Returns an iterator past the last element of*this.
This returned iterator only acts as a sentinel. It is not guaranteed to bedereferenceable.

[edit]Return value
Iterator past the last element.
[edit]Complexity
Constant.
Notes
libc++ backportscend() to C++98 mode.
[edit]Example
Run this code
#include <algorithm>#include <cassert>#include <cstddef>#include <iostream>#include <map>#include <string> int main(){auto show_node=[](constauto& node,char ending='\n'){std::cout<<"{ "<< node.first<<", "<< node.second<<" }"<< ending;}; std::multimap<std::size_t,std::string> mmap;assert(mmap.begin()== mmap.end());// OKassert(mmap.cbegin()== mmap.cend());// OK mmap.insert({ sizeof(long),"LONG"}); show_node(*(mmap.cbegin()));assert(mmap.begin()!= mmap.end());// OKassert(mmap.cbegin()!= mmap.cend());// OK mmap.begin()->second="long"; show_node(*(mmap.cbegin())); mmap.insert({ sizeof(int),"int"}); show_node(*mmap.cbegin()); mmap.insert({ sizeof(short),"short"}); show_node(*mmap.cbegin()); mmap.insert({ sizeof(char),"char"}); show_node(*mmap.cbegin()); mmap.insert({{ sizeof(float),"float"},{ sizeof(double),"double"}}); std::cout<<"mmap = { ";std::for_each(mmap.cbegin(), mmap.cend(),[&](constauto& n){ show_node(n,' ');});std::cout<<"};\n";}
Possible output:
{ 8, LONG }{ 8, long }{ 4, int }{ 2, short }{ 1, char }mmap = { { 1, char } { 2, short } { 4, int } { 4, float } { 8, long } { 8, double } };[edit]See also
