C/C++ Coding challenges

[Enigma_1]

oky onna next challenge eka. C/C++ program code ekak denna date ekak dunnama (year eka 1899 ta wada wadi date ekak) weekday eka mokakda kiyala denna one.
for an Eg

Please enter the date (dd-mm-yyyy) : 30-07-2010 - user input eka
This day is Friday. - Computer response eka .

okay here is my solution

#include "stdafx.h"
#include <time.h>
#include <stdlib.h>
#include <stdio.h>
#include <string.h>

char* dayInput =NULL;
char* temp;
tm structTime;
char * days[] = { "Sunday", "Monday","Tuesday", "Wednesday","Thursday", "Friday", "Saturday"};

int _tmain(int argc, _TCHAR* argv[])
{
    printf("Please enter the date (dd-mm-yyyy) :");
    dayInput =(char*)malloc(11);
    scanf("%s",dayInput);
    temp =(char*)malloc(4);
    structTime.tm_mday = atoi(strncpy(temp,dayInput,2));
    dayInput = dayInput+3;
    structTime.tm_mon = atoi(strncpy(temp,dayInput,2))-1;
    dayInput = dayInput+3;
    structTime.tm_year = atoi(strncpy(temp,dayInput,4))-1900;
    mktime(&structTime);

    printf("it is %s.\n",days[structTime.tm_wday]);
    system("pause");
    
    return 0;
}

here I have used only tm structure and mktime() function. both of them are defined in the time.h. I have notice that many C/C++ ppl framed to stdio.h,stdlib.h,iostream.h,conio.h.. but guys there are lots of other headers in C runtime. just check them out. I will put my next challenge soon.
Thanks

CoOOoL thread bro(hope u r a bro.. ).. keep it up...

May I give u an idea..?? why don't you expand this thread to other languages also, like Java, VB and some scripting languages (PHP is my fav.)

I think it will be great for all the people who stick with different kinds languages.

And mind you.. it will attract many people (who r doin some sort of programming or IT related studies) towards Elakiri...


It will definitely attract the IT students who desperately look for solutions and clues for their assignment.
GT will be very grateful to you for new members..

+ rep..

Thanks for the post. Its a grt idea machan. But I code only with C/C++ and C#. I knw little bit of VB 6.0 and VB.net. But I don't know PHP,java..... Yes from now on you can use any language. bcoz it doesn't matter what language that you are using. you have to think for that specific logic. But I need your help guzz. Another thing is any one can post a challenge here. So this will be an open thread for every one. if you have any assignments , challenges , just post your questions here.

 

[amilabanuka]

nice thread machan...

 

[Enigma_1]

.. these are baby logics lets do something like face recognition

If ur really think that your good at with heavy maths, image processing, then go n start a new thread for this. I will give my support every way I can

OK.. gr8..... don't worry machan.. I'm sure there will be lots of EK'ians doing different lang's & they will make sure this thread goes on..

I'm little bit busy these days, hoping to post some challenges ASAP.

Best of luck for one of the coolest threads in EK.

not heavy math.. but image processing and heavy logic..

.... eeka algorythm eka anuwa thamaa.. simple face detection thiyanawaa .. sarala AI and code ekak thiyennee.. godak complex eewath thiyanwaa..

unfortunately in my degree there is no AI ... hope to find it in Msc...

whats ur degree.. ?..

 

[Enigma_1]

not heavy math.. but image processing and heavy logic..

I didn't do double math for my degree.I did only single maths. AI was there in my IT degree. I did it. So why don't you give us the start. You have the interest on this. We will start from a simple application. Then we'll improve it. You have my full support on this.

ok guyss next challenge
Write a program to show the hexadecimal representation of any given integer.For an example program will look like this


Please enter the integer value : 5498 - user input
hexadecimal representation of 5498 is 0x157A. - computer out put

remember this is an open thread for any programming language
good luck

does this program involve with huge maths....

 

[Enigma_1]

it depends. As far as I can see you got 3 ways to do this

 

[Enigma_1]

I'm really sorry guyss. you got only 2 ways to do this. (As far as I can see)

In java

package integertohex;

import java.io.*;

public class Main {

  public static void main(String[] args) throws IOException{
    BufferedReader bf = new BufferedReader(new InputStreamReader(System.in));
    System.out.println("Enter the decimal number:");
    String hexval_1 = bf.readLine();
    int x = Integer.parseInt(hexval_1);
    String hexval_2 = Integer.toHexString(x);
    System.out.println("Output in hexadecimal: " + hexval_2);
  }
}

don't know C++ much

ha ha... i think using inbuilt functions are not acceptable.

 

[yrollgayanth]

ha ha... i think using inbuilt functions are not acceptable.

come on dude it's free to use

 

[Dileepa.]

come on dude it's free to use

ha haa i knw machan ...
but the thread may satisfied with algorithms i think...
