Can you explain how the int type works in programming?

In the Go language, the int type represents an integer data type, the size of which depends on the processor architecture (usually 32 or 64 bits). It is used to store whole numbers without fractional parts. Variables of type int can hold both positive and negative values. For example:

var a int = 42
var b int = -7
fmt.Println(a + b) // Outputs 35

The int type is convenient for arithmetic operations and array indexing. It is important to remember that overflow behavior depends on the architecture and compiler.
