Problem storing random number of bits to a byte.

Thank you for a brief explanation. So there are some problems with my concept or my limited knowlegde with arduino,

  1. As you said as an example...
    0 is represented by 00
    1 is represented by 10
    2 is represented by 11
    3 is represented by 110
    4 is represented by 011
    So arduino will store it as 1 byte so I have to read the high bits of a byte like for example for 1, B00000010, so I am storing this value in a byte variable "P" by shifting B00000010 << 6 , so the resultant is B10000000.
    Now I have to store the next value which is 3 for example which is B00000110 so now I have a problem that how can I know that the variable "P" have to store the value from index 2 so that the resultant will be B10110000, that is my problem...

The code below is that, I simply made a manual Huffman tree with specific frequencies. First I am serching for the highest frequency , then get its index number and if the sensor value is equal to that index it will store a specific compressed value. So after that I have to store it in a byte because arduino minimum data type you can play with is byte so I have to store it in byte efficiently, that is my problem I am facing.

byte Huff(byte K){
int freq[]={5,2,3,4,4,3,2,1};
int first = freq[0];
byte firt=0;
byte K=0;
byte secd=0;
byte thrd=0;
byte frth=0;
byte fift=0;
byte sixt=0;
byte sevt=0;
byte Code=B00000000;
byte chk=0;
