Read data from file into arrays in c++ 2011

Code:

#include <iostream> #include <fstream> #include <string> #include <iomanip> #include <cmath> #include <ctime> using namespace std; const string AUTHOR = "Rf"; const string ROLE = ", (s)\n"; const string SOLTXT = "\nSolution by "; const string INFILE_ERR_MSG = "File does not exist or it is empty!\n"; const int EXIT_ERR_INFILE = -1; // Error with input file const int MAX_INT = 500; bool openFileForInput(ifstream&); int main() { ofstream outData("INTEGERS.TXT"); time_t t; time(&t); srand (t); int base = -250; int num; for (int i = 0; i < MAX_INT; i++) { outData << (num = base + rand()%500) << endl; } outData.close(); ifstream inData; // Open a file for input // Check for existence of file in current directory // If file exists, is there any data in the file if (!openFileForInput(inData)) { cout << INFILE_ERR_MSG; system("PAUSE"); return EXIT_ERR_INFILE; } cout << endl << endl; system ("PAUSE"); return 0; } bool openFileForInput(ifstream& inp) { char check; inp.open("INTEGERS.TXT"); // See if we can open check = inp.peek(); // Determine whether file is not empty if (inp && !inp.eof() ) // checks if the file exists and not empty return true; return false; } /* End of openFileForInput() */ bool getNum(ifstream& inp, ofstream& otp)// this is where I'm stuck { int num; unsigned int neg[]; int posEven[]; int posOdd[] inp >> num; if (inp && !inp.eof()) { cin >> inp >> int posEven[num] return true; } return false; }
