Segmentation Fault using double pointers

Question

I'm getting segmentation fault while handling with double pointer in the below code. I've spent way too much time and couldn't find what the error was.

#include<iostream>
using namespace std;
int main(){
    int *p,**pp,n=2;
    p=new int;
    pp=&p;

    for(int i=0;i<n;i++)
    {
        cin>>*(*(pp+i))>>*(*(pp+i)+1);
    }
    for(int i=0;i<n;i++)
    {
        cout<<*(*(pp+i))<<" "<<*(*(pp+i)+1)<<endl;
    }
    return 0;
}

Not sure if this is a noob question.

Answer 1

Maybe this is what you need:

int *p, **pp, n = 2;
p = new int[n * 2];
pp = &p;

for(int i = 0;i < n;i++)
    cin >> *(*pp + n*i + i) >> *(*pp + n*i + i + 1);
for(int i = 0;i < n;i++)
    cout << *(*pp + n*i + i) << " " << *(*pp + n*i + i + 1) << endl;

delete []p;
return 0;
