the choise string. i'll inculde the original c file as well
C++ :: Use Of Virtual Keyword In Destructors
Jan 6, 2014have a look at the following code :
class Base
{
public:
virtual ~Base()
{
cout << "Calling ~Base()" << endl;
[Code]...
Now this program produces the following result:
Calling ~Derived()
Calling ~Base()
i was reading online and got stuck here. i am unable to understand why 'calling ~Base()' is been printed here? when we reached delete pbase; in int main() it goes to Base class first and finds that its destructor is virtual so it goes to Derive class and finds another destructor and executes it but why does it prints ~Base() in any case?
C++ :: Virtual Keyword In Inheritance?
Feb 19, 2014How to put virtual keyword in the function of the base class. Will the function still be over-written properly? What will happen if I
(1) call function from base class pointer
(2) call function from derived class pointer
(3) call function from derived class object
If the virtual keyword is present, the over-written version will be called in all cases, am I mistaken?

C++ :: Alternate Keyword For Getch Function
Aug 18, 2014I was trying to make a tic tac toe game where the user can play against the computer
It s in borland c++ and not in c++ 11 so i wanted to convert it into c++11. My program shows error since there is nothing called conio.h in c++11. Hence I want to know if there is any alternate keyword gor the function getch() so that i could ask the user to press [ENTER].

C/C++ :: Make Class That Can Only Have One Object Of It Created?
Oct 7, 2014make a class that you can make only one Object of it.
For example if you have Class A.
Let's say you create one object A* a=new A();
Now the next time you, try to create another object. For example:
A* b=new A(); What will happen is that b will get the same object (or reference) as a. In other words hey'll be pointing towards the same place. So basically you'll only have one object of it created. I tried doing it but I couldn't quite make it.
Here is what I tried: (but couldn't complete the exercise)

public string AuthenticateWithDB(CUiPontisDatabaseSpecification pdb, string sUserId, string sPassword,
bool bCreatePersistentCookie)
#2
public static void ChangeConnection(Util.ODBC.ODBCDSN odbcInfo, CPonDatabaseVendorType dbType, string uid, string password)

C/C++ :: How To Save Triangles / Polylines Into Vector Using New Keyword
Oct 11, 2014In C++ by FLTK, to define a circle we use some code like this:
Circle c(Point(x,y), r);
And we can using vector_ref put and save them in a vector, like:
Vector_ref<Circle> vc;
vc.push_back(new Circle(Point(x,y),r));
Ok, those were about Circle and no problem till now!
Triangle can be defined like this for using in codes:
Graph_lib::polyline poly;
poly.add(Point(x1,y1),r1);
poly.add(Point(x2,y2),r2);
poly.add(Point(x3,y3),r3);
and this is a vector to saving them:
Vector_ref<Graph_lib::Polygon> vp;
The problem is that how to save/put triangles/polylines into that vp vector using new keyword like the circle does?

C++ :: How To Make Private Member Accessible Outside Class
Aug 9, 2013The question says that:
#include<fstream.h>
#include<conio.h>
#include<stdio.h>
#include<string.h>
[Code].....
But then the 2nd part of the question itself says that "Acno entered by the user". So we need to identify/search for an account with that Account Number. How can we do this without comparing Acno with S.Acno? I know that S.Acno is not accesible as it is a private member but then how to compare Acno without even using a member function(public) that can return the value of Acno?
