c++ - Templates. adding , getting element char* -

i've got problem template class , using char*. storage elements in class , try add or element ,but segmentation fault appear. possible without class specialisation type char* ?

edit 1: let's assume can't change code in main function class , methods, without specialisations. possible handle char* ? ;)

#include <iostream> #include <vector> using namespace std;  template<class t> class test { public:     void additem(t element){         elements.push_back(element);     }      t getitem(int i){         return elements[i];     }      vector<t> elements; };  int main() {     char * cpt[]={"tab","tab2","tab3"};     test<char*> test1;     test1.additem(cpt[1]);     char * item=test1.getitem(0);     //segmentation fault     // done without specialisation class char*    ?     item[0]='z';     cout<<item<<endl;     for(auto v:test1.elements) cout<<v<<endl;     return 0; } 

my code

you're trying modify constant string literal. gives undefined behaviour; typically segmentation fault, if literal stored in write-protected memory.

in modern c++, program shouldn't compile, since deprecated conversion string literal non-const char* forbidden in c++11.

if want store modifiable strings, you're best off std::string.
