Output a string with copy function
#include <algorithm>
#include <iostream>
#include <iterator>
#include <string>
#include <vector>
using namespace std;
int main( )
{
string s( "this is a test." );
cout << s << endl;
copy( s.begin(), s.end(), ostream_iterator<char>( cout, " " ) );
}
Read string in and then output
#include <iostream>
#include <string>
using namespace std;
int main()
{
string string1;
string string2;
cout << "\nEnter a string: ";
getline( cin, string1 );
cout << "Enter a second string: ";
getline( cin, string2 );
cout << "\nFirst string: " << string1 << endl;
cout << "Second string: " << string2 << endl;
cout << endl;
return 0;
}
Use of as istream_iterator iterator
#include <iostream>
#include <algorithm>
#include <string>
using namespace std;
int main()
{
string words[5] = { "ABCD", "BCDEF", "CERF","DERT", "EFRE"};
string* where;
where = find(words, words + 5, "CD");
cout << *++where << endl;
sort(words, words + 5);
where = find(words, words + 5, "ER");
cout << *++where << endl;
}
