bad pointer declaration?

Here's what I have in my main function:

int *first = 29, *second = 50;

Attempting to compile, there is error C2440: cannot convert from 'const int' to 'int *'

What am I doing wrong?

I dont think you can declare like that, you need to do like this

int *first, *second;

oh also, yer assigning a literal to a pointer, where it may not have an address, what you need to do is something like this

int *first = new int;
*first = 23;

that way a memory allocation has been made, then you just assign that value into the already allocated memory.

I tried using
Code:
  int *first, *second; [code]

That was my first attempt, it also gave an error, but I think it appeared during my build attempt.

Well, i'll try that other part you had. [sig][/sig]
 
Okay, I tried
Code:
 int *first = new int;
It compiles okay, but when I attempt to build the executable, I get &quot;error LNK2001: unresolved external symbol _wWinMain@16&quot;
When I check the explanation of the error, i'm told this happens if I don't have an entry point to wWinMainCRTStartup, and I need to type this value into the Linker Settings dialog box; I found what seems to be this box, and this value is already there.
Perhaps my problem is something else? I accidentally linked a different file to my project; in my project settings I have clicked the box to exclude it from the build....how do I completely get rid of it? [sig][/sig]
 
I don't know what is this question about. If you want to point the address 29 you need declare like this
int* first=(int*)int; [sig][/sig]
