a strange pointer error

[Kubani]

Hi,

Would you please have a look at this simple code (its name is test1)? I don't know why my VS 2015 compiler gives an error :(

#include <iostream>
using namespace std;

int main() {
	int* p = new int(4);
	*(p + 0) = 2;
	*(p + 1) = 4;
	*(p + 2) = 6;
	*(p + 3) = 8;
        
	return 0;
}

The error: test1.exe has triggered a breakpoint.

I have installed my VS 2015 on Windows 7

Interesting it run's on my VS2013 CE.

However the problem is that you access memory that doesn't belong to you.
int* p = new int(4);
You just created a pointer to an int with the value 4. I guess you wanted to create an array int* p = new int[4];

Yes, you are right. Thank you very much. :)

I only have forgotten the correct form. I don't know why the programming statements are that volatile!

PS: Something more interesting, cpp.sh runs it successfully!

cpp.sh runs it successfully!

This code has no successful behaviour, because there is no correct behaviour.

You're into behaviour explicitly labelled as "undefined"; the compiler writer can do whatever they like.
