visual c++ - C++ file input, stream, and compile -


so problem i'm getting error c3867 when i'm attempting close file stream (at least that's hope i'm doing). intent make program uses input file read in values array , there determine highest , lowest numbers of array are. arraysize can less or more 10 data items, , must check file open errors before reading data file , close file after finished reading elements array. can later it's instruction anyway. 

#include <stdafx.h> #include <iostream> #include <fstream> #include <string> using namespace std;  int main(){     const int arraysize = 10;     float numbers[arraysize];     int count = 0;     string filename;     float high, low;      fstream inputfile(filename, ios::in);      cout << "what filename wish use? ";     cin >> filename;      inputfile.open(filename);     while (count < arraysize && inputfile >> numbers[count])         count++;     inputfile.close;      high = numbers[0];     low = numbers[0];      (int = 0; < arraysize; i++){         if (numbers[i] > high)             high = numbers[i];         if (numbers[i] < low)             low = numbers[i];     }      cout << "the highest number in file is: " << high;     cout << "the lowest number in file is: " << low;      return 0; }

am missing anything?

you need call inputfile.close() function parentheses.
