The C language provides several standard library functions that convert numbers of any type (integer, long, float, and so on) to a string. The following is an example of converting an integer to a string using the Itoa () function:# include #

Dynamic polymorphism in C + + is achieved through virtual functions. Static polymorphism is implemented by overloading the function, an early binding before the program runs, and dynamic polymorphism is a post-binding in the process of running the
