Why there is output difference for give code in c++ 11 and c++ 17?

I have a piece of code

     #include <bits/stdc++.h>
      using namespace std;
      typedef long long ll ; 
      int main() 
      { 
             ios_base::sync_with_stdio(0);cin.tie(0);cout.tie(0) ; 
             int i, j;
             i = j = 5;
             j = i++ + (i*10);
             cout<<i<<" "<< j <<" "<<i++;

    }

Output of code for c++ 17 is : 6 65 6 Output of code for c++ 11 is : 7 65 6

Why such a difference ?
