storing a c++ string into a char* vector -

i'm trying store string vector of pointers. starting point of code. vector store words user types in , either add vector if vector doesn't have or show word in vector.

i tried use strcpy() told me use strcpy_s(). did , crashes every time no error. can give me insight going on here.

vector<char*> wordbank;  string str; cin >> str;  wordbank[0] = new char[str.length() + 1]; strcpy_s(wordbank[0], str.length() + 1 , str.c_str() );  cout << wordbank[0];  delete[] wordbank[0]; 

i not consider vector<char*> wordbank; c++ code, rather c code happens use c++ features.

the standard library in c++ can make life easier. should use std::vector<std::string> instead.

vector<string> wordbank; wordbank.push_back(str); 

it avoid pointer stuff, need not memory management (which reason rid of pointers).

for strcpy_s, it's safer version of strcpy, because have explicitly specify size of target buffer, can avoid buffer overflows during copies.

however, strcpy_s non-standard , ms specific, never use strcpy_s unless want code compiled on msvs. use std::copy instead.
