parsing - How to parse simple string in C? -


i have string following format:

start 123

i parsing way:

if (strstr(line, "start") == line) {     int number = -1;      if (sscanf(line + strlen("start "), "%d", &number) == 1) {         printf("start %d\n", number);     } }

is there better way in c?

yes can use this:

if (sscanf(line, "start %d", &number ) == 1) {

no need 

if (strstr(line, "start") == line) {

any more

if want check more: check there no characters after number , can use following format:

char c; if (sscanf(line, "start %d%c", &number,  &c) == 1) {

note: above formats (and yours) not check there 1 space between "start" , number. if string "start \t 45" if return true

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
