Suppose that a text file text.txt contains an unspecified number of scores. Write a program that reads the scores from the file and displays their total and average. Scores are separated by blanks.

Question

What will be an ideal response?

Answer 1

```
#include
#include
using namespace std;

int main()
{
ifstream input;

// Open a file
input.open("Exercise13_1.txt");

if (input.fail())
{
cout << "File does not exist" << endl;
cout << "Exit program" << endl;
return 0;
}

int number = 0;
int total = 0;

while (!input.eof()) // Continue if not end of file
{
input >> number;
total += number;
}

input.close();

cout << "total is " << total << endl;
return 0;
}
```
