Analyzing the following code:
class test
{ public static void main(string args[])
{ nclass nc = new nclass();
nc. t = nc. t++;
}
}
class foo
{ int t;
private nclass()
{ }
}

the program has a compilation error because the nclass class has a private constructor.
the program does not compile because the parameter list of the main method is wrong.
the program compiles, but has a runtime error because t has no initial value.
the program compiles and runs fine.
