[@huzaifasideeq5249]

Sir please upload all the remaining notes,your notes are very helpful

[@eastonronan18]

I guess I am quite off topic but do anybody know of a good place to watch newly released movies online?

[@frederickbilly5009]

@Easton Ronan i would suggest Flixzone. Just google for it :)

[@pierceedwin5273]

@Frederick Billy Yea, I have been using Flixzone for since march myself :D

[@eastonronan18]

@Frederick Billy Thank you, I went there and it seems like they got a lot of movies there :D I really appreciate it!!

[@anuragchowdhury4101]

Honestly, I have ZERO problems with your repeated use of rights unlike others in the comment section because you are teaching me for free in the best way possible. That's all I can ask for. Keep it up bro !!

[@labibanik6613]

Loved the way you explained everything..and i appreciate your effort...but please, please stop saying right...i got a headache from your "right".

[@LearnVidFun]

Hey buddy...Thanks a lot for your appreciation and suggestion!! Will take care of it next time...Keep learning :)

[@atulpapneja832]

thnks you this video is so helpful for me becous i done question of 10 marks in my exam by this video thanks you again :--) :-)

[@LearnVidFun]

Woow!! Glad to hear that buddy...Keep growing!! All the best...Keep learning :)

[@VwebDev679]

THANK YOU FOR THE CLEAR EXPLANATION , At 29:05 in (1) and (3) , I think the 'c' operand should occupy the arg2 instead of arg1 , as the three address code has format of result=arg1 op arg2 ..

[@coder040]

"Right" instruction ka common subsequence optimization karna padega 😅😃

[@PratikSailor]

In Illustration 2 , Why is ( b*-c ) calculated twice. I mean can't 3 address code be as follow ? T1 = minus c T2 = b * T1 T3 = T2 + T2 a = T3

[@LearnVidFun]

Of course it can be!! The point is the TAC I have written is not optimized!! During optimization, redundant statements will be removed! I hope that was helpful :)

[@PratikSailor]

Yes Yes Yes. Now I completely got the idea. Thank You Sir :)

[@tirthankarsarkar4206]

My examination is tomorrow, and you are a saviour buddy. Thank you so much for the effort you put in to make the concepts clear. I watched your videos in 1.5x speed as they are quite lengthy and I'm running short of time, yet your lectures were perfectly understandable. P.S: Your handwriting is superb! Keep up the good work. :-)

[@LearnVidFun]

Hey buddy! Thanks a lot for the appreciation :) We will keep putting efforts to provide you such content! How was your exam? All the best...Keep learning :)

[@tirthankarsarkar4206]

LearnVidFun My exam went quite good, all thanks to you :-)

[@LearnVidFun]

Great! Glad to hear that! We would love to assist you in future as well! All the best...Keep learning :)

[@pranav1576]

who is the singer in your dp? I have seen him but can't recognize

[@LearnVidFun]

Hahaaa! That's me buddy :D And I am not a singer :P

[@saurabhshrivastava224]

His hand writing is pretty good. Right?:)

[@LearnVidFun]

Hahaaa...Right! All the best...Keep learning :)

[@vishalkrishnaag2860]

which is a computer font

[@DeepikaSingh-io3ou]

please try to speak less no. of "Right".... it is quite annoying... otherwise the video is helpful

[@LearnVidFun]

Hey dear...Thanks a lot for your appreciation and concern....Thanks for watching...All the best....Keep learning :)

[@technomissilecraft4532]

Right

[@gautamchoudhary7529]

hahahaaa

[@piyushkantmaav5995]

right

[@VikasYadav-fu8cq]

Yeah lul

[@Nshree282]

in eg.(2) ...precedence of operators is as: unary minus, binary *,+ and then =(higher to lower) so, step1: both -c will b assigned to register(as u r using different registor for both ) t1= uminus c t2=uminus c step2: * operator (associativity left to right) t3=b*t1 t4=b*t2 step 3: + operator t5=t3+t4 step4: a=t5 is it right?? and is it the same thing as u hv done? can we also write 3-add. code as following: t1=uminus c t2=b*t1 t3=t2+t2 (if we use one registor for both -c as u hv done in previous (following)problem.. -(a*b)+(c+d)-(a+b+c+d) for both (c+d) u used same registor? plzz clarify!

[@LearnVidFun]

Hey dear... Yes! You can do it this way also...It's just that the three address code I have written is not optimized!

[@Nshree282]

ok! thank you :) :)

[@VC-kj9yx]

i had the exactly same doubt

[@VC-kj9yx]

nipani t3=b*t2 not t1 as unary is right associative and * is left associative due to * you will evaluate left * first and so left unaryminus c too

[@vaishalithakur7298]

Your videos help me everytime. Nd when you say "RIGHT"... that was so compelling. Thanku

[@shubhankkushwaha5017]

Yes it's helpful

[@thesshivam85]

a drinking game can be made on those "rights" 😂😂....good explanation though

[@LearnVidFun]

Hahaaaa!!! I know buddy... :D

[@adityasinghaswal4923]

ya right

[@meghnajain7889]

Great effort...Your wonderful explanation overpowers those trivial things mentioned by some of the people out there...Keep up ur good work👍👍👍

[@ronitsingh6765]

In illustrations 2: in location 6- for ARG1 you have taken t5 but in triples representation in ARG1 you have taken (a) and in Arg2 you have taken 5 why? It should be 5 on the location 6 in triples... Plz check and tell me

[@Nshree282]

for unconditional jump , result is: label and operator is: goto , i got this much but in conditional jump also do we need to keep the arg1 and arg2 field blank?? eg: if a>b goto L here 'a' and 'b' are present as an operator , are we not going to use these in quadraple representation! please clarify this?

[@LearnVidFun]

Hey dear... The reasoning for the intermediate code for IF statement is similar to the reasoning used to implement such constructs into assembly language. For example- IF A

[@Nshree282]

got it :) thank u so much for such a clear explanation.

[@LearnVidFun]

Happy to help you...All the best...Keep learning :)

[@rizwanataqui2907]

In second illustration...why are we repeating the code for same sub-expression?I mean can't we write t3=t2 and then t4=t3+t2?

[@sushanth6039]

If x>y then goto(5) how to represent this as Quadrapule. Here 2 operators are present > and goto

[@parthnyati9695]

can you explain how to store statements like "if a > b goto c" in triple representation

[@LearnVidFun]

Hey buddy...I will definitely try to provide it soon!! Stay tuned...All the best...Keep learning :)

[@ravitiwary6894]

Sir why we've included '=' sign in the operator section in the last qn location (6) of quadraple?

[@neetumehra7580]

sir there is complete notes on compiler design??? and now gate syllabus of compiler is updated or more topics are added.. please provide the full complier video lectures .. your lecture is amazing..

[@shubhankkushwaha5017]

Go-to asha khelri lecture

[@johncarter7930]

hello is this right three address code for this expression a=b*-c+e*-d t1=uminus c t2=uminus d t3=b*t1 t4=e*t2 t5=t3+t4 a=t5 kindly reply

[@LearnVidFun]

Associativity of unary operators is from right to left... t1=uminus d t2=uminus c t3=b*t2 t4=e*t1 t5=t3+t4 a=t5 All the best...Keep learning :)

[@changumangu5228]

sir is that needed to write the temporary varibles for the uminus c for the two times insted of one?

[@LearnVidFun]

Hey buddy... No, that is not at all necessary...If any statement in the TAC is written more than once, then it just means that the TAC is not optimized...After code optimization, the statement will appear only once if it's all same. I hope that was helpful.. All the best...Keep learning :)

[@amirshah-gt9jj]

great Explanation... You have Worked Really Hard on core concepts. Keep Up The Good Work.

[@LearnVidFun]

We are glad that you are liking our efforts! We will keep providing you such content! Stay tuned :) All the best...Keep learning :)

[@kapilsharma7276]

You saved my life. Thanks!

[@junaidhassan8093]

well just saw a few comments of peoples and feel bad for them because they cant see the effort,well bro thanks alot for this topic you explained brilliant Thanks alot GOD bless you.

[@LearnVidFun]

Thanks a lot buddy for the appreciation! I am glad that the videos helped you! All the best...Keep learning :)

[@VC-kj9yx]

isnt your three address code wrong in illustration2 you first solve unary operator -c on rhs as unary is right associative then you should t=b*t1 is correct but after that why you ar again using t3=uminus c it is already done in t1 -c is same you can simply do t3=t2+t2 and a=t3 why extra steps?

[@LearnVidFun]

Hey buddy...If you want to write that way...you can!! There is nothing wrong in it.... The point is the three address code that I have written is not optimized...After optimization, the redundant statements will be removed... I hope that was helpful :) All the best...Keep learning :)

[@DeepakKumar-pm7ie]

Right sir 😀

[@anilladha3314]

Nice explanation. ..& hand writing. ..Thank u...

[@travelnlearn]

Very well explained 🔥

[@yashanand4313]

the explanation and handwriting both were very good. Right??

[@aryamukherjee2443]

Sir you nailed it.. super super super like.. Sir can u reply once that is it possible for you to make a video on syntax directed translation or not ! i require it.. if possible pls reply

[@LearnVidFun]

Hey buddy...Thanks a lot for your appreciation! I will definitely try to make the video available soon...Stay tuned! All the best...Keep learning :)

[@pradeepkumar9586]

Thanks a lot dear! All the best...Keep learning :)

[@vishwajeetsingh5646]

LearnVidFun Same to you , you are doing a great job 😊😊😊😊😊

[@AMITMATHEWBCI]

why are we using T3=uminus c again as we already have T1=uminus c,can we use T5=T2+T2? great explanation

[@kiranvishwakarma4870]

Thanks so much .. Great way of teaching ...

[@tusharshivan9559]

Suppose lets say that, this is the intermediate code, t1 = inttofloat(60) t2 = id3 * t1 t3 = id2 + t2 id1 = t3 and the code optimiser optimises the code and it becomes, t1 = id3 + 60.0 id1 = id2 + t1 then my question is, why don't the "intermediate code generator" doesn't directly generate optimised code?

[@prakritisingh7790]

Very much helpful for studies thanks alot☺️

[@shivaniagnihotri8406]

thanks sir your videos are amazing. can you upload the optimal binary search tree in dynamic programming.

[@LearnVidFun]

I hope you understood the concept pretty well! All the best...Keep learning :)

[@s.sairevanth5063]

Clear explanation...

[@aishwaryas5847]

Your videos are really helpful.....could you please shorten the duration of video speaking to the point...Thanks!

[@LearnVidFun]

Hey dear...I can perfectly understand what you are conveying!! But there is an option of increasing the speed...So, you can use that!! Actually, I have to take care of all kinds of students- fast learners as well as slow learners!! I hope you understand :) All the best...Keep learning :)

[@foodiezz_mini_vlog]

Thanks sir🙂.I like your way to teaching ..... please sir I request you .... compiler design subject ke sare numerical topics ke lacture provide kr digiye sir because lockdown ki wjh se hmare study me bauth problem aa rhi h so sir please aapke lactures mujhe bauth pasand h so please sir compiler design ke sare numerical topics ke lacture digiye.🙂

[@dhruvbaria5985]

why are all the people asking for notes? You can write imp points while watching the video. Btw great work Buddy.

[@LearnVidFun]

Hey buddy...I really appreciate your way of learning...You are right!! Everyone should make their notes themselves...It enhances their learning... All the best...Keep learning :)

[@vijayakumararumugam2755]

why are u storing -c in 2 different temporary values..?

[@LearnVidFun]

Please mention the timing and question number so that I can help you.. :)

[@vijayakumararumugam2755]

Illustration2 : @27:20

[@vijayakumararumugam2755]

LearnVidFun Thanks man!!! i will check the blog :)

[@vijayakumararumugam2755]

Thanks man

[@LearnVidFun]

Ooh...Buddy..This is because it is in accordance with our three address code that we have written and the three address code that we have written is not yet optimized....So, it is perfectly fine if you are doing this way in your exams as well....!!! Even if you write the optimized code and then make representations for that...then also anything won't go wrong..I hope you got the point... :) Buddy...Do you Know..Now, I have transferred all these video notes onto a blog which I have created recently...So, please take your time to visit the blog and get the notes..The link for the blog is- learnvidfuncompilerdesign.blogspot.in I would love to help you in case you need any assistance...All the best...Keep learning :)

Happy to help you dear! All the best...Keep learning :)

[@triggersharma2311]

Yes you are right

[@freethinkers3680]

very good explanation

[@sheetalbhandari7504]

how you made indirect tripple table.. and from where 36,37,.....40 came in first column

[@LearnVidFun]

Hey dear.. 35,36,37... are just the arbitrary memory locations...You may take any according to your choice but they must be in serial. I hope that was helpful.. All the best....Keep learning :)

[@aditichowdhary5221]

In the second illustration I didn't get why we have taken uminus c=T3 why not uminus c =T2 as unary operator must be taken first.

[@LearnVidFun]

There would be no issue if you do it that way also! The code we have written is unoptimized and there is actually no need of the third and fourth statements as they are redundant statement! During optimization, they will eventually get eliminated! I hope that helps :) All the best...Keep learning :)

[@aditichowdhary5221]

LearnVidFun OK thank you so much

[@umairsaeed5055]

well explained Right!
