regex - regex_search C++ not matching substrings -

this question has answer here:

• is gcc 4.8 or earlier buggy regular expressions? 3 answers

regex_search not matching "ter" in "computer computer" when i'm using following code -

#include <iostream> #include <regex>  using namespace std;  int main() {     string str("computer computer");     cout << regex_search(str, regex("ter"));     return 0; } 

the above code gives me 0, whereas there "ter" in subject. going on here. know php's regex matches substring fine, whats wrong here?

i'm using c++11 gcc, problem since read somewhere has poor support regex.

it reruns 1 type bool, means pattern match found in word .run program.

#include <stdio.h> #include<iostream> #include <regex> using namespace std; int main(void) {     cout << regex_search(string("computer computer"), regex("ter"));//1     cout << regex_search(string("computer computer"), regex("tesdsr"));//0     return 0; }
