I compressed a char array by removing leading zeros from integer data and packed them tightly (without leaving spaces bit-wise). I wish to decompress it to get my original data back. The data is 8-bit and can have any number of zeros ranging from 0 to 8. I cannot exceed the 8 bit limit to store flags and cannot send another string of data as the communication speed is not reliable. I am working in C and removed the zeros by counting them and shifting.

Nice try, with just few corrections. You have to store a mark that will give you a clue how long was original value so you can decompress it back. Sure thing, there is nothing new under the moon so you can reuse such thing as VarInt:
