package main

import (
    "fmt"
    "math/rand"
    "time"
)

func main() {
    // Seed the random number generator with current time
    rand.Seed(time.Now().UnixNano())

    // Generate a random number between 0 and 100
    randomNum := rand.Intn(101)

    // Print the generated random number
    fmt.Println("Random number:", randomNum)
}

Explanation:

1. package main: Defines that this Go file is part of the main package.

2. import: Imports necessary packages. fmt is used for formatting and printing, math/rand for generating random numbers, and time to work with time-related functions.

3. func main() { ... }: Defines the entry point of the program, where the execution starts.

4. rand.Seed(time.Now().UnixNano()): Seeds the random number generator using the current time. It ensures that the sequence of random numbers generated is different each time the program is run.

5. randomNum := rand.Intn(101): Generates a random integer number between 0 and 100 (inclusive) using rand.Intn(). The argument specifies the upper bound (exclusive).

6. fmt.Println("Random number:", randomNum): Prints the generated random number to the console along with a descriptive message.
