GoLang - Boolean Expression

2 minute read

In this tutorial, you will learn about Boolean Expression in Go Programming with the help of example.

Boolean expressions in Go programming are used to evaluate conditions and produce a Boolean value, either true or false. These expressions are fundamental to decision-making and flow control in programming. In this tutorial, we will explore the basics of boolean expressions in Go programming, including comparison operators and logical operators, with examples in simple and easy-to-understand language. So let’s dive in and learn about boolean expressions in Go!

Comparison Operators

Comparison operators are used to compare values and evaluate the relationship between them. They return a Boolean value based on the comparison result.

Example:

package main

import "fmt"

func main() {
    var a = 5
    var b = 10

    fmt.Println("Equal to:", a == b)
    fmt.Println("Not equal to:", a != b)
    fmt.Println("Greater than:", a > b)
    fmt.Println("Less than:", a < b)
    fmt.Println("Greater than or equal to:", a >= b)
    fmt.Println("Less than or equal to:", a <= b)
}

In the example above, we compare the values of variables 'a' and 'b' using comparison operators. Each line prints the result of the respective comparison using operators like '==' (equal to), '!=' (not equal to), '>' (greater than), '<' (less than), '>=' (greater than or equal to), and '<=' (less than or equal to).

Logical Operators

Logical operators are used to combine multiple boolean expressions and evaluate their truth values. They return a boolean value based on the logical relationship between the expressions.

Example:

package main

import "fmt"

func main() {
    var x = true
    var y = false

    fmt.Println("Logical AND:", x && y)
    fmt.Println("Logical OR:", x || y)
    fmt.Println("Logical NOT:", !x)
}

In this example, we have two boolean variables, 'x' and 'y', with initial values. We use logical operators like '&&' (logical AND), '||' (logical OR), and '!' (logical NOT) to evaluate the logical relationships between the variables and print the corresponding results.

Combining Comparison and Logical Operators

Boolean expressions often involve both comparison and logical operators. By combining them, we can create more complex conditions.

Example:

package main

import "fmt"

func main() {
    var a = 5
    var b = 10
    var c = 3

    result := (a > b) && (c != 0)

    fmt.Println("Result:", result)
}

In this example, we declare three variables, 'a', 'b', and 'c', with initial values. We use comparison operators ('>', '!=') to compare the values of 'a', 'b', and 'c'. Then, using the logical AND operator '&&', we combine the comparisons to form a boolean expression stored in the variable 'result'. The final result is printed, indicating whether the condition is true or false.

Conclusion

Boolean expressions in Go programming are essential for decision-making and flow control. By using comparison operators and logical operators, you can evaluate conditions and produce Boolean results. In this tutorial, we explored comparison operators for comparing values and logical operators for combining expressions. By understanding and utilizing boolean expressions effectively, you can create dynamic and responsive programs in Go. So go ahead, practice boolean expressions, and unlock the power of decision-making in your Go programs!
