What are other format specifiers?

In Go, Printf supports a variety of format specifiers that allow you to control how different types of data are displayed. Here are some commonly used format specifiers:

Common Format Specifiers:

1. String and Character:

   • %s - String
   • %q - Double-quoted string (with escape characters)
   • %c - Character (rune)

2. Integer:

   • %d - Decimal integer
   • %b - Binary representation
   • %o - Octal representation
   • %x - Hexadecimal representation (lowercase)
   • %X - Hexadecimal representation (uppercase)

3. Floating-Point:

   • %f - Decimal point and exponent (default)
   • %e - Scientific notation (lowercase)
   • %E - Scientific notation (uppercase)
   • %g - Uses the shortest representation between %f and %e
   • %.nf - Floating-point with n decimal places (e.g., %.2f for two decimal places)

4. Boolean:

   • %t - Boolean (true or false)

5. Pointer:

   • %p - Pointer address in hexadecimal

6. Default Format:

   • %v - Default format for the value
   • %+v - Struct with field names
   • %#v - Go-syntax representation of the value

7. Width and Precision:

   • %5d - Right-aligned integer with a width of 5
   • %-5s - Left-aligned string with a width of 5
   • %10.2f - Floating-point number with a width of 10 and 2 decimal places

Example Usage:

package main

import "fmt"

func main() {
    name := "Alice"
    age := 30
    height := 5.6
    isStudent := true

    fmt.Printf("Name: %s\n", name)
    fmt.Printf("Age: %d\n", age)
    fmt.Printf("Height: %.1f\n", height)
    fmt.Printf("Is Student: %t\n", isStudent)
}

Output:

Name: Alice
Age: 30
Height: 5.6
Is Student: true

Feel free to experiment with these format specifiers to see how they affect the output!
