Function overloading is a feature in C++ that allows multiple functions with the same name but different parameter lists to exist within a class or namespace. It provides a way to create functions that perform similar operations but with different input parameters or argument types. By overloading functions, you can write more intuitive and flexible code that can handle a variety of data types or argument combinations. Let's delve into the concept of function overloading and provide examples to illustrate its usage.
Function Overloading:
Function overloading enables you to define multiple functions with the same name but different parameter lists. The compiler distinguishes between these overloaded functions based on the number, type, and order of the parameters. When a function is called, the compiler determines the appropriate overloaded function to execute based on the argument types passed in the function call.
Here's an example that demonstrates function overloading:
