hello world, files and Interactions

This the first lab of many with an introduction back into C++ programming.
It has the basic input output using IOStream as well as reading in and out of a file.


#include <iostream>
#include <fstream>

using namespace std;

void example4();
void exampleFiles();

int main()
 {
 exampleFiles();
 cout << "enter an int to finish";
 int x;
 cin >> x;
 return 0;
}

void exampleFiles()
{
 int number;
 char ch;
 float fl;
 fstream myFile("output.txt", ios::out | ios::in | ios::app);
 cout << "enter a integer" << "\n";
 cin >> number;
 myFile << "You have entered the number " << number << "\n";
 cout << "Enter a character" << "\n";
 cin >> ch;
 myFile << "you entered " << ch << "\n";
 cout << "Enter a float" << "\n";
 cin >> fl;
 myFile << "you entered " << fl << "\n\n";
 fstream myInputFile("input.txt", ios::out | ios::in | ios::app);
 myInputFile >> number;
 myInputFile >> ch;
 myInputFile >> fl;
 std::cout << "in Summary you have entered " <<number << ", " << ch << " & " <<fl << "\n";
 myFile.close();
 myInputFile.close();
}

void example4()
{
 int number;
 char ch;
 float fl;
 cout << "Enter a integer" << "\n";
 cin >> number;
 cout << "You have entered the number " << number << "\n\n";
 cout << "Enter a character" << "\n";
 cin >> ch;
 cout << "you entered " << ch << "\n\n";
 cout << "Enter a float" << "\n";
 cin >> fl;
 cout << "you entered " << fl << "\n\n";
 std::cout << "in Summary you have entered " <<number << ", " << ch << " & " <<fl << "\n";
