c++ - I am unable to store string into an array, which i then want to use for comparison -

i unable store string array, when output b[c] nothing appears whatsoever, how can store array?

int main(int argc, char *argv[]) {     string b[80000];     int c=0;     string s;     ifstream file(argv[1]);      while(file >> s) {         b[c]=s;         c++;         cout<<b[c];     }      system("pause");     return 0; } 

you're printing empty strings. move cout << b[c]; before c++;

i'd suggest use std::vector, avoid unnecessary temporary variables , magic constants:

#include <iostream> #include <vector> #include <string> #include <fstream>  int main(int argc, const char* argv[]) {     std::ifstream fin(argv[1]);      std::vector<std::string> v     {         std::istream_iterator<std::string>(fin),         std::istream_iterator<std::string>()     };      for(const auto& elem: v)         std::cout << elem << std::endl;      return 0; } 

don't forget handle cases when file name isn't passed, or file doesn't exist.
