Integer is an Abstract Data Type used in programming languages.
In many languages, integer types have a fixed size, such as 8, 16, 32, or 64 bits. This determines the range of values the integer can store.
Some integer types are platform dependent. In Go, int and uint are either 32-bit or 64-bit depending on the target architecture.
For example:
package main
import (
"fmt"
"strconv"
)
func main() {
fmt.Println(strconv.IntSize)
}On a 64-bit Go target this prints 64; on a 32-bit Go target this prints 32. Because of this, Go code that needs an exact integer width should use types like int32, int64, uint32, or uint64.

Q: What does strconv.IntSize tell you in Go?
A: It tells you whether int is 32-bit or 64-bit for the current Go target.
