Understanding Invoking Functions and Methods in Programming

In the context of functions, "invoking" means calling a function and passing in arguments.

For example, if you have a function called `myFunction` that takes two arguments, `a` and `b`, you can invoke it by calling it like this:
```
myFunction(a, b)
```
When you call a function, you are invoking it with the arguments you want to pass in. The function will then execute and perform the actions defined within it based on those arguments.

In the context of object-oriented programming, "invoking" can also refer to calling a method on an object. For example, if you have an object called `myObject` that has a method called `doSomething`, you can invoke that method by calling it like this:
```
myObject.doSomething()
```
When you call a method on an object, you are invoking that method and passing in any necessary arguments. The method will then execute and perform the actions defined within it based on those arguments.
