class A {
public:
void f();
protected:
A() {}
A(const A&){}
};
Examine the class declaration shown above. Why are the
default and copy constructors declared as protected?
1. To ensure that A cannot be created via new by a more
derived class
2. To ensure that A cannot be copied
3. To ensure that A cannot be used as a base class except
when public inheritance has been used
4. To ensure that A cannot be created/copied outside the
inheritance chain
5. To ensure that A cannot be instantiated as a static variable
I am DeePu sotware engineer working with EMC
corporation ,recently I had attended mcafee interview .
Their questions were at heights of stupidity , I don't know
what they want , I am a developer with 4 year
experienced .I am listing the questions asked
1:What is the flag in g++ to avoid structure padding
2:In wht order parameters are passed to stack
3:How you will edit code segment of an exe
You have to take 2 arrays of length 10. Input the values of
array 1 from the user. Then copy the values of array 1 to
array 2 in ascending order
For example if user enters 9, 5, 6, 8, 1, 0, 2, 7, 4, 3
then copy the smallest element i.e. 0 first followed by 1,
2 and so
Any one help me plzzzz.....
i have an assignment......
that is
______*********_______
Write a program that takes an equation as a string and does
the following:
Solve 8 parts to achieve 100% 1 - 5 are compulsory.
Input: 2x^2+3x+4=0
1) read a quadratic equation
2) print its coefficients (coefficients range is 0 to 9)
3) print the solution of the equation
4) tackle imaginary solution e.g. ( (2+3i), (2-3i) )
5) allow spaces within the input
6) after solving one equation; ask for an other, terminate
on empty line. *
7) tackle negative values as well *
8) tackle more than one values of same exponent (e.g. 2x^2
+ 3x^2 + 4x + 3 = 0)*
9) use strtok *
10) print the solution in fractions e.g. 1.5 should be
printed as (1)1/2 *
11) coefficient can be greater than 9**
12) values on both sides of the ‘=’ sign**
13) plot the graph of the polynomial**
14) use a compiler other than Borland**
15) submit before May 25, 2009 11:59 PM **

how can i access a direct (absolute, not the offset) memory
address?
here is what i tried:
wrote a program that ask's for an address from the user,
creates a FAR pointer to that adress and shows it. then the
user can increment/decrement the value in that address by
pressing p(inc+) and m(dec-).
NOW, i compiled that program and opened it twice (in 2
different windows) and gave twice the same address to it.
now look what happen - if i change the value in
one "window" of the program, it DOES NOT change in the
other! even if they point to the same address in the memory!
here is the code snippet:
//------------------------------------------------------
#include <stdio.h> //INCLUDE EVERY KNOWN HEADER FILE
#include <conio.h> //FOR ANY CASE...
#include <iostream.h>
#include <dos.h>
#include <process.h>
main()
{
int far *ptr; //FAR POINTER!!!
long address;
char key=0; //A KEY FROM THE KEYBOARD
int temp=0;
clrscr();
cout<<"Enter Address:";
cin>>hex>>address; //GETS THE ADDRESS
clrscr();
(long)ptr=address; temp=*ptr; //PUTS THE ADDRESS IN THE PTR
cout<<"["<<hex<<(unsigned long)ptr<<"]="<<*ptr<<" = "<<
(char)(*ptr);
//SHOWS: [address]=value=ASCII symbol.
while (key!=27) //WHILE YOU DONT PRESS ESC.
{
while(!kbhit()) //WHILE KEY IS NOT PRESSED
{
if (temp!=*ptr) { temp=*ptr; clrscr(); cout<<"["<<hex<<
(unsigned long)ptr<<"]="<<*ptr<<" = "<<(char)(*ptr); };
//IF THE VALUE HAS CHANGED, CLEAR THE SCREEN AND SHOW
//AGAIN
if (key=='p') {key=0; (*ptr)++; } //INCREMENT VALUE
if (key=='m') {key=0; (*ptr)--; } //DEC. VALUE
};
key=getch(); //IF A KEY IS PRESSED, READ IT FROM THE
//KEYBOARD
};
return 0; //IF ESC WAS THE KEY, EXIT THE PROGRAM
}
