Explanation / Answer

2. Let data be an array of int type, with size or capacity = 5. The value of data[3] after the following code executes is _____. data[0] = 2; for (int i = 1; i < 5; i++) data[i] = data[i-1] + i;

Ans) 8

3.3. What is the result of 32 % 3?

Ans) 2

Reason: modulus operation take the remainder after division.

4.4. A return statement causes execution of a function or method to _____.

Ans) terminate and return to where the function or method was called

5.5. Consider the C++ class declaration class Circle { private: double radius; public: Circle(); Circle(double); void setRadius(double); double getRadius(); double volume(); void print(); }; How many constructors does the class have?

Ans) 2

reason: One cconstructor is having no arguments and other constructor is having double as arguement.

public: Circle();

Circle(double);

Question 6.6. The value of variable y after the following switch statement executes is _____.

Ans) 7

Reason: As the value of y =2 the case 2 will be executed so the statement y+=2; will be executed.

so y=2+2=4.

As case 2 is not having break statement the next case (Case 3) will also executed.

so the statement y+=3 will be executed.so y=4+3=7

As the case 3 is having break then control come out of the switch case.

So finally the value of y=7

7.7. Consider the Java class class MyNumberClass { private int number; public MyNumberClass() { number = 0; } public MyNumberClass(int n) { setNumber(n); } public void setNumber(int n) { number = n; } public int getNumber() { return number; } public int getSuccessor() { return number+1; } public int getPredecessor() { return number-1; } public void print() { System.out.println(number); } } What will the code below print? MyNumberClass x = new MyNumberClass(5); x.setNumber(x.getSuccessor() + x.getPredecessor()); x.print();

Ans) 10
