Conditionals: If

Conditionals allow your program to make decisions and execute different code based on whether certain conditions are true or false. They're essential for controlling the flow of your program.

The if Statement

The most basic conditional in Go is the if statement. It executes a block of code only when a condition is true.

age := 18

if age >= 18 {
    fmt.Println("You are an adult")
}

Notice that Go doesn't require parentheses around the condition, but the curly braces {} are required even for single-line blocks.

Comparison Operators

Go provides several operators for comparing values:

// Equal to
if x == 5 { }

// Not equal to
if x != 5 { }

// Greater than
if x > 5 { }

// Less than
if x < 5 { }

// Greater than or equal to
