How do I convert from std  stringstream to std  string in C     Do I need to call a method on the string stream

User · Answer

Use the  str  -method      Manages the contents of the underlying string object       1  Returns a copy of the underlying string as if by calling rdbuf  - gt str         2  Replaces the contents of the underlying string as if by calling rdbuf  - gt str new str          Notes      The copy of the underlying string returned by str is a temporary object that will be destructed at the end of the expression  so directly calling c str   on the result of str    for example in auto  ptr   out str   c str     results in a dangling pointer
