Tring to convert str string for use in std :: getline delimiter

Question

im trying to take the value of std::string and use it as a separator in std::getline() but there is no mater, what am I doing, the compiler gives me an error. this is what i am trying to do:

 std::stringstream ss(s); std::string item; std::string delim ="&&="; int ssize = delim.size(); int newssize = ssize+1; char del[SSIZE]; // also here when i try gives error strcpy(del,delim.c_str()); char * delrr[1024] = delim.c_str(); //gives error while(std::getline(ss,item,delrr)) { elems.push_back(item); } 

the im get error is always related to the const char * conversion.

Answer 1

The third argument to getline () is a character, not an array of characters. Watch this . You cannot use this function if you need multiple delimiters or a multiple character delimiter.

Use find () and substr ().

Answer 2

std :: string :: c_str () gives you a pointer to an array of characters. To populate an array of characters with the results of a call to c_str() , you need to use strcpy() or strncpy() , since they actually copy the C style string.

Also, you declared delrr as an array of 1024 characters, not 1024 characters, is that really the intention?
