Thread: finding MSB in a string

hi,

i'd like to find the most significant byte or bit within a string of chars. the size of the string is not set and can vary.

my char is something like:

Code:

unsigned char mystring = "WWW003674574574asdgasdgas000000";

and i'd like to find the HIGHEST occurance of a non zero character (in this case s i think) and display it as the address it is contained in. the data is written into the string after bieng received from a port starting at "WWW"

i'll then search through another character and display the diference between the two strings as a number of bytes.

is there a specific function that will do it or do i need to use

Code:

if

loops to find occurances of non zero characters?

thanks
