100daysofcode - Day 17
Hello folks, a new day is here, let’s wrap it successfully by learning some new techniques to format a string in Golang. 
In yesterday post we talked about the string functions and how we can use them to manipulate strings in Go 
In today’s post we will learn the different ways to format a string, by moving from the boring theory part, to directly moving on directly to an interactive example to learn from it. 
Exercise
package main
import (
"fmt"
)
type point struct {
x, y int
}
func main() {
p := point{5, 7}
fmt.Printf("struct: %v\n", p)
// The %v print the struct values as they are in the
// Output: struct: {5 7}
fmt.Printf("struct: %+v\n", p)
// The %+v print the struct values with the struct field names
// Output: struct: {x:5 y:7}
fmt.Printf("struct: %#v\n", p)
// The %#v print the struct values, field names and the syntax representation
// Output: struct: main.point{x:5, y:7}
fmt.Printf("type: %T\n", p)
// The %T print the type of the variable
// Output: type: main.point
fmt.Printf("int: %d\n", 123)
// The %d print the value in base 10 representation
// Output: 123
fmt.Printf("bin: %b\n", 14)
// The %b print the value in binary
// Output: 1110
fmt.Printf("char: %c\n", 33)
// The %c print the char corresponding to the integer
// char: !
fmt.Printf("hex: %x\n", 456)
// The %x print the value in hexadecimal
// Output: 1c8
fmt.Printf("float1: %f\n", 78.9)
// The %f print the float number in it's basic form
// Output: 78.900000
fmt.Printf("float2: %e\n", 123400000.0)
fmt.Printf("float3: %E\n", 123400000.0)
// The %e and %E print the float value in different way
// Output: 1.234000e+08 or 1.234000E+08
fmt.Printf("str: %s\n", "\"string\"")
// The %s is used to print the string
// Output: "string"
fmt.Printf("str: %q\n", "\"string\"")
// The %q is used to double quote strings
// Output: "\"string\""
fmt.Printf("str: %x\n", "hex this")
// The %x render the string in base 16
// Output: 6865782074686973
fmt.Printf("pointer: %p\n", &p)
// The %p is used to print the representation of the pointer
// Output: 0x1400012a010
}
Let’s end 
this amazing post now, I hope you can learn some amazing stuff from it, and stay tuned for tomorrow’s post where we will explore new interesting topics.
