Join Dan Gookin for an in-depth discussion in this video Adding a function, part of Up and Running with C.
- The C library is brimming with functions.…These functions do a lot of things, but perhaps…not everything you need for your programs.…Therefore, when necessary, you can…concoct your own C language functions.…In fact, most programs have dozens,…if not hundreds, of their own functions.…In this movie, I introduce you to the function.…You'll see how to set up and prototype a function,…how to call or access the function,…and how to bail out of a function early.…Like everything in the C language, a function…has a certain style, and various etiquettes must…be followed to add a function to your code.…
A function has a type, a name and arguments in parentheses.…The type is a value returned by the function, its output.…The name is a unique name that identifies the function.…The arguments are zero, one or more values…passed to the function, its input.…Here, the alpha function has no input…or output, which is valid in the C language.…Therefore, it's a void function.…Void is a variable type, which means…I have no variable type.…
