Re: sprintf's char *format parameter

% is start of conversion specification
- is left justify the converted argument
10 is the minimum field width to be printed from the converted argument
. is a separator between minimum field width and precision
10 is the precision or maximum number of characters to be printed from the
converted argument
s indicates the type of argument to be converted is a null terminated
character string and also signals the end of the conversion specification

[C400-L] sprintf's char *format parameter






char password[NAME_SIZE];
char sy_password[NAME_SIZE]

sprintf(sy_password, "%-10.10s", password);


I'm not very familiar with C. Can somebody tell me what does %-10.10s
format means? Looking up some info on the web, it seems like the - sign
means left justify. s means convert to string pointer. I'm not
understanding 10.10.
