Go Boolean Expression

In Go, Boolean expressions are expressions that evaluate to either true or false. They are typically used in conditional statements and loops to control program flow based on certain conditions.

Go has a set of operators and functions that can be used to create Boolean expressions. Here are some examples:

  1. Comparison operators:
  • == (equal to)
  • != (not equal to)
  • < (less than)
  • > (greater than)
  • <= (less than or equal to)
  • >= (greater than or equal to)

These operators compare two values and return a Boolean result indicating whether the comparison is true or false.

  1. Logical operators:
  • && (logical AND)
  • || (logical OR)
  • ! (logical NOT)

These operators combine multiple Boolean expressions and return a Boolean result based on their logical relationship. For example, the && operator returns true only if both of its operands are true, while the || operator returns true if at least one of its operands is true. The ! operator negates the value of a Boolean expression, so !true is false and !false is true.

  1. Functions:
  • len() (returns the length of an array, slice, or string)
  • cap() (returns the capacity of a slice)
  • append() (appends an element to a slice)
  • make() (creates a new slice, map, or channel)

These functions can be used to create Boolean expressions by comparing their results to other values. For example, len(mySlice) > 0 is a Boolean expression that returns true if mySlice has at least one element.

Here's an example of a Boolean expression in a conditional statement:

x := 10
if x > 5 && x < 15 {
    fmt.Println("x is between 5 and 15")
}

In this example, the Boolean expression x > 5 && x < 15 is evaluated to true because x is greater than 5 and less than 15. As a result, the code inside the if statement is executed and the message "x is between 5 and 15" is printed.
