Join Dan Gookin for an in-depth discussion in this video Referencing variables with pointers, part of Learning C (2014).
- I know many see programmers who spend…their careers artfully avoiding pointers,…which is possible, but not smart.…Pointers are puzzling, yet I hope this movie…clears the air for you.…I'll explain what a pointer is, how it's used.…I promise to move nice and slow because…this topic is a very important part…of learning the C language.…The worst thing about pointers is their name.…Pointers, it's descriptive, but a poor choice…because you end up explaining a pointer…by saying a pointer points.…
That's pointless.…But I can't change the name so allow me to explain…a pointer by giving you this definition.…A pointer is a variable that holds…a memory location and address.…It's not just any address, you can't say for example,…let's see what's at memory location 96.…Pointers don't work that way.…The address must be the location…of another variable.…Pointer variables are declared similarly…to other variables, although the variable name…is prefixed by the pointer operator, the asterisk.…
You'll see an example in a moment.…The pointer variable type matches the type…
