Answer 2

Answer:

The correct answers are as follows:

a) option(iii)

b) option (ii)

c) option (i)

d) option (ii)

e) option (iv)

f) option (iii)

g) option (iv)

h) option (i)

i) option (iii)

j) option (ii)

Explanation:

a) Void data type is used to represent the absence of parameters.

b) Int f (float) can be defined as f is a function taking an argument of type float and returning an integer.

c) When a language has the capability to produce new data types mean, it can be called as overloaded

d) Function overloading is also similar to constructor overloading.

e)  while using pass by reference following things happen:

• The values of those variables are passed to the function so that it can
• manipulate them
• The location of the variable in memory is passed to the function so that it can use the same memory area for its processing
• The function declaration should contain an ampersand (and in its type declaration)

f) catch keyword is used to handle the exception.

g) None of the mentioned statements is correct.

h) The string are stored in the Contiguous memory.

i) Derived class does not inherit operator = () members from the base class.

j) postfix operator is having the highest precedence
