Your explanation was very usefull. I have one more doubt in the same context.

This assembly thing is quite new for me. In the cpp assembly line 7 states push 10.
So does that mean in Cpp the...

Can you tell me where the variable be put when it is declared as const. Will it go into const segment.

"You can also specify sections for initialized data (data_seg...

I have executed the below programm on both C and C++ compiler and got different results

#include <stdio.h>
int main()
{
const int a=10;
int *p=(int*)(&a);
*p = 20;
printf("address...

Good explanation.
Thanks Dave

So .... R you trying to say that its a standard ...
If at all its a standard, there should be some reason as of why the standard is not allowing it

That link doesn't provide the reason why the program crashes if the object is on stack.

Hi All,

Can we delete this pointer from a member function.

I have written three programs to try this. The first two crashes at run time while the third doesn't. Can somebody explain me...

Agreed to that ... Can you make it clear, when the initialization of virtual pointer with the address of virtual table will take place???

Why cant we have a virtual constructor?

All the materials give somewhat similar anwer to this question. "First the VPTR Pointer is initialised to it's proper VTABLE by the contructor which is...

Thanks, once again.

This explanation was very much usefull.Thank Wolf ..... Can you provide me the link to C++ standards.

Hi Guys,

I still didn't get answer for my question.

By reference to pointer I mean this
int * & x;
Here x is a refernce to a pointer

In the same way pointer to a reference is not...

Why pointer to a refernce is not allowed in C++?????

const int m=3;
const int n=4;
const int p=5;
int A[m][n];
int B[n][p];


Put your initializations inside main if you are using it locally or above main(global usage) if it is used in more...

Can you explain the problem?????

This is one way of going about it without much thinking

fn = [ Phi^ n - (-Phi)^-n ] / (2Phi-1)
for smaller values of n you need approximation.

Phi = ( 5^½ + 1 ) / 2 = 1.6180339 (the golden...

Have you checked your prog. The program is switching between am and pm.
I gave the input as 5 30 am and time difference 9. The o/p I got is 2:30pm. This is infact correct. Then why you are saying...

You should put equihrs=equihrs-12;

inside this if also
if(equihrs==12)

Other than that I dont see any problems

Some general advice

1) Donot use clrscr(), getch, gotoxy and all.....
2) Use prototype of main as int main(void) ( The one comment I usually get from the forum) or int main(int argc,...

l_var = l_var | (int)pow( 2, Array[i]);


What is the problem with this if I am making check for 30?????

Suppose in the array all 1, 2, 3 and 4 are present now after the operation
l_var = l_var | (int)pow( 2, Array[i] );

= pow( 2, 1) | pow( 2, 2)| pow( 2, 3) | pow( 2, 4)
= 2 | 4 | 8 | 16
= 10...

This seems to be a good sol. But should I check for 15 or 30 at the end

10
100
1000
10000
-----------
11110 -- 30 (dec)

Right??

Array can contain 1,2,3 and 4 any number of times. Its not necessary that array has all the four. But if all the four are present then the function should return true otherwise false.

What if only 1 is present 5 times ??? Then also the count will be greater than 4

I have to write a function which takes an integer array as input and it should return true if the array contains 1,2,3 or 4.

Conditions
1) The function should pass thru array only once.
2) Can...

"If a character is a string, change it to an underscore"
I guess Dave meant
"If a character is a space, change it to an underscore"

Thank you all for your suggestions.

hollystyles - Good material.

Using one directive the output is as I am expecting.
In this case it will give redefinition error. But when I use two not able to figure out what is happening

Here are some problem with your code

1)
printf("last name:");
scanf("%s",ln[i]);

replace it like
printf("last name:");
scanf("%s",ln);

Which compiler are you using???

I hevent gone thru your code ... You can do something like this

Random Number % Number chosen == 0
then
proceed
else
choose other random number.

Are you sure about this. I just want to confirm .... Do you know any good materials on this.

Modify your MarkNumber as shown below.

void MarkNumber(int input)
{
int loop=input ;
while (loop >= 10)
{
cout<<"0123456789";
...

int main(void)
{
int a = 20, b = 30;
printf("%d %d", a , b );
}


But why there is no change in the preprocessor output ( see above) ???

#include <stdio.h>


#define a b
#define b a
int main(void)
{
int a = 20, b = 30;
printf("%d %d", a, b);
}

Output will be 20 30, This seems to straightforward for me.

#include <stdio.h>
#define a b
#define b a
int main(void)
{
int a = 20, b = 30;
printf("%d %d", a, b);
}

Sorry Knorden ... Me too got it

Solution is simple.....

Instead of using for(i = 1; i < = numJobs; i++) use
for(i = 1; i < numJobs; i++)

The array was going out of bound.

I tried running the same code but didnt got any segmentation fault.
Just changed the prototype of main and try it
