True and False
True and false logic is represented using the Boolean type, bool. Use this type when you need an on/off switch in your code. The value of a bool can only ever be true or false. The zero value of a bool is false.
When using a comparison operator such as == or >, the result of that comparison is a bool value.
In this code example, we use comparison operators on two numbers. You'll see that the result is a bool:
package main
import "fmt"
func main() {
fmt.Println(10 > 5)
fmt.Println(10 == 5)
}
Running the preceding code shows the following output:
true false
Exercise 3.01: Program to Measure Password Complexity
An online portal creates user accounts for its users and accepts passwords that are only 8-15 characters long. In this exercise, we write a program for the portal to display whether the password entered meets the character requirements. The character requirements are as follows:
- Have a lowercase...
