The standard facets suitable for use with std: : wstring_ convert are std: : codecvt_ utf8 for UTF. Std string assignment. A trivial copy assignment operator makes a copy of the object representation as if by std: : memmove.
S Pointer to a null- terminated sequence of characters. Class template std: : wstring_ convert performs conversions between byte string std: : string wide string std: : basic_ string < Elem > using an individual code conversion facet Codecvt. = can also be written < >, but this is an obsolete usage kept for backwards compatibility only. The name follows the tradition of naming language versions by the publication year of the specification, though it was formerly named C+ + 0x because it was. The ANSI C+ + GNU string classes included in the C+ + standard library attempt to simplify string manipulation by automating much of the memory allocation and management. New code should always use!
The assignment operation between unique_ ptr objects that point to different types ( 3) needs to be between types whose pointers are implicitly convertible shall not involve arrays in any case ( the third signature is not part of the array specialization of unique_ ptr). Std: : wstring_ convert assumes ownership of the conversion facet cannot use a facet managed by a locale. All data types compatible with the C language ( POD types) are trivially copy- assignable. 2 [ m] Status: ready Submitter: Richard Smith Date: According to 12.
Std string assignment. The reason Herb said what he said is because of cases like this.
If the deleter_ type is a reference type, the deleter object is copied ( instead of moved). Purpose The purpose of this C+ + 11 FAQ is To give an overview of the new facilities ( language features and standard libraries) offered by C+ + 11 in addition to what is provided by the previous version of. That is, C is an implementation detail.
And A passes a string through B and into C. 2 [ m] paragraph 25 If a standard- layout class object has any non- static data members its address is the same as. A does not know or care about C; all A knows about is B.
Let' s say I have function A which calls function B, which calls function C. It was approved by International Organization for Standardization ( ISO) on 12 August superseded by C+ + 14 on 18 August , later, replacing C+ + 03 by C+ + 17.

C+ + may use the C char variable type string functions but they rely on a null termination proper memory allocation to hold the string. Parameters str A string object moved ( 5) if different from * this ( if moved, whose value is either copied ( 1) str is left in an unspecified but valid state).
As it' s currently written, it’ s hard to tell exactly what you' re asking. Assigns a new value to the string, replacing its current contents.
( See member function assign for additional assignment options).
