C ++ - function overloading

• C ++ allows multiple functions with the same name, as long as they can be different parameter list, which is overloaded function
• Reload function can make a variety of uses
• Parameter Type list, the number of parameters, parameter order, as long as there is a list of the different parameters of different called
• Function overloading is just the syntax level, in essence, they are still different functions, occupy different memory, different entry address
• Too few parameters or function overloading ambiguity problem may occur when too much, and that is the compiler does not know which function prototype match
