Packing values into a single int
- by user303907
Hello,
Let's say I have a couple of variables like apple, orange, banana
I have 8 apples, 1 orange, 4 bananas.
Is it possible to somehow convert those values into a single integer and also revert back to their original values based on the computed integer value?
I found an example online.
int age, gender, height;
short packed_info;
. . .
// packing
packed_info = (((age << 1) | gender) << 7) | height;
. . .
// unpacking
height = packed_info & 0x7f;
gender = (packed_info >>> 7) & 1;
age = (packed_info >>> 8);
But it doesn't seem to work as it should when I entered random numbers.
