Reads in the size of a square from the screen;
2. Prints a hollow square of that size out of “-“, “|” and
blanks on screen;
3. Prints the same hollow square onto a text file.
Your program should work for squares of all side sizes
between 1 and 20.

I want to write a C++ language program that:
1. Reads in the size of a square from the screen;
2. Prints a hollow square of that size out of “-“, “|” and
blanks on screen;
3. Prints the same hollow square onto a text file.
The program should work for squares of all side sizes
between 1 and 20.
#define CUBE(x) (x*x*x)
main()
{ int a,b=3;
a=cube(b++);
printf("%d %d",a,b);
}
What should be the value of a and b? My calc a=4 but syst
a=6 how pls tell me if you know it?
given the code segment below
void main()
{
cout<<"my no. is";
}
question is how can we get the output hai aravind my no. is
99999999999 without editig the main().
write a code for this. serial_number contained in the
header of the file will be read , if this serial number is
less than a previous serial number within a successfully
processed file, or is the same as another serial number
within a successfully processed file, or if the field
contains anything other than 7 digits, then the file must
error with the reason ‘Invalid SERIAL_NUMBER’.
class CTest
{
public:
void someMethod()
{
int nCount = 0;
cout << "This is some method --> " << nCount;
}
};
int main()
{
CTest *pctest;
pctest->someMethod();
return 0;
}
It will executes the someMethod() and displays the value
too. how is it possible with our creating memory for the
class . i think iam not creating object for the class.
Thanks in Advance...

Question In a class, there is a reference or pointer of an
object of
another class embedded, and the memory is either allocated
or assigned to the new object created for this class. In
the constructor, parameters are passed to initialize the
data members and the embedded object reference to get
inialized. What measures or design change should be advised
for proper destruction and avioding memory leaks, getting
pointers dangling for the embedded object memory
allocation? Please suggest.

There is something to be taken care in destructor, in copy
constructor, suppose the memory is assigned to the embedded
member object pointer with the parameter passed value, but
if some other objects of different class also are pointing
to this memory, then if some one deletes the object then
this class member pointer object will become dangling, or
if the object is not deleted properly then there will be
memory leak. Please suggest the design change required to
handle or avoid this situation

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
}
//---------------------------------------------------------
