You are writing a program. Give the necessary statements to open a file and to confirm that the file has been successfully opened for writing. Important: Why bother to test?

What will be an ideal response?

```
#include
#include //unnecessary, fstream gets this
#include //for exit(int)
int main()
{
using std::ifstream;
using std::cout;

ifstream inStream;
inStream.open("myFile.txt";);
if (inStream.fail())
{
cout << "Input file failed to open\n";
exit(1);
}
}
```
