2nd PUC Computer Science Function Overloading Two Mark Questions and Answers<\/h3>\n

Question 1.
\nWhat is meant by overloading implements polymorphism?
\nAnswer:
\nThe overloading helps to apply polymorphism because Function overloading means two or more functions having same name but different types of arguments or different number of arguments.

    \n
  • The parameters\/arguments should differ in the number of arguments or if they have same number of argument then they should differ in the type of the arguments<\/li>\n
  • The use of typedef keyword for naming functions is not treated as different type but is only a synonym for another type.<\/li>\n<\/ul>\n

    Question 4.
    \nWhat are inline functions? Give an example.
    \nAnswer:
    \nInline functions are those functions whose body is inserted in place of the function call.

          \n
        1. The overloading function helps to reduce the use of different names for many functions.<\/li>\n
        2. The developer of the program can use one function name to give function call to one in many functions. This reduce the selecting a function block to give a function call by the user.<\/li>\n
        3. It is easier to understand the flow of information that helps in faster debug.<\/li>\n

                  2nd PUC Computer Science Function Overloading five Mark Questions and Answers<\/h3>\n

                  Question 1.
                  \nExplain the need for function overloading.
                  \nAnswer:
                  \nThe overloading helps to apply polymorphism because Function overloading means two or more functions having same name but different types of arguments or different number of arguments. Whereas polymorphism refers to “one name having many forms of an object behavior depending on situations.<\/p>\n

                  Function overloading is normally used when several function of the same name perform identical tasks on different data types. The overloading function helps to reduce the use of different names for many functions.<\/p>\n

                  The developer of the program can use one function name to give function call to one in many functions and C++ select the appropriate function by checking the number of parameter and type of parameters. This reduces the selecting a function block to give a function call by the user.<\/p>\n

                  It is easier to understand the flow of information that helps in faster debug. Easy program maintenance. There can be common interface between programs and real-world objects.<\/p>\n

                  \n}
                  \nThe definition of inline function should be defined before all functions that call it.
                  \nThe function definition should have the prefix inline.
                  \nExample:
                  \n\"2nd<\/p>\n

                  Question 4.
                  \nExplain friend functions and their characteristics.
                  \nAnswer:
                  \nA friend function is a non-member function and is a friend of a class. It is declared inside a class with the prefix friend and defined outside the class like any other normal function without the prefix friend. This friend function can access private and protected data members if it is a friend function of that class.
                  \nThe characteristics of friend function are<\/p>\n

                    \n
                  • The friend function should not be defined inside the class.<\/li>\n
                  • It can be declared inside a class under public, private or protected access specifier since it is a non member function and make no difference.<\/li>\n
                  • A friend function should be defined outside the class without prefix friend<\/li>\n
                  • The scope resolution operator should not be used while defining the friends function outside the class since it is not member function of any class.<\/li>\n
                  • It should be called like any other normal function and not to be called using an object with dot operator.<\/li>\n
                  • The data members of class are accessed through object and dot operator with a data members.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
