Glad you asked, this is pretty easy in Haskell. Here’s my solution you should easily be able to expand on.

-- This is a nice problem that we can write a very easy 
-- piece of Haskell code for to demonstrate its simplicity! 
 
-- First, we need Peano numbers so that we can count things. 
-- Always define your own, never trust the built-in integers! 
 
data Nat = Zero | Succ Nat 
  deriving (Eq, Show) 
 
-- Now I will set the ground work for the rest of our program. 
-- This is a pretty obvious and self-explanatory data type.  
-- We will use it to create a stream of functors that ends in a Pure constructor.

I like the other solutions, but they all require an operating system which is a bit of pain to install for something as simple as this.

I suggest:
section .text
global boot
bits 16
global sectors_to_load

boot:
xor bp, bp
mov ds, bp
mov ss, bp
mov bp, 0x7000
mov sp, bp ; better set up a stack for the function call
mov bx, smile ; load the address of our string
call bios_print_string
call bios_print_string
call bios_print_string
mov bx, new_line
call bios_print_string
call bios_print_string
mov bx, new_line
call bios_print

Normally I don’t give answers to homework questions outright, but with such a tricky question as this, the least I can do is give you some pointers (preferably void*s) in the right direction. This exercise requires an extensive knowledge of x86 assembly and function pointers to solve correctly. As requested, there is a function that prints “Smile!” (no newline), which is called in such a way that the program’s output is:

Smile!Smile!Smile!

Smile!Smile!

Smile!

Extending this to work for additional lines is an exercise left to the reader.

#include<stdio.h> 
#define while printf

In JavaEE:
* Make a maven war project and add Hibernate, JaxB, deltaspike-data-JPA and RESTEasy as dependencies

* Make a simple entity "Message" containing a String atribute and "MessageList" One
* Annotate each class with @Entity @XmlRootElement
* Add an jaxb.index file on these classes package listing these two Entities
* Annotate your Attribute by @XmlElement @NotNull @Size(min=2, max=10)
* Make a MessageListDao interface annotted with DS @Repository @Path("/")
* Make a simple persistence.xml file mapping to your database

* Make an interface and a REST "MessageRESTService"
* Add a method to t

This outputs the smiles you requested

I'll have a go, although I can bet that your teacher doesn't expect to see a SQL solution..

just replace the "TOP 3" with your desired count :)

CREATE FUNCTION dbo.NOT_MY_HOMEWORK(@HOW_MANY INT)

    WHILE (@COUNT < @HOW_MANY) 
    BEGIN 
        SET @COUNT = @COUNT + 1 
        SET @FROWNEDUPON = @FROWNEDUPON + 'Smile!' 
    END 
     
    RETURN @FROWNEDUPON

Kim Moser suggested:

Just write a program that outputs random sequences of letters and punctuation. If you let it run long enough, eventually it will output the desired sequence.

That sounds like a plan.

The C# System.Random.next() method will return a random number between 0 and 2,147,483,6467 (which is 2 to the power 31, minus one). The unicode value for the S is 83, so all we need to do is pick random numbers between 0 and 2.1 billion until 83 pops up, then move onto m…

It takes a few guesses to find the correct numbers, on testing between 77 billion and 107 billion numbers picked and discarded

All the solutions I’ve seen so far are unsatisfactory in that they take no advantage of the advances in the hottest field in Computer Science: Machine Learning. But this is your lucky day, and courtesy of Google’s release of the TensorFlow Open Source Library for Machine Intelligence, I am able to remedy this problem, but providing a truly intelligent (artificially!) solution:

#!/usr/bin/env python3 
 
import tensorflow as tf 
 
sess = tf.InteractiveSession() 
n = 3 
 
# input will be a matrix containing elements 1 ... n^2 
inp = tf.reshape(tf.linspace(1.0, n*n, n*n), [n, n]) 
# Generate a matrix with rows 1..n 
r 

EDIT: Indicate the function to print 'Smile!'

In the Bourne Shell (ash or bash). The print function is 's' or 'd0 that'. With recursion:

#! /bin/sh 
e(){ echo -n $1 ;};s(){ e S; e m;e i;e l;e e;e '!';}; 
cd(){ if [ -n "$1" ];then shift;s;cd "$@" ; else echo "";fi;} 
d0(){ if [ -n "$1" ];then cd "$@";shift;d0 "$@";fi;} 
 
d0 your own homework 

And in ANSI C (with recursion and abuse of the C pre-processor), same algorithm. The print function is 'e(S)' or 'do({"that", 0})'

#include <unistd.h> 
#define T C Z 
#define X Z V 
#define R char 
#define V void 
#define C const 
#define U return 
#define Z static 
#define do d 
T R S[] 

Not sure if any solution in Whitespace has been posted. Anyway, here you have my go at this problem:

Guaranteed to work with the Ruby interpreter from here. I’m not sure how strict the standard is implemented across interpreters and I didn’t check any other but the Ruby one.

For those still keen to understanding what’s inside, here’s the pseudocode outline (please ignore the row labels; they only ma

Got it, use the function as often as needed. What about a C++ version, I did full unit test and coverage test, also make it ran for 2000 times to prove the correctness from 1 line to 2000 lines. No error till now, it is very robust. Also, it crosses platforms, you can compile and run it on Unix/Linux, Windows, or MacOS. Your professor will be satisfied. Absolutely! And you are welcome!

#include <iostream> 
 
void SomeoneElseWriteFunctionForMe(int depth) 
{ 
    if (depth > 0) 
    { 
        if (depth % 2 == 1) 
        { 
            SomeoneElseWriteFunctionForMe(-depth); 
        } 
        else

Almost everybody seems to assume that the teatcher wants the smiles per lines to "count down" from three per line... but the wording "have the program use the function as often as needed" could indicate that the solution should scale.

So I have assumed that the goal is to end up with one line with one "smile!", preceded by longer lines, each one smile shorter than the previous line. Except the very first line, which may not be quite long enough, depending on the total number of smiles. Anyway, I really think that is what the teacher really wants in his heart of hearts!

Like the only other correct answer on the page mentions, the behaviour is undefined. Which means a compiler can do exactly as it pleases when asked to convert this statement. It can convert in such a way that you get 5 or 6 or 99 or it could create code to wipe off your entire hard drive. It would still be a

Here is the solution in the most glorious of all programming languages, TrumpScript:

make democrats 1000000 
make republicans 1000001 
make America 1000003 
make terrorists "Smile!" 
make government ,republicans - democrats; 
make world ,America - democrats; 
make president ,America - America; 
make Trump president 
as long as ,Trump < world;: 
    make Trump president 
    tell ,world about * terrorists; 
    make world ,world - government; 
    Trump should be our only leader! 
America is great. 

Though you must use functions, you actually don’t need them, you don’t need functions in TrumpScript. This is the best answer
