I am getting an undefined reference error. I've stared at this code for about an hour trying to figure it out. This is the error I get.
undefined reference to fileToArray(std::basic_fstream<char, std::char_traits<char> >&, int*, int)
This is my code.
#include <iostream>
#include <fstream>
#include <string>
#include <cctype>
#include <cstring>
using namespace std;
void arrayToFile(fstream&, int*, int);
void fileToArray(fstream&, int*, int);
int main()
{
fstream dataFile;
int numInt; //Size of array
int* numArray; //Array to hold integers
int num; //Integer for user to input into array.
cout << "Enter the number of integers you would like to put inside of an array: ";
cin >> numInt;
numArray = new int[numInt];
cout << "\nFill in the array with integers";
for (int i = 0; i < numInt; i++)
{
cout << "Enter integer for position " << i << ": ";
cin >> num;
numArray[i] = num;
}
arrayToFile(dataFile, numArray, numInt);
fileToArray(dataFile, numArray, numInt);
cout << "Contents of numArray" << endl;
for (int i = 0; i < numInt; i++)
{
cout << numArray[i] << " ";
}
delete [] numArray;
return 0;
}
