Variables contain data, and data can be of different *data types*, or *types* for short. Golang is a **statically typed language**; this means the compiler must know the types of all the variables, either because they were explicitly indicated or because the compiler can infer the type from the code context. A **type** defines the set of values and the set of operations that can take place on those values. 

**Type `uint64`** in Golang is the set of all unsigned 64-bit integers. The set ranges from 0 to  18446744073709551615. Below is how you declare a variable of type `uint64`:
```Go
var var_name uint64
```
# Example



package main
import "fmt"
 
func main() {
     
  var var1 uint64 = 1000000000
  fmt.Printf("Type of var1: %T", var1)
}

# Explanation
The above code declares the variable `var1` with type `uint64`, and displays its type using the `Printf` method from the `fmt` package. 


What is type uint64 in Golang?

Type uint64 in Golang represents unsigned 64-bit integers ranging from 0 to 18446744073709551615.
