Method \/<\/strong> Function<\/strong><\/a> overloading means more than one functions <\/a> with same name with different arguments<\/a> for different purpose in a program.<\/strong><\/p>\n\n\n\n

Method \/ Function overloading is an example of polymorphism.<\/a><\/p>\n\n\n\n

Using no argument no return value function overloading can’t be done.<\/p>\n\n\n\n

Example<\/p>\n\n\n\n

Method \/ Function Overriding :-<\/strong><\/h3>\n\n\n\n
When base class and derived class contains the method of same signature then this term is known as method overriding.<\/strong><\/p>\n\n\n\n
Same signature means every this is same i. Method name, arguments, types, etc.<\/p>\n\n\n\n
when we call the method using object of derived class then method of base class is overridden.<\/p>\n\n\n\n
example.<\/p>\n\n\n\n
\n
class nips<\/p>\n\n\n\n
{<\/p>\n\n\n\n
public:<\/p>\n\n\n\n
void show(int x,int y)<\/p>\n\n\n\n
