read word by word from file in C++

Question

this function should read a file word by word and it does work till the last word, where the run stops

void readFile(  ) {     ifstream file;     file.open ("program.txt");     string word;     char x ;     word.clear();      while ( ! file.eof() )     {         x = file.get();          while ( x != ' ' )         {             word = word + x;             x = file.get();         }              cout<< word <<endl;             word.clear();      } } 

any one see what is the problem and how it can be solved??

Answer 1

First of all, don't loop while (!eof()), it will not work as you expect it to because the eofbit will not be set until after a failed read due to end of file.

Secondly, the normal input operator >> separates on whitespace and so can be used to read "words":

std::string word; while (file >> word) {     ... }
