Go language provides inbuilt support for generating random numbers of the specified type with the help of a math/rand package. This package implements pseudo-random number generators. These random numbers are generated by a source and this source produces a deterministic sequence of values every time when the program run. And if you want to random numbers for security-sensitive work, then use the crypto/rand package.

You are allowed to generate a pseudo-random number of a 32-bit integer as an uint32 type from the default source with the help of the Uint32() function provided by the math/rand package. So, you need to add a math/rand package in your program with the help of the import keyword to access the Uint32() function.

Syntax:

func Uint32() uint32

Let us discuss this concept with the help of the given examples:

Example 1:




// Golang program to illustrate
// how to get a random number
package main
  
import (
    "fmt"
    "math/rand"
)
  
// Main function
func main() {
  
    // Finding random numbers
    // Using Uint32() function
    res_1 := rand.Uint32()
    res_2 := rand.Uint32()
    res_3 := rand.Uint32()
  
    // Displaying the result
    fmt.Println("Random Number 1: ", res_1)
    fmt.Println("Random Number 2: ", res_2)
    fmt.Println("Random Number 3: ", res_3)
}


Output:

Random Number 1:  2596996162
Random Number 2:  4039455774
Random Number 3:  2854263694

Example 2:




// Golang program to illustrate the
// use of the random numbers
package main
  
import (
    "fmt"
    "math/rand"
)
  
// Function
func uint32random(value_1, value_2 uint32) uint32 {
    return value_1 + value_2 + rand.Uint32()
  
}
  
// Main function
func main() {
  
    // Getting result from uint32random() function
    res1 := uint32random(10, 3)
    res2 := uint32random(44, 59)
    res3 := uint32random(130, 50)
  
    // Displaying results
    fmt.Println("Result 1: ", res1)
    fmt.Println("Result 2: ", res2)
    fmt.Println("Result 3: ", res3)
}


Output:

Result 1:  2596996175
Result 2:  4039455877
Result 3:  2854263874
