c++ - Should I delete a heap-allocated string after sending it to std::string? -
say have this:
char * p = new char[10]; std::string str = p;
do have delete[]
p
or std::string
me?
do have delete[] p or std::string me?
no doesn't generally, each new
must paired delete
. so,
char * p = new char[10]; /* put buffer */ std::string str = p; /* stuff */ delete [] p;
but wouldn't need if created array on stack:
{ char p[10]; /* put buffer */ std::string str = p; // delete [] p; // no delete required }
