An odd pointer error

[tomy12]

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

int* p = new int(4);

This doesn't do what you think it does. This creates a pointer to one integer value and gives that the value 4. I think you mean you want to create a pointer to memory holding 4 integers?

int* p = new int[4];
