In this task, the goal is to input a string and the integer 75000, from the normal user interface.

Text Terminal

ALGOL 68

print("Enter a string: ");
STRING s := read string;
print("Enter a number: ");
INT i := read int;
~

This demo shows a same-line prompt, and that the integer i becomes 0 if the line did not parse as an integer. <lang awk> ~/src/opt/run $ awk 'BEGIN{printf "enter a string: "}{s=$0;i=$0+0;print "ok,"s"/"i}' enter a string: hello world ok,hello world/0 75000 ok,75000/75000 </lang>

BASIC

Works with: QuickBasic version 4.5

 INPUT "Enter a string: ", s$
 INPUT "Enter a number: ", i%

Works with: FreeBASIC

 dim s as string
 dim i as integer
 
 input "Enter a string: ", s
 input "Enter the integer 75000: ", i

Befunge

This prompts for a string and pushes it to the stack a character at a time (~) until end of input (-1).

<>:v:"Enter a string: "
 ^,_ >~:1+v
     ^    _@

Numeric input is easier, using the & command.

<>:v:"Enter a number: "
 ^,_ & @

C

Works with: gcc

<lang c> #include <stdio.h>

int main(int argc, char* argv[])
{
        int input;
        if((scanf("%d", &input))==1)
        {
                printf("Read in %d\n", input);
                return 1;
        }
        return 0;
}</lang>

C++

Works with: g++

<lang cpp> #include <iostream>

#include <istream>
#include <ostream>
#include <string>
using namespace std;

int main()
{
     // while probably all current implementations have int wide enough for 75000, the C++ standard
     // only guarantees this for long int.
     long int integer_input;
     string string_input;
     cout << "Enter an integer:  ";
     cin >> integer_input;
     cout << "Enter a string:  ";
     cin >> string_input;
     return 0;
}</lang>

Note: The program as written above only reads the string up to the first whitespace character. To get a complete line into the string, replace <lang cpp> cin >> string_input;</lang> with <lang cpp> readline(cin, string_input);</lang>

C#

<lang csharp> using System;

 namespace C_Sharp_Console {
 
     class example {
 
         static void Main() {
             string word;
             int num;
             
             Console.Write("Enter an integer: ");
             num = Console.Read();
             Console.Write("Enter a String: ");
             word = Console.ReadLine();
         }
     }
 }</lang>

Clojure

<lang clojure>(import '(java.util Scanner)) (def scan (Scanner. *in*)) (def s (.nextLine scan)) (def n (.nextInt scan)) </lang>

Common Lisp

<lang lisp>(format t "Enter some text: ") (let ((s (read-line)))

   (format t "You entered ~s~%" s))

(format t "Enter a number: ") (let ((n (read)))

   (if (numberp n)
       (format t "You entered ~d.~%" n)
     (format t "That was not a number.")))</lang>

D

<lang D>import tango.io.Console; import Integer = tango.text.convert.Integer;

void main() {

 int num;
 char[] word;
 Cout("Enter an integer:")();
 num = Integer.parse(Cin.get());
 Cout("Enter a string:")();
 word = Cin.get();
}</lang>

Erlang

<lang erlang> {ok, [String]} = io:fread("Enter a string: ","~s").

{ok, [Number]} = io:fread("Enter a number: ","~d").</lang>

Alternatively, you could use io:get_line to get a string: <lang erlang> String = io:get_line("Enter a string: ").</lang>

FALSE

FALSE has neither a string type nor numeric input. Shown instead are routines to parse and echo a word and to parse and interpret a number using the character input command (^).

[[^$' =~][,]#,]w:
[0[^'0-$$9>0@>|~][\10*+]#%]d:
w;! d;!.

Forth

Input a string

<lang forth> : INPUT$ ( n -- addr n )

   PAD SWAP ACCEPT
   PAD SWAP ;</lang>

Input a number

The only ANS standard number interpretation word is >NUMBER ( ud str len -- ud str len ), which is meant to be the base factor for more convenient (but non-standard) parsing words. <lang forth> : INPUT# ( -- u true | false )

  0. 16 INPUT$ DUP >R
  >NUMBER NIP NIP 
  R> <> DUP 0= IF NIP THEN ;</lang>

Works with: GNU Forth

<lang forth> : INPUT# ( -- n true | d 1 | false )

   16 INPUT$ SNUMBER? ;</lang>

Works with: Win32Forth

<lang forth> : INPUT# ( -- n true | false )

   16 INPUT$ NUMBER? NIP
   DUP 0= IF NIP THEN ;</lang>

Note that NUMBER? always leaves a double result on the stack. INPUT# returns a single precision number. If you desire a double precision result, remove the NIP.

Here is an example that puts it all together:

<lang forth> : TEST

  ." Enter your name: " 80 INPUT$ CR
  ." Hello there, " TYPE CR
  ." Enter a number: " INPUT# CR
  IF   ." Your number is " .
  ELSE ." That's not a number!" THEN CR ;</lang>

Fortran

Works with: Fortran version 90 and later

<lang fortran> character(20) :: s integer :: i

print*, "Enter a string (max 20 characters)" read*, s print*, "Enter the integer 75000" read*, i </lang>

Groovy

<lang groovy> word = System.in.readLine()

num = System.in.readLine().toInteger()</lang>

Haskell

<lang haskell> main = do

    putStr "Enter a string: "
    str <- getLine
    putStr "Enter an integer: "
    num <- readLn :: IO Int 
    putStrLn $ str ++ (show num)</lang>

Note: :: IO Int is only there to disambiguate what type we wanted from read. If num were used in a numerical context, its type would have been inferred by the interpreter/compiler.

Java

<lang java> import java.io.BufferedReader;

import java.io.InputStreamReader;

public class GetInput {
    public static void main(String[] args) throws Exception {
        BufferedReader sysin = new BufferedReader(new InputStreamReader(System.in));
        int number = Integer.parseInt(sysin.readLine());
        String string = sysin.readLine();
    }
}</lang>

Works with: Java version 1.5/5.0+

<lang java> import java.util.Scanner;

Scanner stdin = new Scanner(System.in);
String string = stdin.nextLine();
int number = stdin.nextInt();</lang>

Logo

Logo literals may be read from a line of input from stdin as either a list or a single word. <lang logo> make "input readlist ; in: string 75000

show map "number? :input  ; [false true]

make "input readword   ; in: 75000
show :input + 123       ; 75123 
make "input readword   ; in: string 75000
show :input             ; string 75000</lang>

Metafont

<lang metafont>string s; message "write a string: "; s := readstring; message s; message "write a number now: "; b := scantokens readstring; if b = 750:

 message "You've got it!"

else:

 message "Sorry..."

fi; end</lang>

If we do not provide a number in the second input, Metafont will complain. (The number 75000 was reduced to 750 since Metafont biggest number is near 4096).

PostScript

Works with: PostScript version level-2

<lang postscript> %open stdin for reading (and name the channel "kbd"):

/kbd (%stdin) (r) file def
%make ten-char buffer to read string into:
/buf (..........) def
%read string into buffer:
kbd buf readline</lang>

At this point there will be two items on the stack: a boolean which is "true" if the read was successful and the string that was read from the kbd (input terminates on a <return>). If the length of the string exceeds the buffer length, an error condition occurs (rangecheck). For the second part, the above could be followed by this:

<lang postscript> %if the read was successful, convert the string to integer:

{cvi} if</lang>

which will read the conversion operator 'cvi' (convert to integer) and the boolean and execute the former if the latter is true.

PowerShell

<lang powershell> $string = Read-Host "Input a string"

$number = Read-Host "Input a number"</lang>

Python

Input a string

<lang python> string = raw_input("Input a string: ")</lang> In Python 3.0, raw_input will be renamed to input(). The Python 3.0 equivalent would be <lang python> string = input("Input a string: ")</lang>

Input a number

While input() gets a string in Python 3.0, in 2.x it is the equivalent of eval(raw_input(...)). Because this runs arbitrary code, and just isn't nice, it is being removed in Python 3.0. raw_input() is being changed to input() because there will be no other kind of input function in Python 3.0. <lang python> number = input("Input a number: ") # Deprecated, please don't use.</lang> Python 3.0 equivalent: <lang python> number = eval(input("Input a number: ")) # Evil, please don't use.</lang> The preferred way of getting numbers from the user is to take the input as a string, and pass it to any one of the numeric types to create an instance of the appropriate number. <lang python> number = float(raw_input("Input a number: "))</lang> Python 3.0 equivalent: <lang python> number = float(input("Input a number: "))</lang> float may be replaced by any numeric type, such as int, complex, or decimal.Decimal. Each one varies in expected input.

puts "Integer = " + i.to_s</lang>

Scheme

The read procedure is R5RS standard, inputs a scheme representation so, in order to read a string, one must enter "hello world" <lang scheme> (define str (read))

 (define num (read))
 (display "String = ") (display str)
 (display "Integer = ") (display num)</lang>

] do. </lang>

Standard ML

<lang sml>print "Enter a string: "; let val str = valOf (TextIO.inputLine TextIO.stdIn) in (* note: this keeps the trailing newline *)

 print "Enter an integer: ";
 let val num = valOf (TextIO.scanStream (Int.scan StringCvt.DEC) TextIO.stdIn) in
   print (str ^ Int.toString num ^ "\n")
 end

end</lang>

Tcl

Like LISP, there is no concept of a "number" in TCL - the only real variable type is a string (whether a string might represent a number is a matter of interpretation of the string in a mathematical expression at some later time). Thus the input is the same for both tasks:

<lang tcl> set str [gets stdin]

 set num [gets stdin]</lang>

possibly followed by something like

<lang tcl> if {![string is integer $num]} then { ...do something here...}</lang>

If the requirement is to prompt until the user enters the integer 75000, then:

<lang tcl>set input 0 while {$input != 75000} {

   puts -nonewline "enter the number '75000': "
   flush stdout
   set input [gets stdin]

}</lang> or <lang tcl>proc question {var message} {

   upvar 1 $var v
   puts -nonewline "$message: "
   flush stdout
   gets stdin $v

} question name "What is your name" question task "What is your quest" question doom "What is the air-speed velocity of an unladen swallow"</lang>
