== Range of a variable ==
The range of a variable is given as the set of possible values that that variable can hold. In the case of an integer, the variable definition is restricted to whole numbers only, and the range will cover every number within its range (including the maximum and minimum). For example, the range of a [[signedness|signed]] [[16-bit]] [[Integer (computer science)|integer]] variable is all the integers from −32,768 to +32,767.
== Range of an array ==

== Range as a operator ==
[[Rust (programming language)|Rust]] have the {{Mono|..}} and {{Mono|..{{=}}}} operators.
<syntaxhighlight lang="rust">
let heartwarming = "heartwarming!".to_string();
let warm = &heartwarming[5..9];
</syntaxhighlight>
[[Zig (programming language)|Zig]] also have the {{Mono|..}} operator.
<syntaxhighlight lang="zig">
// To iterate over consecutive integers, use the range syntax.
var sum: usize = 0;
for (0..5) |i| {
sum += i;
}
