Difference between int &double

Answer 1

int uses up 4 bytes of memory (and it CANNOT contain a decimal), double uses 8 bytes of memory.

If you want to use a decimal, use double, which is a type float variable. Also, if you are planning on using huge numbers go with double.

If you know you won't have a decimal and the numbers will be small, use int.
