| All,
| Well, now i modify a bit my code:
| Will it make sense?
It will only be legal if the memory pointed to by a has been obtained by a
call to new operator. Also if the pointer is NULL, then delete has no
effects.
It depends if a was allocated with new or not. If a was allocated with new,
it is legal. If it was not allocated with new, it is undefined and will
most likely cause a memory fault.
I'm creating a debug class called debug_mem_allocation for the purpose
of finding memory leaks.
I used macro's to replace the new and delete operators.
My problem is with trying to replace the...
I create a pointer to an item:
CardSession *cardSession;
Then, later, I use new to create an instance of the item and assign it

Hello,
This is a simple question for you all, I guess .
int main(){
double *g= new double;
*g = 9;
delete g;
cout<< sizeof(g)<<" "<<sizeof(double)<<" "<<sizeof(*g)<<" "<<*g<<" "<<endl;

Hello,
I'm confused by the pointer definition such as int *(p);
It seems if the parenthesis close p, it defines only 3 integers. The
star
is just useless. It can be showed by my program:

I am skipping a couple of steps in betweens, like inserting into a list
of ints and extracting from it. But this is the gist of what I am
trying to do
class A {
};
A *a = new A();
How does free() , delete() works?
If we allocate memory using the following statement
int *p = malloc(100*sizeof(int));
Inorder to release the memory we will call '"free(p) "
How does...
Is it safe to remove elements from an array that foreach is working on?

Hi,
I have a map containing pointers. When I destroy the map I want to
delete
all the pointers.
typedef std::map<std::string, const T*Table;
void destroy_map ()
{
Variable and constants
Use var or let for variables and const fror constants.
Var foo ='bar';
Let foo ='bar';const baz ='bar';
Functions
function $name$ ($parameters$) {
}

In our work, we often receive Excel tables with data in the same format. If we want to analyze these data, it can be difficult to analyze them because the data is spread across multiple Excel files...
