Which of the following statements are correct about the C#.NET code snippet given below?
namespace IndiabixConsoleApplication
{
class index
{
protected int count;
public index()
{
count = 0;
}
}
class index1: index
{
public void increment()
{
count = count +1;
}
}
class MyProgram
{
static void Main(string[] args)
{
index1 i = new index1();
i.increment();
}
}
}
1/ Count should be declared as public if it is to become available in the inheritance chain.
2/ Count should be declared as protected if it is to become available in the inheritance chain.
3/ While constructing an object referred to by i firstly constructor of index class will be called followed by constructor of index1 class.
4/ Constructor of index class does not get inherited in index1 class.
5/ Count should be declared as Friend if it is to become available in the inheritance chain.
