Answer:
The answer is "Option b"
Explanation:
In the given code three-class C1, C2, and C3 are declared, in which C2 and C3 extend the class C1. In the next line, C2 and C3 object are created, that is c2 and c3. and in the last line c2 class object holds two-class C2, C1, and one object c3 value, this code will give runtime error because it can't cast object from sibling class, and wrong choices can be defined as follows:
- In option a, It is not correct because it can't cast c3 object into c2 object.
- In option c, It is not correct because it performs multiple casting in nested forms.
- In option d, It is wrong because the statement is not correct.
Answer:
modulation
Explanation:
Modulation is the procedure of encoding data into electrical signals for transmission through a media. For transmission, binary information, denoted by a sequence of ones and zeros, should be translated to analog or digital electrical signals. The method converts data into electrical signals suited for transmission is known as modulation. Digital modulation is the transmission of binary signals zeroes and ones.
