#include
#include
using namespace std;
const int SIZE = 6;
int main()
{
char stringValue[ SIZE ];
int sum = 0;
for ( int i = 1; i <= 4; ++i )
{
cout << "Enter an integer string: ";
cin >> stringValue;
sum += atoi( stringValue ); // add converted stringValue to sum
} // end for
cout << "The total of the values is " << sum << endl;
return 0;
} // end main
```
Enter an integer string: 11
Enter an integer string: 22
Enter an integer string: 44
Enter an integer string: 88
The total of the values is 165
