In Go language,
fmt package implements formatted I/O with functions analogous to C's printf() and scanf() function. The
fmt.Fscanln() function in Go language scans the specified text, read from r and then stores 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 Fscanln(r io.Reader, a ...interface{}) (n int, err error)
Parameters: This function accepts two parameters which are illustrated below:
- r io.Reader: This parameter contains the scanned specified texts.
- a ...interface{}: These parameters are accepting each specified elements.
Returns: It returns the number of items successfully scanned.
Example 1:
Output:
2: gfg, 9
Example 2:
Output:
4: gfg, 9, true, 5.78
