The code will compile and run and the letter "A" will be written to the standard ouput
C -
The code will not compile because the switch statement does not have legal expression
D -

10-
1. class Test{
2 public static void Main(){
3. int i=0;
4. char c= ’s’;
5. object [ ] objArray=new object[3];
6. objArray[0] = new object();
7. objArray[0] = I;
8. objArray[0] = c; //new char();
9. }
10. }
The above code is compiled and run . The possible error is:
A -
The code will generate a compile time error at lines 7 and 8 as the arrasy can have only one type of data
B -
The code will generate a compile time error at lines 7 and 8 as the implicit conversion of int and char to a object type is not possible
