A declaration begins with the type, followed by the name of one or more variables. For example,
int high, low, results;
Declarations can be spread out, allowing space for an explanatory comment. Variables can also be initialised when they are declared, this is done by adding an equals sign and the required value after the declaration.
int high = 250; /* Maximum Temperature */ int low = -40; /* Minimum Temperature */ int results; /* Series of temperature readings */
