i'm trying to get the last word of the sentence using strtok.. i tried this :
while (tok != NULL)
{
tok = strtok (NULL, " ");
if((tok != NULL) && (strtok(NULL, " ")==NULL))
printf("%s", tok);
}kinda doesn't work... anyone knows why?
Yes, tok is a char * pointer..
Jump to Post>>anyone knows why?
Yes.how about something like this:
char* lastWord = NULL; while( tok != NULL ) { lastWord = tok; tok = strtok(NULL, " "); } printf("%s\n", lastWord);
Jump to Postyou might have to add code to bypass all other white space (spaces and tabs) because I don't think strtok will do that. Example:
"No is the time "
>>anyone knows why?
Yes.
how about something like this:
char* lastWord = NULL;
while( tok != NULL )
{
lastWord = tok;
tok = strtok(NULL, " ");
}
printf("%s\n", lastWord);thanks!
that looks like an obvious solution now...

[edit] AD solved that problem already [/edit]
Anyway, if you're using C++, why not use std::strings, find() and substr()?
Demo:
#include <iostream>
#include <string>
int main ()
{
std::string str = "This is a line of text";
int lastspace= str.find_last_of(' ') ;
std::cout << str.substr(lastspace+1 ,str.size()-lastspace ) << "\n";
return 0;
}output: text
but that doesn't work when there is trailing white space. need to add a little code to trim trailing white space.
Yes you're right of course
