What is the difference between uint and int types?

The main difference between uint and int in Golang is as follows:

• int: This is a signed integer type. It can represent both positive and negative numbers, including zero. Its size is determined by the system architecture (32 or 64 bits).
• uint: This is an unsigned integer type. It can only represent non-negative numbers (zero and positive). Its size is also determined by the system architecture.

// Example of using int
var a int = -10 // Can store negative values
var b int = 5

// Example of using uint
var c uint = 10 // Can only store non-negative values
// var d uint = -5 // Will cause a compile-time error

In short: int is signed (positive, negative, zero), uint is unsigned (positive, zero). The choice between them depends on whether you need to store negative values. uint is often used for counters, sizes, indices, and other quantities that by their nature cannot be negative.
