In programming sometimes we may want to use different types of variables and variable variations, here we use Function Overloading.Graphics/Gloss/Game.hs - | - Module : Main - Copyright : Manuel M T Chakravarty - License : BSD3 - Maintainer : Manuel M T Chakravarty - Portability : haskell2011 module Graphics. Also using correct types may have some benefits to use variables (i.e memory usage, conversion required, etc.). For example, using integer variables in a function is faster than using long integer variables. C++ functions are the most flexible and effective functions for using memory and CPU operations.

In previous posts about functions, we created an addition function add() that has a and b parameters and returns sum of a and b.

By using Function Overloading, a function can be used with the same name in different parameter types and multiple variations.

Do you want to learn how to overload a function ? What is Function Overloading ? What does overloaded function means ? How we can use Function Overloading in C++ ? How we can use multiple parameter types in our functions ? Here we go,įunction Overloading is used to operate with the same function by defining it with different variable types.
