Lec-19: How to Evaluate Arithmetic Expression using SDT | Syntax Directed Translation Example

[@fotatofottu3926]

Small mistake in the right side of tree where T - num - 7 it must be T - F - num - 7

Thank you brother ❤️

Exactly i am going to do that comment but I found that.

trust me , our teachers teach us after learning from you

[@kanakyadav2498]

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😇

Although we pay the university. But the truth is that there is no university in the world greater than KZbin. Because you are on KZbin.

[@khizraakhlak2487]

Thank you so much sir your teaching method is very easy may Allah pak bless you alot of success

[@rananoman3374]

why expand E in 2nd term sir

[@DbCo0pEr]

because there are two '&' operators in the input, so you have to somehow make two '&' in the parse tree. Simililarly for '@'

[@bhaskarsuhag5289]

It means we’ve to expand the tree as much as we have these terminals !

[@madhugarg8383]

Sir why we further expand E

[@lalitkumar8445]

Hi sir, if we apply this bottom up method or short trick on lecture 17 question (5#3&4) then answer will be 35 but your answer is 19 there......pls clarify which answer will be correct one?

[@gauravkodape3169]

Exactly I was also going through this doubt

[@marvashahzadi240]

To much informative lecture THANK YOU SO MUCH SIR

[@moumitamondal1754]

we have to write the steps in exam? or like you did means we traverse the expression? If I use the short technique for my exam will i get full marks for that o i have to do the same you did

[@viplavanand5228]

can anybody explain which rules to take first while making tree is there any rule or we have to make tree according to the input string then how to decide ?

[@toshityagi2018]

Same question

[@3dDigitalArtToday]

see the given input or i should say the "Operators" , see , first use the top or first rule that is 'E=E&T' then after that the first operator that comes in input is '&' so use the rule that has an '&' in it after that on the right side of '&' we have 'T' here, make that T produce an '@' sign using the rule that contains @ in it because the second operator is '@' in the input, now on the left of secound rule we used with & in it , it has a 'E' , make that E produce a number since the given input contains a number in it on the first place and similarly on the right side do the same.......if you got this hint , i guess you know now how to do it.... i'm sorry but i guess i can make u understand better only if you were right here in front of me.

[@as_if]

A bottom up approach helps. Reducing into variables from terminals seemed easier while forming the parse tree.

U thought very well will do with full procedure but I can check my solution with trick

[@ankitagarwal4729]

brillant teacher sir ji

[@Anirbansinha24]

At 3:06 sir how did u put "T -- num" directly?? Shouldn't it be " T -- F -- num"?

[@muhammadtabish6361]

right my question is also same

[@asifhabib9502]

my question is also same , no difference.

[@narendraregar8483]

by mistake

[@RJtheHELL]

He did it by mistake but also when you will put T->F->num ulitmately T will be assigned the same value

CD is of only 4 marks in gate, so I believe this would be enough. Although you should research yourself as well to make sure it is enough.

yeaa

T -> F -> num -> 7 (minor mistake but still)

[@afrozr9191]

Std they gave code

[@parthgoyal9999]

Tree kaise banaya ye to batao bhai

[@AniketKumar-tk4mi]

Bhai any kind of parsing method you can use which are throught in previous lecture Like LR,SLR,CLR OR LL(1)

[@AniketKumar-tk4mi]

For small input you can even visualize it simply without using any parse table or method
