is it possible to create array of pointers and set + get its elements using a class like this?. make changes/add to the class as needed. show actual code, if possible.
class t
{
t::t()
{
}
t::~t()
{
free(array);
array = NULL;
}
void set_size(int s)
{
array = new int [s];
}
void set(int n, int x)
{
array[n] = x;
}
int get(int n)
{
return array[n];
}
int *array;
};
If you want array to store pointers, you'll have to make it an array of pointers:
array = new int* [s];
array will be pointer to an int pointer, like this:
int** array;
When you set the size in your code, if the size has already been set, you will be losing all the already stored information and you'll have a memory leak, so you'd best do something about that.
When you want to set an int* in the array, pass in the int*
void set(int n, int* x)
{
array[n] = x;
}
Similarly, when fetching an int*, make the return type int*
int* get(int n)

class t { t::t() { } t::~t() { free(array); array = NULL; } void set_size(int s) { array = new int [s]; } void set(int n, int x) { array[n] = x; } int get(int n) { return array[n]; } int *array; };
