Why Pointers and not double?

Hi, I wanted to ask why is it not possible to store binary values of 8 bytes in a double bucket?

And also after watching the video, i am still confused why the sizes of the pointers are same?

hi @shiwanitehlan_5cf99744487d0b23
the range of values an int can represent and that a double can represent are implementation defined - but a double certainly cannot support every integral value in the range it can represent
sizes are same becoz pointers are addresses so addresses have same size either its double int anything
