Post your C/C++ Programs Here

Re: Post ur C/C++ Programs Here

Are you kidding me? If you'd said Windows I'd have understood the pain. But ... your linux has no compiler? I wouldn't even use it then

And we definitely need some sort of a syntax highlighter plugin if a new Programming section is being proposed.

Couldn't test it as I am on Linux right now and Have no Compiler installed here.

can u ppl plz give me the code to convert any decimal no into a binary no??
in C

That's a weird statement. gcc is one of the foremost things that is needed to install my distro.

@aditya.shevade It's very cool ans.Gr8 job ...I was just looking for this ans.
Now do the same thing without using "()" .

I tried to do it using bitwise operators, as per your hint. But could not ..... Maybe I am too tired today. Will try it later tonight and see. You please don't post the answer.

(To others, I just told Projjwal , not to post answer. Not to rest of you..... Just in case...)

Re: Post ur C/C++ Programs Here

GCC is not included in the default install of Ubuntu btw

does anybody had c++ code for converting text to speech

you mean someting like this ?

using System;
using System.Speech.Synthesis;

namespace HelloSpeechSynthesis
{
    class Program
    {
        static void Main(string[] args)
        {
            SpeechSynthesizer synth = new SpeechSynthesizer();
            synth.SpeakText("Hello, world!");
        }
    }
}

It's in C# though

well is it possible to program the matrix(the falling numbers in the movie) type programming using c++.

@The Binary Search program

doesn't wrk and note tht binary search is only fr sorted arrays

Re: Post ur C/C++ Programs Here

@ qwerty, cool programs, and actually the program executes but it, think u enter some values to perform the given task. it does but that dos window will close before showing the output. but when i run it again, i can see the output. help

Dyne;bolic, custom edition..... [I am not into linux though... My studies require me to stick with Windows.]

Just found a module for programming though...
Now going to use it.

Arre yaar.. read what I previously written...
You will need to press Alt+F5 to view result...
Alternatevly use getch() function just before the end of program (just before "}" , you will need to include 'stdio.h' file in C++ program for this.)

Hope you get me this time.

getch() needs conio.h ,getchar() needs stdio.h

I had given up. So I checked....

By the way, can you please explain the working of this? I have no experience whatsoever in bitwise operators And I have a laptop, and the viewing angle was such that I was able to look at the answer without selecting it.

But, digital logic.... I have quite some. So, at lest explain in a logical, if not precedence level manner.

I had no idea that you can use a^=b in C/C++ program....

you should read "The Annotated C++ Reference Manual" by Stroustrup , it gives you really handy tips n tricks and advises you on Efficient Programming styles .

Re: Post ur C/C++ Programs Here

^^ Alright. Currently I just finished through that Balagurusamy book, skipping the template programming. The book is OK. Not too good.

So, I am reading professional C++ by Solter and Klepper. And I really like that book. It's upright professional as the title says. The way it explained classes when compared with Balagurusamy's explanation... Balagurusamy is not at all very good.

Re: Post ur C/C++ Programs Here

@Yamaraj gr8 job 10out of 10

-----------
a^=b^=a^=b is the answare
here ^= means bitwise XOR operation
I am describing it through an example .
Suppose a=12 ; b=32
Now,for bit wise operation convert it to binary
So,
a=001100
b=100000
now,
in ' C' operation done on right to left direction
So, start it from the right most side.
a^=b it's mean a=a^b so, a=001100 XOR 100000 =101100 but the value of b unchanged b=100000
next part
b^=a it's mean b=b^a so, b=100000 XOR 101100 =001100 now the value of a =101100
last part
a^=b it's mean a=a^b so, a=101100 XOR 001100=100000 now the value of b=1100
Now the new value of a & b is
a = 100000 = 32 in decimal
b = 1100 =12 in decimal
--------------------The Full C code is---------------
#include<stdio.h>
#include<conio.h>
void main()
{
int a,b;
a=12;
b=32;
a^=b^=a^=b ;
printf("\na=%d",a,);
printf("\nb=%d",b);
getch();
}
--------------------------------------------------
@Nav11aug
Not the look of program/algo says this program/algo is good this bad.
the complexity (time,space) of the program/algo decide which one is good & which one is bad.

Re: Post ur C/C++ Programs Here

^^ Ow.... those were the shorthand syntaxes..... Alright.... Fine. Understood.

I did not know that bitwise XOR will work bit to bit for every bit.

One last question. What steps did you use to arrive at this logic? I mean, the method used to find out the exact sequence of operations for the change? Did you use any simplification method, like we use k-map or what?

Aditya

 

[Projjwal]

Re: Post ur C/C++ Programs Here

no not k map.XOR is exclusive or means for odd numbers of 1 out put is 1 & for even numbers of 1 output is 0.
now the logic is
1 xor 1=0 xor 1 =1
1 xor 0 =1 xor 1 = 0
0 xor 1 =1 xor 0 = 1
now
0 xor 1=1
1 xor 0 =1
1 xor 1 = 0
sum up formula: a xor b =answer xor a = b
and answer xor b = a
from the ^^ lines u will get a logic that answer of xor between two numbers & xor between answer & any one of the number gives the other one . It's the main logic. so, if u define it in bitwise it will create the algo .

**Here I describe for 1 bit only this operation is happed for all the bit of the number .thats way swap done.
