Array of pointer

Can I create an array of pointer with new operator?

Yes. Where are you having trouble?

I'm sorry. Because I've just learned C++, I'm still confuse about pointer in C++. Would you like to tell me how to create a pointer of array with new operator?

Type **ptr_array;
ptr_array = new Type *[256];

I'm not sure exactly what you want, so here goes...

A dynamically created array of int pointers:
int **myArray = new int*[10];

A dynamically created array of ints
int *myArray = new int[10];

Clarify what you want, try coding it yourself, and post your attempt here if you have trouble.

Can somebody tell me if this is correct, too ?

Code:

---

typedef int* pint;
pint *ppiRowIndices;

....

ppiRowIndices= new pint[iCount];

It seems to work but looks differnt then the code posted here. It wouldn't be too cool if it only worked because there are no overflow checks etc.

basically you did the same thing. the typedef gives a name to an int * is the only difference.

I did that because new didn't accept the "int*". :confused: Thats why I wondered if my code is correct. pint is just another name for "int*", so why would it accept that but not "int*"? Anyway, if it's correct and it works I'm happy. :)

thanks!

what compiler? can I see that line of code?

Also, once you have your array, remember that none of those pointers have been initialized.

Thank you. It's very helpful for me.

I understand the workings of an array of pointers, but I'm not sure about the application of it. Would this be a valid example?

Code:

---

void InitializePCharArray(char **array,int num)
{
for (int i=0;i<num;i++)
    *((&array)[num])=GetInput(); //return type char *
}

int main()
{
char **PPCharArray=new char*[10];

InitializePCharArray(PPCharArray,10);
return 0;
}

I'm really lost here!

:p Wow that was some serious overkill ey? I think I understand now, I drew a whole lot of diagrams out on paper, with arrows, boxes, and everything.
