Whenever we have used the method or function it will be called the main() method it must be used for creating the instance in the heap memory. The function declaration and the definition will be the standard type of protocols and it brings all the types of members and the functions are calculated into the current and future scopes. Normally the C++ declarations and the directives are used with some kind of memory spaces allocated for the functions to store it in the RAM. It depends upon the data types and the object creation sizes must be calculated and it allocates the memory space for both the big storage data type variables as well as small amount storage variables. It also makes it easier to write the programming codes and clean it up using the same methods like destroying () or any other default methods belonging to the garbage collections and it’s the main area for destroying the unwanted codes and clean up the memory space areas. The C++ having n number of reserved keywords, functions that will provide some level of abstractions from the actual namespaces as well as the new libraries which is being already used for the programmers to allow it with more focus on the coding concepts. In the above codes, we have function name () that function is declared using some arguments but in the main method, the function is called without arguments so when compiles the code it creates the undefined reference error. The undefined reference is one of the predefined errors from the functions and it is used to call whenever the format of the method linked not correctly to the object creation of the codes. Based on the requirements we will utilize the special keywords, variables, data types, and functions from the programming libraries. In C++ each object, variables, keywords, and functions have their own syntax and attributes for declaring in the programming codes.
