Parameterised constructor is invoked, in that j=x ; i.e., j=10 will assign (here j is global)
j= 10 will be printed by calling display().
int &s = i; // i=10
int &z = j; // j=10 (here j is global, value of j is 10
i++; // 11
cout<< s-- << " " << ++z; // 11 11
j= 10 will be printed by calling display().
int &s = i; // i=10
int &z = j; // j=10 (here j is global, value of j is 10
i++; // 11
cout<< s-- << " " << ++z; // 11 11

Values of x and y are overwritten.
It becomes x=10, y=20.
It becomes x=10, y=20.
