to count number of bits

hi
i want to count total no of bits in this example
zb=
00000100 1 0 01000100 0 00111110 0 01000100 0 00000100 0 00000010
this includes a delimiter space too so i don`t knw how do i write a code for this

sum(zb=='1')

Assuming it is in character format ("includes a delimiter space" don't
see that it could be anything else, just saying)...

  Since zeros are bits too, I would think the total number of bits should be:

 sum(zb=='1'|zb=='0')

Another one:

sum(~isspace(zb))

Best.

Hmmmmm....I interpreted it as total number of set bits but you're right
he doesn't say that exactly.

Guess OP can choose which it is wants.
