Join Bill Weinman for an in-depth discussion in this video Overloading function names, part of C++ Essential Training.
- [Instructor] In C++, it's possible…to have different functions with the same name.…The compiler selects which function to called based…on the entire function signature,…not just the function name.…This behavior is different than in C,…where each function must have a unique name.…Here I have a working copy of func-overload.cpp…from chapter five of the exercise files.…In C++, the function signature consists of the return type,…the function name, and the list of argument types.…
For example, this first function is volume,…returning double, taking one double argument.…And this function is volume, returning double,…taking two double arguments.…And this one is volume, returning double,…and taking three double arguments.…And you notice that I call them with one argument,…with two arguments, with three arguments,…and, when I run this, you see we get these results.…
The cube of 2.0, the cylinder of two and two,…and the cuboid of two, three, and four.…And you'll notice that each of these has that…in their printf, so we're calling the correct functions,…
