Can you explain what the uint type means in Go language and how it is used?

In the Go language, the uint type is an unsigned integer type, whose size depends on the platform architecture (32 or 64 bits). It can only store non-negative integers (from 0 up to a maximum value depending on the bitness).

It is used when working with integers without negative values, for example, for counters, indices, sizes, etc.

Example of usage:

var a uint = 10
var b uint = 20
sum := a + b
fmt.Println(sum) // 30

It is important to remember that operations with uint can lead to unexpected results when subtracting if the result becomes negative, because uint does not support negative values and overflow occurs.
