Example of fmt.Sscanf() function in Golang

Problem Solution:

In this program, we extract a date from a string into integer variables using fmt.Sscanf() function and print the result on the console screen.

Program/Source Code:

The source code to demonstrate the fmt.Sscanf() function is given below. The given program is compiled and executed on the ubuntu 18.04 operating system successfully.

Golang code to demonstrate the example of fmt.Sscanf() function

// Golang program to demonstrate the
// fmt.Sscanf() function

package main

import "fmt"

func main() {
	var dd int = 0
	var mm int = 0
	var yy int = 0

	var strDate string = "17-04-20"

	_, err := fmt.Sscanf(strDate, "%02d-%02d-%02d", &dd, &mm, &yy)
	if err != nil {
		panic(err)
	}

	fmt.Println("DD: ", dd)
	fmt.Println("MM: ", mm)
	fmt.Println("YY: ", yy)
}

Output:

DD:  17
MM:  4
YY:  20

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the "fmt" package then we can use a function related to the "fmt".

In the main() function, we created three integer variables dd, mm, yy that are initialized with 0. Then we extract values for dd, mm, yy variables using fmt.Sscanf() function. After that, we printed the result on the console screen.
