Recap - Making Comparisons

Part of the Fundamentals section of Coddy's GO journey — lesson 28 of 109.

Challenge

Easy

Complete the code to evaluate different comparison and logical expressions and print the results.

Try it yourself

package main

import "fmt"

func main() {
  // Given variables
  age := 25
  score := 85
  isPremium := true
  
  // TODO: Create a boolean variable named 'isAdult' that checks if age is greater than or equal to 18
  
  // TODO: Create a boolean variable named 'isPassing' that checks if score is greater than or equal to 70
  
  // TODO: Create a boolean variable named 'isEligible' that checks if the person is both an adult AND has premium status
  
  // TODO: Create a boolean variable named 'needsImprovement' that checks if the score is less than 70 OR age is less than 20
  
  // TODO: Create a boolean variable named 'isRejected' that is the NEGATION (opposite) of isPassing
  
  // Print results
  fmt.Println("Is Adult:", isAdult)
  fmt.Println("Is Passing:", isPassing)
  fmt.Println("Is Eligible:", isEligible)
  fmt.Println("Needs Improvement:", needsImprovement)
  fmt.Println("Is Rejected:", isRejected)
}
