A function is a collection of variables, expressions, and control flow statements (loops and branches). In fact, any of the code you have learned about in the course so far can be used in a function. Explore C++ functions in this video.
- [Instructor] In the previous video we looked at…class enumerations, in this video we're going to…take a look at function return types, function names,…function parameters, the function body…and organizing functions.…Let's begin by understanding what exactly are C++ functions.…A function is a collection of variables, expressions…and control flow statements, loops and branches.…In fact, any of the code we have learned so far,…can be used in a function.…The first part of a function that we write…is called the signature.…
Here's an example of function signature.…If you add an opening and closing pair of curly braces,…with some code that the function actually performs,…then we have a complete function, a definition.…We could then use our new function…in another part of our code, like this.…When we use a function, we say that we call it.…At the point where we call bombPlayer,…our program's execution branches to the code contain…within that function, the function will run until…it reaches the end or is told to return.…
