Compiler Showing Errors When Getting Address of a Variable?

Code:

#include <iostream>
#include <string>

using namespace std;

int main()
{

    int x;
    int p_x = & x;
    *p_x = 2;


    cin.ignore();
    cin.get();

    return 0;
}

Compiler errors:

Code:

Error	2	error C2100: illegal indirection	c:\users\swadesh\c++ programs\pointerz\pointerz\pointerz.cpp	11Error	1	error C2440: 'initializing' : cannot convert from 'int *' to 'int'	c:\users\swadesh\c++ programs\pointerz\pointerz\pointerz.cpp	10
	3	IntelliSense: a value of type "int *" cannot be used to initialize an entity of type "int"	c:\users\swadesh\c++ programs\pointerz\pointerz\pointerz.cpp	10
	4	IntelliSense: operand of '*' must be a pointer	c:\users\swadesh\c++ programs\pointerz\pointerz\pointerz.cpp	11

You forgot to declare p_x to be a pointer.

Thanks, That solved it.
However, "Alex Allain" in his C++ book wrote the following code without the declaration you mentioned.

I guess he made mistake.

If i were you i would notify him with an email about it

probably a typo
