Char** to std::vector<std::string>

Oct 2, 2009 at 4:21pm

Hello,

I was googling without success to find the "canonical" way to transfer values from char** to std::vector<std::string>.

Could help?

A string can be constructed with a C string and a vector can be constructed by iterators ( as pointers )
Example:

1
2
3

char **someCstrings;
int numberOfCstrings;
std::vector<std::string> myvector ( someCstrings, someCstrings+numberOfCstrings); // constructor

Thanks Bazzy,

But... Is there also a way to know the numberOfCstrings before the call of the std::vector constructor ?

Not really, when you have an array in a pointer you should know the size of it
