What will be the output of the following C++ code?
#include <iostream>
using namespace std;
class bowl
{
public:
int apples;
int oranges;
};
int count_fruit(bowl * begin, bowl * end, int bowl :: *fruit)
{
int count = 0;
for (bowl * iterator = begin; iterator != end; ++ iterator)
count += iterator ->* fruit;
return count;
}
int main()
{
bowl bowls[2] = {{ 1, 2 },{ 3, 5 }};
cout << "I have " << count_fruit(bowls, bowls + 2, & bowl :: apples) << " apples\n";
cout << "I have " << count_fruit(bowls, bowls + 2, & bowl :: oranges) << " oranges\n";
return 0;
}
#include <iostream>
using namespace std;
class bowl
{
public:
int apples;
int oranges;
};
int count_fruit(bowl * begin, bowl * end, int bowl :: *fruit)
{
int count = 0;
for (bowl * iterator = begin; iterator != end; ++ iterator)
count += iterator ->* fruit;
return count;
}
int main()
{
bowl bowls[2] = {{ 1, 2 },{ 3, 5 }};
cout << "I have " << count_fruit(bowls, bowls + 2, & bowl :: apples) << " apples\n";
cout << "I have " << count_fruit(bowls, bowls + 2, & bowl :: oranges) << " oranges\n";
return 0;
