Functions

[A].Member function of class
[B].main()[C].Member function of structure
[D].Both B and C

Answer: Option B

Question: Which of the following function / type of function cannot be overloaded?
[A].Member function
[B].Static function[C].Virtual function
[D].Both B and C

Answer: Option C

[A]. Only one parameter of a function can be a default parameter.
[B]. Minimum one parameter of a function must be a default parameter.[C]. All the parameters of a function can be default parameters.
[D]. No parameter of a function can be default.

Answer: Option C

[A]. The order of the default argument will be right to left.
[B]. The order of the default argument will be left to right.[C]. The order of the default argument will be alternate.
[D]. The order of the default argument will be random.

Answer: Option A

[A]. Default arguments can be provided for pointers to functions.
[B]. A function can have all its arguments as default.[C]. Default argument cannot be provided for pointers to functions.
[D]. A default argument cannot be redefined in later declaration.

Answer: Option C

[A]. int Sum(int a, int b = 2, int c = 3);
[B]. int Sum(int a = 5, int b);[C]. int Sum(int a = 0, int b, int c = 3);
[D]. Both B and C are incorrect.

Answer: Option D

[A]. A default argument is checked for type at the time of declaration and evaluated at the time of call.
[B]. We can provide a default value to a particular argument in the middle of an argument list.[C]. We cannot provide a default value to a particular argument in the middle of an argument list.
[D]. Default arguments are useful in situations where some arguments always have the same value.

Answer: Option B

Question: Which of the following statement is correct?
[A]. The default value for an argument cannot be function call.
[B]. C++ allows the redefinition of a default parameter.[C]. Both A and B.
[D]. C++ does not allow the redefinition of a default parameter.

Answer: Option D

 

[A]. int Function(int Tmp = Show());
[B]. float Function(int Tmp = Show(int, float));[C]. Both A and B.
[D]. float = Show(int, float) Function(Tmp);

Answer: Option A

 

[A]. The default value for an argument can be a global constant.
[B]. The default arguments are given in the function prototype.[C]. Compiler uses the prototype information to build a call, not the function definition.
[D]. The default arguments are given in the function prototype and should be repeated in the function definition.

Answer: Option D
