In this video, I will explain Function overloading in C++: it is a feature of the language that allows you to have more than one function with the same name in the same scope, as long as their parameter types or the number of parameters differ. This enables you to perform different operations depending on the types or the number of arguments passed to the function. The compiler differentiates these functions by their signature, which includes the function name, the number of parameters, and the types of those parameters.
When you call an overloaded function, the compiler determines the appropriate function to use based on the arguments that you pass. If there's no exact match, the compiler tries to find the best match through standard conversion rules. If the compiler can't find a match or if there's ambiguity in which function to call, it will throw an error.
