# Random Numbers

This Go code demonstrates the use of the `rand` package to generate random numbers. Let's go through the code with inline comments and explanations:

```go
// Importing necessary packages.
import (
	"fmt"
	"math/rand"
	"time"
)

// The main function, where the execution of the program begins.
func main() {
	// Generating random integers between 0 and 99.
	fmt.Print(rand.Intn(100), ",")
	fmt.Print(rand.Intn(100))
	fmt.Println()

	// Generating a random floating-point number between 0.0 and 1.0.
	fmt.Println(rand.Float64())

	// Generating random floating-point numbers in a specific range.
	fmt.Print((rand.Float64()*5)+5, ",")
	fmt.Print((rand.Float64()*5)+5)
	fmt.Println()

	// Using a specific seed to generate random numbers (seeded by current time).
	s1 := rand.NewSource(time.Now().UnixNano())
	r1 := rand.New(s1)
	fmt.Print(r1.Intn(100), ",")
	fmt.Print(r1.Intn(100))
	fmt.Println()

	// Using a specific seed (42) to generate random numbers.
	s2 := rand.NewSource(42)
	r2 := rand.New(s2)
	fmt.Print(r2.Intn(100), ",")
	fmt.Print(r2.Intn(100))
	fmt.Println()

	// Using the same seed (42) to generate consistent random numbers.
	s3 := rand.NewSource(42)
	r3 := rand.New(s3)
	fmt.Print(r3.Intn(100), ",")
	fmt.Print(r3.Intn(100))
}
```

#### Output

```

Explanation:

1. **Generating Random Integers:**
   * `rand.Intn(100)` generates a random integer between 0 and 99.
2. **Generating Random Floating-Point Numbers:**
   * `rand.Float64()` generates a random floating-point number between 0.0 and 1.0.
   * `(rand.Float64()*5)+5` generates a random floating-point number in the range \[5.0, 10.0).
3. **Seeding Random Number Generator:**
   * `rand.NewSource(time.Now().UnixNano())` creates a new source using the current Unix timestamp as the seed.
   * `rand.New(s1)` creates a new random number generator using the source.
4. **Consistent Random Numbers with the Same Seed:**
   * Using a specific seed (42) results in the same sequence of random numbers each time.

This code demonstrates the basic usage of the `rand` package in Go to generate random numbers, both integers and floating-point, with and without seeding. Seeding is useful to ensure reproducibility if needed.
