Problem with the placement of new operator

[Knightrider29]

Here I submit two codes.The former one works while the other doesn't..Why?
#include <iostream>
using namespace std;

int main()
{
int * talk = new int;
*talk = 29;
cout << "The address of talk is " << talk << " and it's value is " << *talk ;
return 0;
}


#include <iostream>
using namespace std;

int * talk = new int;
*talk = 29;

int main()
{
cout << "The address of talk is " << talk << " and it's value is " << *talk ;
return 0;
}

This is an executable statement:

*talk = 29;

It must be within the body of a function or an initialization expression. It can't be just anywhere in your program code.

[Knightrider29]

What exactly does an executable statement mean?
And why shouldn't it be outside the function's body?

Ps: Thanks for the reply! (:

This is a declaration/definition:

int x = 7;

Declarations/definitions can generally appear anywhere.

This is an executable statement:

x = 7;

They can only occur within expressions or as statements in a function body. Why? Because the C++ standard says so. End of story.

Is there any way to assign 'talk' as 29 directly in the line
int * talk = new int; ?

Assign, no. Initialize, yes.

int* talk = new int(29);
