Benifits of function overloading in c++ program?

Question

why we need function overloading in c++ ? or what are the benifits of function overloading in c++ program?

Answer 1

@Jonathan _ answer is sound and clear, you should keep what he said in mind

A little more technical but you ABSOLUTELY NEED function overloading with variadic templates. I will not explain them here because they are quite complex. If you want an explanation about them,ask and I'll tell you but just know that you need a good understanding of classical templates to start learning variadic ones

Answer 2

If you want to create a function to add a e.g. Date, you can overload a function addDate(Date date), and another one addDate(int day, int month, in year)

This way you can either add a date-struct or the date by single values.
