This might be elementary.I have a structure with an int and char . The size of the structure returned is 8. Shouldn't it be 5?

struct temp2
            int i;
            char j;
      temp2 objtemp;
      cout<<sizeof(objtemp.i);   //returns 4
      cout<<sizeof(objtemp.j);   //returns 1

      cout<<sizeof(temp2);  //returns 8

no, it should be 8.

Its the alignment, what matters.

if you want to change it, you can use

#pragma pack(2)

now size will be 6

#pragma pack(1)

size will be 5
