I am trying to read a list of words from a file example.txt and sort the list and rewrite the sorted list to the file. So far I am able to read and sort the list but am unable to rewrite the sorted list to the file. Also the last entry is read twice how do I avoid this? C++

1 #include 2 #include 3 #include 4 #include 5 #include 7 using namespace std; 9 int main() I/create fstream instance and open file "example.txt" 2 fstream sf 3 sf.open("example.txt", fstream::out 2 fstream::in); 5 if(sf.is_open )) cout word; //cout
