In perl, I can do the following thing to split a string.

my ($benchmark, $suffix) = split(/./, $fullbenchmarks);

I'm wondering if there is similar thing in C++ which can do the same
thing. Would you please tell me if you know it?

Thanks,
Peng

A partial solution would be:

inline bool space(char c){
return std::isspace(c);
}

inline bool notspace(char c){
return !std::isspace(c);
}

//break a sentence into words
std::vector<std::string> split(const std::string& s){
typedef std::string::const_iterator iter;
std::vector<std::string> ret;
iter i = s.begin();
while(i!=s.end()){
i = std::find_if(i, s.end(), notspace); // find the beginning of a
word
iter j= std::find_if(i, s.end(), space); // find the end of the same
word
if(i!=s.end()){
ret.push_back(std::string(i, j)); //insert the word into vector
i = j; // repeat 1,2,3 on the rest of the line.
}

}
return ret;
}
