In Go language,
fmt package implements formatted I/O with functions analogous to C's printf() and scanf() function. The
fmt.Sscanln() function in Go language scans the specified string and stores the successive space-separated values into successive arguments. This function stops scanning at a newline and after the final item, there must be a newline or EOF. Moreover, this function is defined under the fmt package. Here, you need to import the "fmt" package in order to use these functions.
Syntax:
func Sscanln(str string, a ...interface{}) (n int, err error)
Parameters: This function accepts two parameters which are illustrated below:
- str string: This parameter contains the specified text which is going to be scanned.
- a ...interface{}: This parameter receives each elements of the string.
Returns: It returns the number of items successfully scanned.
Example 1:
Output:
n: 2, name: GFG, alphabet_count: 3
Example 2:
Output:
name: GFG, alphabet_count: 0
In the above example, it can be seen that the assigned value of alphabet_count was 3 still the output is 0 this is because of there is new line (\n) in between two elements "GFG" and "alphabet_count" and hence this function stop scanning at a newline.
