Exactly that is what I was about to comment . Or you can say if we follow the tree structure then the + operation will be perform earlier the * operation .
6:12 + production is defined below the production of * so it has higher priority than *, as a result the answer will be (5*(3+4)) = 35. Please cross check!!!!!
just wait for 2-3 days and see how your subscriber count will take a huge jump. becoz its exam time here :) (and you deserve every bit of it) you are our only hope in exams. THANK YOU FOR DOING GOD's WORK.
When grammars are annotated with Semantic rules, we can club Syntax analyzer and Semantic analyzer phase into a single phase. So we can create the syntax tree and verify the semantics at the same time
So, finally i got a one stop solution of my compiler design examination. Firstly, due to this pandemic, neither we could avail the books nor there were proper video lectures available on youtube to help me out in this subject. One of my friend suggested me this channel and surprisingly, watching the first video of this video series, made me realize that its going to be enough for my complete subject. The way this teacher has explained the concepts, his clear understanding as well as the clear vocalization of the subject had a huge impact. No doubt, this is the best of the series, i have ever watched in terms of Engineering subjects. No words to express my gratitude. Students like me who love to reach in depth of a subject, you have given a one stop solution. I cannot stop ravishing and thanking you "SIR"🤩. God bless😇
Sir ek doubt hai plzz reply me as soon as possible Aap sir kisi example mei "&" ko "+" consider kr rhe hoo Or kisi example mei "&" ko "*" I can't understand what will i consider in some other questions plz reply me if its possible
please sir make and complete a playlist in software engineering .... and make a software modeling (UML) tutorial basic to advanced ... please sir ....please
You have to assume two more semantic rules in order to get 35, viz. S -> A {S.val = A.val} A -> B {A.val = B.val} If you assume the semantic rules as given in the example, i.e., S -> A {S.val = S.val * A.val} A -> B {A.val = A.val + B.val} then 5 # 3 & 4 becomes 0, assuming initial values of A & S are 0; otherwise the value of the input expression cannot be determined. In the 19th lecture, Sir included those two semantic rules that I've written at the top.
Sir, O/P will be 35.
According to the grammar's rule, + is having the highest priority than *.
So, 5*7 = 35.
Yes
@ Grow ad yes answer will be 35 according to SDT
Yes output will be 35
Yes

Sir aap kya all rounder ho 😅😅 her kuch padha dete ho
Not satisfied with this video 😅
The answer for this should be 35 and not 19 because the precedence of operators increases as we go down the parse tree.
yep
Thanks buddy I didn't know anything about compiler design😂, I would have just followed his answer 😭. Please correct the mistake in description sir.
Sir ans is 35
According to bottom up approach ist addition then multiplication
Sir kia hmy question me rules or cfg ya given hoga ya srif string ?
First liked your video then i started watching it. Respect you alot sir ji
Haattt bhag yaha se

+ production is defined below the production of * so it has higher priority than *, as a result the answer will be (5*(3+4)) = 35.
Please cross check!!!!!
Sir in last question answer is 5*(3+4)=35 according to how you have drawn the parse tree.
I wish I could understand Indian accent.
sir aapko itna saara kuch kaise pata hai?

Sir pahle + kyon nahi hua?
I think + has higher precedence.
True o/p should be 35.
Yes
Great teaching. You always nail it.
Stay Blessed Brother ❤️

I can't understand what will i consider in some other questions plz reply me if its possible
❤❤❤
Sir. Apko. Maths. Nahi. Aati. Kiya. 😅. Multiply. Bhai. Nahi aata. Sir. Apko
Great Teaching. Just clarifying that the answer to the last question is 35 rather than 19 because & has more precedence than #
please sir make and complete a playlist in software engineering .... and make a software modeling (UML) tutorial basic to advanced ... please sir ....please
@khalida didi apki ab tab 8th semester khatam ho chhuka hoga 🤔 can you guide me please didi 😞

Most awaited video🔥🔥☀️☀️
Hello sir. Woh last mai tree ke according, + pehle krna tha. Toh, 5*(3+4) hoga woh shayad. Matlab 35.
Sir the output will be 35 as first we have to add 3&4 =7 then multiply 5#7 =35
No he did it correctly the output is 19
@@sitcj No. + is lower than * in the tree. Hence of higher precedence.
Sir, according to your 19th lecture and grammer's rule ans. should be 35 becoz of + has higher priority...
Sir, plz clear the confusion🙏
You have to assume two more semantic rules in order to get 35, viz.
S -> A {S.val = A.val}
A -> B {A.val = B.val}
If you assume the semantic rules as given in the example, i.e.,
S -> A {S.val = S.val * A.val}
A -> B {A.val = A.val + B.val}
then 5 # 3 & 4 becomes 0, assuming initial values of A & S are 0; otherwise the value of the input expression cannot be determined.
In the 19th lecture, Sir included those two semantic rules that I've written at the top.
thanks sir for being consistent we love u
Sir & having higher precendance than # so & calculated first so acc to me o/p should be 35.
why is & having higher precedence, please clear my doubt
thank you so much :)
3:21 practical part of video starts here. before this, it's theory
Thank you for teaching in Hinglish
The result of the parse tree is 35.

sir hair styling tips dedo....padhana vadhana toh hota rahega.
Thank you
Third phase semantic analysis phase meaning chaking
Wrong answer. output will be 35 because '+' has more precedence than '*' according to the grammar.
* has more precedence than +
@@khilii conventionally yes, but here it is opposite because of the grammar rules

Thank you sir
+ will be calculated first then *
accoding to the parse tree it will be 35
🤣2:11 you can write whole story on paper😃😃
Sir please make video on dependency graph
wow i dont know hindi but u r teaching was insane
Sir according to parse tree answere 35 hai

Ok, that's not English.
Killed it 🔥
Thanks sir
Sir plz theory bhi bataya karo sir
answer should be 35
Sir,please upload more video of compiler design
Answer is 35 not 19
Thanks a lot Sir!!!😊
Thank you so much sir for this video 😊😀 ... You are an amazing teacher ☺️.... Hat's off to you 👍👍
In Which sem r u currently in !?
Sir Answere 35 ayega.
Very helpful
Sir please upload all this lectures asap
Nice explanation
Sir live start KRiye sir
Thank you sir 🙏
thanku sir ......for giving such a amazing videos for learn
35 is correct
Thank you sir
No problem
according to the tree it should have been 5*(3+4) -> 35.
Need next video ASAP
Tqs sir
Greate teaching
Thanks sir
thanks sir
Huge thanks to you by learning from your many playlists finally im just about enter in final year of BS ♥️♥️
