Sorry I wasn't aware of the rules before.

Updated
Now 14 lines with C# to make it compile and run online, you can try it online at: http://london.gs.aster.arvixe.com/default.aspx
Question: How many lines will yours take on the server side that will allow us to try it online?

using System;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class _Default : System.Web.UI.Page
{protected void Page_Load(object sender, EventArgs e){}
protected void Button1_Click(object sender, EventArgs e)
{ string sentence = TextBox1.Text;
var sentenceQuery = from sentenceIn in sentence.ToLower().ToCharArray()
group sentenceIn by sentenceIn into m
select new { Key = m.Key, Count = m.Count() };
foreach (var item in sentenceQuery)
{Label1.Text += string.Format("Character: {0} Appears {1} time/s <br />", item.Key.ToString(), item.Count);}}}

omo_to_dun:
Your code cannot compile as is! Javanian's code can be compiled and run. Mine can simply be pasted onto a Python CLI and it will run. You have used ojoro. And btw, it only runs for that particular string.

Ok so here is my own...done in python and took 7 lines.

@javania i Also tried it in java , took 7 lines too....same approach i used in python

Nice one. I like the way you replaced the '0' with 'No' inside the output parameter.

Thnx mate..... Figured its shorter that way

omo_to_dun: @OP, so it looks like I'm the winner (with four lines).

a, s = [0] * 128, "The quick brown Fox jumps over the lazy Dog".lower()
for c in s: a[ord(c)] = a[ord(c)] + 1

for i in range(97,123): print("{0} {1}'s".format('No' if a[i] == 0 else a[i], chr(i)))

Wow.... magnificent...tho u used 3 lines .... But its nt yet over.

Lol...thnx mate....your method used less characters tho so I'd giv it to you...bravo

What is the point of optimizing down to X lines if the approach works correctly and doesn't have any major unnecessary steps?

The fewer the lines d more complex d algorithm because u hav to achieve as much as possible with each line. And dat is actually what the challenge was

not necessarily true... I think you are confusing "syntax" for "algorithm"... That I used
while(i < 8 )
{//code}
or used
for(i = 0; i < 8 ; )
{//code}

does not change the fact that I used a loop in my program or algorithm and probably does not speed up or slow down the program in any way

and this is a biased challenge... I can never write a code that short in C++.... 6 lines... Mostly

True but I also stated earlier that it tests both the algorithm and how easy or complex it is to achieve d same result with various languages and their syntax

And for the c++ etc issue I count only the lines in the main methods

@omo_to_dun
In that case the code I posted before has only 6 lines and anyone can try it online at http://london.gs.aster.arvixe.com/default.aspx The execution time shown makes me feel this code might be the fastest .

{ string sentence = TextBox1.Text;
var sentenceQuery = from sentenceIn in sentence.ToLower().ToCharArray()
group sentenceIn by sentenceIn into m
select new { Key = m.Key, Count = m.Count() };
foreach (var item in sentenceQuery)
{Label1.Text += string.Format("Character: {0} Appears {1} time/s <br />", item.Key.ToString(), item.Count);}}}

Is the lack of response to the C# .NET code I posted similar to a case of: A guy walking into a bar wearing a Microsoft C# .NET T-shirt and challenges any Java, Python etc loving pansy to fight. and The place gets deathly quiet, and one guy in the back of the room slides his chair back from a table, stands up, and glares at the intruder.

Hahaha chill...I'm replying with my phone now...when I arrive my destination I will compare d speed. Let's see if mr c# leaves d bar in a wheelchair

omo_to_dun:
Chei, see as you yab us finish!

Oya make we see if no be the Java, Python etc loving guys go leave the bar with a black eye !

Well this is getting interesting. I have my code too in C on a single line. Now don't tell me about readability, you asked for it Perhaps you can write a shorter one with no lines at all

int main(int i,char**v){if(i>1){int c[26];char *p=v[1];for(i=0;i<26c[i++]=0;while(*p!='\0'){if(*p>=97&&*p<=122)*p-=32;if(*p>=65&&*p<=90)c[*p-65]++;p++;}for(i=0;i<26;i++)if(c[i]>0)printf("%cs=%d\n",i+65,c[i]);}return 0;}

After compiling, launch the exe passing the sentence as an argument. A screenshot is shown below.

hey, that's sleazy!!! Sleazier than what omo_to_dun did with ASCII. In my books, your code is 10 lines. You might consider using recursion to eliminate one loop and using inline if statements like
(x == y) ? Cout << y: cout << x;

@lordZouga: Did you just call the C code "sleazy"? Well, guess what? You ain't seen "sleazy" yet!
Perl. 1 line. 71 total characters. BTW, I don't call this "sleazy", rather "nifty". Got it?

$c{$_}++for(split/ */,lc$ARGV[0]);print$c{$_}||'No'," $_\'s\n"for(a..z)

To test it, pass the sentence as an argument to the script. Eg:

$> perl test.pl "The Quick Brown Fox Jumps Over The Lazy Dog"

Write any shorter and I can't compete!

Can some start a thread with a new challenge...i learnt alot from this one...

Ask and ye shall receive:

ekt_bear: Ask and ye shall receive:
https://www.nairaland.com/1059733/another-programming-challenge

I knew you can't help it...

I enjoyed reading some of the solutions here, howver the most efficient solutions are the one that runs in constant time by creating an integer array representing the decimal equivalents of ascii values in the alphabet i.e 0-127 and initialize all 128 elemetns to 0. Loop through the sentence in 0(N) time and everytime you encountered a letter l. access the L value in the array as array(l) and then increment. Some languages would convert the l to the decimal ascii equivalent if not you can easily do this yourself, time complexity for the conversion is trivial. You could use an hash table but that is overkill considering you only need space for 128 elements. The number of lines of code have nothing to do with the efficiency of the program. I think the solutions written in C would probably run the fastest being native and all

this is not allowed nau...you just crammed everything into one line...

nice code...shortest so far, but you arent rilly supposed to pass any arguements to the program. the rules demanded that you include the default text in the code.

php 2 lines

you can save it in an index file =>index.php

and
query it with the string
index.php?string=The Quick Brown Fox Jumps Over The Lazy Dog

list($alph,$search) = array("abcdefghijklmnopqrstuvwxyz",$_GET['string']);
for($i=0;$i<strlen($alph);$i++) printf("%s %s's <br />",preg_match_all('/'.$alph{$i}.'/',$search,$match),$alph{$i});

To Make the Challenge interesting EVERY semi-colon {except in loops and other constructs} should attract a new line .... i.e the C code pasted earlier
