Step by Step solution about How to resolve the algorithm Loops/Break step by step in the Go programming language

This Go program demonstrates the use of rand.Intn to generate random integers and a loop with a break statement to exit the loop when a specific condition is met.

• Importing Libraries: The program imports three libraries:

  • "fmt" for input and output operations (e.g., printing to the console).
  • "math/rand" for generating random numbers.
  • "time" for obtaining the current time (used for initializing the random number generator).

• Main Function: The program's entry point is the main function.

• Seeding the Random Number Generator: rand.Seed(time.Now().UnixNano()) initializes the random number generator using the current time as a seed. This ensures that the generated random numbers are not always the same.

• Infinite Loop: The program enters an infinite loop using for {}.

• Generating Random Integers: Inside the loop, rand.Intn(20) generates a random integer between 0 and 19 (inclusive) and assigns it to variable a. The Intn function generates a non-negative random integer less than the provided number.

• Printing Random Integer: The program prints the generated integer a to the console.

• Checking for Break Condition: After generating and printing the first random integer, the program checks if a is equal to 10. If a is 10, the break statement is executed, which exits the infinite loop.

• Generating and Printing Second Random Integer: If a is not equal to 10, the program generates a second random integer b using rand.Intn(20) and prints it to the console.

• Loop Continues: The loop continues back to the beginning, generating random integers a and b until a becomes equal to 10, at which point the loop exits.

package main

import "fmt"
import "math/rand"
import "time"

func main() {
    rand.Seed(time.Now().UnixNano())
    for {
        a := rand.Intn(20)
        fmt.Println(a)
        if a == 10 {
            break
        }
        b := rand.Intn(20)
        fmt.Println(b)
    }
}
