yesterday i had a written exam of asp.net developer job. in this exam i saw a question in which there are three classes X,Y,Z and z class inherit by Y and Y class inherit by X. and the code is following:-

public void class X
{
class X()
{
consol.write("classX");
}
}
public void class Y : X
{
class Y()
{
consol.write("classY");
}
}
public void class Z : Y
{
class Z()
{
consol.write("classZ");
}
}

main()
{
class Z obj = new Z();
}
