Go Output

Description

Go has different functions to output text, primarily in the `fmt` package. `Print`, `Println`, and `Printf` are the most common.

Pros & Cons

✅ Pros

Formatting: `Printf` offers powerful C-style formatting.

❌ Cons

None.

When to Use

Debugging and displaying information to standard output.

Example

Difference between Println and Printf.

package main
import "fmt"

func main() {
    name := "John"
    age := 30
    
    fmt.Println("Hello World!")           // Adds newline
    fmt.Print("No newline here. ")
    fmt.Printf("Name: %s, Age: %d\n", name, age) // Formatted
}

Best Practices

Use `%v` in `Printf` to print the default format of any value.
