struct name {
  variable list
  .
  .
};

When a structure is defined, the struct keyword is used followed by the name of the structure. The variable list is then defined between the curly brackets.

Let's take a look at how we can create and use a structure by changing the previous sketch, which used the analogRead() function to read the TMP36 temperature, to use a structure. The first thing we need to do is to define a structure that will store ...
