Input

[Kreel]

Sorry for the silly question.i'm a complete newbie.
what is the best way to capture a char from standard input
(keyboard) ? And an integer?
thx in advance.

Read from os.Stdin. For example:

package main

import (
"fmt";
"os"
)

func main () {
bytes := make ([]byte, 20);

os.Stdin.Read (bytes);

fmt.Print (string (bytes))
}

package main

import (
"fmt";
"os";
"bufio";
)

func main () {

in := bufio.NewReader(os.Stdin);
//the string value of the input is stored in the variable input
input, err := in.ReadString('\n');
fmt.Println(input); //output the string
if err != nil {
// handle error
}

//in case you need to convert it to integer value. import strconv and
use strconv.Atoi(variable)
}

Hope it is useful

Alternatively, if you want to read  integers from the standard input, files, etc, you can use the scanner package:

http://code.google.com/p/golang/source/browse/src/pkg/scanner

You can do something like

sc := scanner.NewScanner(os.Stdin)
n := sc.NextInt()
fmt.Print(n)
