Yes sir ,the third method you told me to do is very efficient compared to what i had written,but i'm just curious to know what mistake i have made so that i can avoid that sort of mistake,and i'm just a beginner in c programming.

Alright ,i will use meaningful variables,try to help me find out the error here.

sir, code has been updated,yet it doesn't work, after i run the code and after i give all the details as input i get on the display. its not working...what to do now?

sir,i,j,k are the general variables used for running the loop , while p,q are the pointers to the first element of two arrays.I have used all the variables of a particular kind as continuous alphabets to avoid confusion.

that was good and it is 100% correct ,thanks a lot :-)

what i did is i extracted all the digits of the number x and 2x into two different arrays and then sorted those two arrays and checked for the equality of the two arrays...for it i initially created function which returns the number of digits ,if they are equal then i checked furthur by checking the digits else i broke the loop..

i'm sorry @cpallini its permutation not palindrome

i'm extremely sorry sir.It is actually permutation i got confused with the two words..Its not a homework sir,i took this problem from codechef.com/hardquestions section

first input which i defined as number of cases is actually the number of different ranges between which you want to check.And the other two inputs are the ranges for each of the case.I need to find a number x such that x and 2x are permutations of eachother.I need to print all such x between the different sets of ranges in each of the cases.Thanks...there is no error but any nummber isn't being printed..so i am confused if my code is logically incorrect or really there is no such number between the ranges i input...thanks

Sir this is my 3 rd month of c...and I have many other subjects too...so I don't have the time to only concentrate on programming for now...and I'm 18 now and I'm not doing any job of solving any homework problems ...we won't be given any homework and this problem I have taken from our campus web site..which was under part problems for practice ....this is not homework ..I'm here to learn programming and you have helped me many times now....and you suggested Me to use visual studio few months ago....I'm not an expert like you sir and I don't even know the source of runtime errors yet and if I knew I would myself correct them and I'm not that dumb to post the question on the internet just coz of my laze :(

@chill60 codeblocks debugger.exe has stopped working this is the message..so I pasted the code in ideone and it displayed barely "runtime error"

runtime error...

This program is logically complete and i don't understand where the error is coming from ?

First of all this is not a homework..I wanted you to ask you where the runtime error comes from..I mean is it due to the breaks or due to use of more pointer variables ? If you explain me then i will avoid doing that, sir. thanks :) I am not an expert and this is my first program on linked list..

That doesn't stop my app from crashing.and even though we don't allocate space we can assign few values because the addresses are assigned randomly.i.e by allocating space for 1 float value we can store 10 floats or by allocating 0 floats we can store 10 floats.that's not the error in the program.

Please read till the end to find it.

thanks yar ...abhinav :) my 5 *

i guess thats compiler dependent ..thanks cpallini :)

that was awesome...thanks andi.. :)

That's an awesome explanation..thanks a lot original Griff ..

Yes.this is the second week of my c programming..and it was you all who helped me... And I'm 17 and with lots of time free..i don't understand how you find time to answer every question so patiently and with the appropriate solutions with follow up questions..you guys are awesome .. :) .

welcome ...its a fraction of what i had learnt from you till date :)

thanks..in solution 1 i mentioned a program which mentions error without flushing....and gets[^]is better option i have read about it now. :)

in a book "let us c"
the code for which he used it is:
....
...
printf("enter a number:");
scanf("%d",&num);
printf("square of the number is :%d",num*num);
printf("want to enter another number y/n");
fflush(stdin);
scanf("%c",&another);
.....

wow .thanks :)

can you please give me example of where you found it causing error...because in the evaluation process i dont think the teaching assistants would accept anything other than scanf...im restricted to use that with fflush ..so i need to know prior to my labs when scanf doesnt work..thanks :)

I have read in a book on programming that either a space or tab before %d or an fflush is required...some times while coding I find irrelevant results without fflush...I dint exactly remember that code where I has to use.but for most of the normal codes I don't think I use fflush...normal scanf works...so I just wanted to know when exactly it is must ...

I have tried ...I got mtiple printed hello worlds.....I didn't understand why it got printed that many times

yes :)

thanks a lot cpallini ...now i understood what you meant to say...the above explanation confused me... :)

yes you are right.....i found the mistake

awww that works.....i didn't understand what cpallini mentioned above...now what you told is clear..the code perfectly works if i entered the numbers seperated by a comma.........thanks a lot....

sorry :( ...whats the error in my programme?

yes ...i have written the program taking into consideration a

yes pascal ...the above program gives least common divisor..and if one is the gcd then it wont display anything..

Absolutely ...and starting from 1 is not wrong since for relatively prime numbers 1 is the gcd....so we need to start from one ..

i have set minimum to -1 and then compiled using an online compiler now...these are the results i have obtained..
gcd(12,24)=4
gcd(13,26=1)
gcd(3,6)=1
and the online compiler link is http://www.tutorialspoint.com/compile_c_online.php
thanks a lot for the continuous help sir .

13,26....output is 1 :(

And 1 or 0 is displayed irrespective of the numbers entered. Thanks

I'm sorry this programme is to display g.c.d of two numbers...the smallest entered first..

thanks sir :) ill try doing that..

thanks

thanks...but why are you considering the cubeth root here..."??

thanks...if i put the condition as <=30 then is it okay.?

yes @john...there are actually no such numbers thats why there is no output display and when i type in palindrome=i*4 there is output...

:) Yes it is better than turbo c++ which hangs every now and then..

thanks a lot griff :) ..well our course consists of c..i'll download this visual studio.....thanks again...

:)

yes because after winter vacation..we have c language in our semester...and i am enrolled in computer science..so i have started to learn it before hand...i use turboc 4+..and i dont know what to use..i have downloaded this not knowing other compilers :( ..
and why am i getting output as 1 though the input is given as 2 3

i will send you a screenshot.. :( why is it working for all and not for me?

i changed both to %d i get 2,3 and result is 1...i am not understanding what the mistake is!

ok thanks griff...and today is my second day of programming and i'm trying to learn myself...so you cant expect me to be an expert..atleast i tried to complete loops in few hours,..thanks for helping...and btw i don't even know what a debugger is..i have been just into converting all the maths functions i knew into c language...blindly...

@originalgriff please reply! does changing the format working form your compiler?for me its showing value as 1 now..

that didn't work debashish...in my turboc i have done it correctly...here i typed it wrong...i used int-%d float-%f yet its showing 0 or 1 AS output

sorry,here i have given the wrong thing...i have done it using the correct ones..i.e i used int-%d and float -%f ..yet it doesn work..please check it..the entered values are correct but the value shows zero sometimes else it shows 1

that doesnt work...first i did the above thing ,..second time to use decimals in the entered nuumber i changed the code.both arent working

ok,sorry but please tell me what the error is,i compiled this programme in an online compiler and it was displaying prime numbers never ending ,it has crossed 9 digit figure already and its still running..i want to run it in turboc and its failing..plase afzaal try to point out the mistake.

there is no error...but when i run my programme...instead of listing out the prime numbers i get a blank..i didnt find any mistake..please help me out..thanks
