How can we read data from a file into an array
// This program reads data from a file into an array.
#include <iostream>
#include <fstream> // To use ifstream
#include <vector>
using namespace std;
int main()
{
std::vector<int> numbers;
ifstream inputFile("c.txt"); // Input file stream object
// Check if exists and then open the file.
if (inputFile.good()) {
// Push items into a vector
int current_number = 0;
while (inputFile >> current_number){
numbers.push_back(current_number);
}
// Close the file.
inputFile.close();
// Display the numbers read:
cout << "The numbers are: ";
for (int count = 0; count < numbers.size(); count++){
cout << numbers[count] << " ";
}
cout << endl;
}else {
cout << "Error!";
_exit(0);
}
return 0;
}
