Sorting With the sort() Algorithm

Sorting With the sort() Algorithm

The generic algorithm sort() is part of the Standard Library. sort() takes two arguments of type const iterator that point to the beginning and the end of the sequence respectively:

 #include #include  //definition of sort()#include using namespace std;void main(){  vector  vi;  vi.push_back(7);   vi.push_back(1);  vi.push_back(19);  sort(vi.begin(), vi.end() );   // sort vi; default is ascending order  cout

When a descending order is preferred, you can use reverse iterators:

 sort(vi.rbegin(), vi.rend() ); // now sort in descending order cout
