Illustrating the generic lexicographical_compare algorithm
#include <iostream>
#include <cassert>
#include <algorithm>
#include <vector>
using namespace std;
int main()
{
string s("helio");
string s2("hello");
vector<char> vector1(s.begin(), s.end());
vector<char> vector2(s.begin(), s.end());
// Show that vector1 is lexicographically less than vector2:
bool result = lexicographical_compare(vector1.begin(),vector1.end(), vector2.begin(), vector2.end());
cout << result;
return 0;
}0
Use std::lexicographical_compare to compare two char arrays
#include <iostream>
using std::cout;
using std::endl;
#include <algorithm>
#include <vector>
#include <iterator>
int main()
{
char c1[ 10 ] = "HELLO";
char c2[ 10 ] = "BYE BYE";
// perform lexicographical comparison of c1 and c2
bool result = std::lexicographical_compare( c1, c1 + 10, c2, c2 + 10 );
cout << c1 << ( result ? " is less than " :
" is greater than or equal to " ) << c2 << endl;
return 0;
}HELLO is greater than or equal to BYE BYE
