Define a string containing variables and expressions

Given variables a=3 and b=4 output "3+4=7"

clojure

(format "%d + %d = %d" a b (+ a b))

cpp C++/CLI .NET 2.0

Console::WriteLine(L"{0}+{1}={2}", a, b, a+b);

cpp

std::printf("%d+%d=%d\n", a, b, a+b);

cpp

std::cout << boost::format("%|1|+%|1|=%|1|") % a % b % (a+b) << std::endl;

csharp

int a = 3;
int b = 4;
Console.WriteLine("{0}+{1}={2}", a,b,a+b);

erlang

A = 3, B = 4,
io:format("~B+~B=~B~n", [A, B, (A+B)]).

fantom

echo("$a+$b=${a+b}")

fsharp

let a, b = 3, 4
let mystr = sprintf "%d+%d=%d" a b (a+b)
printfn "%s" mystr

a, b := 3, 4
fmt.Printf("%d+%d=%d\n", a, b, a + b)

a, b := 3, 4
fmt.Println(a, "+", b, "=", a+b)

groovy

println "$a+$b=${a+b}"

groovy

printf "%d+%d=%d\n", a, b, a + b

haskell

import Text.Printf

main = do
let a = 3
let b = 4
printf "%d+%d=%d" a b (a + b)

haskell

a = 3
b = 4
s = show a ++ "+" ++ show b ++ "=" ++ show (a + b)
main = putStrLn s

java

System.out.println(a + "+" + b + "=" + (a+b));

java 1.5 or later

System.out.printf("%d+%d=%d\n", a, b, a + b);

ocaml

Printf.printf "%d+%d=%d" a b (a+b);;

ocaml

Printf.printf "%d+%d=%d" a b (a+b);;

perl

print "$a+$b=${\($a+$b)}\n";

perl

sprintf("%d+%d=%d", $a, $b, $a + $b);

perl

print $a, '+', $b, '=', $a + $b;

php

echo "$a+$b=".($a+$b);

php

printf("%d+%d=%d\n", $a, $b, $a + $b);

python

class EvalDict(dict):
def __getitem__(s, k):
return eval(k, s)

a=3; b=4
"%(a)d+%(b)d=%(a+b)d" % EvalDict(locals())

python

a=3; b=4
"%d+%d=%d" % (a, b, a+b)

ruby

puts "#{a}+#{b}=#{a+b}"

ruby

puts "#{a}+#{b}=%s" % (a + b)

scala Java 1.5 or later

printf("%d+%d=%d\n", a, b, a + b)

scala

"%d+%d=%d".format(a, b, a + b)

scala 2.10

s"$a + $b = ${a+b}"
