illustration 2 please btao u are wrong ?? t4 = t2 + t3 should be right ?

[@LearnVidFun]

Yes..You are right! It is t4 = t2 + t3 and not t4 = t1 + t3. The correction had already been mentioned as a note which appears on the screen at 19:41 minutes. I think you did not notice it probably because your annotations were off that time! I would suggest you to always ensure that your annotations are on every time whenever you watch any study video on KZbin so that if there is any correction mentioned, you can get to know of it. All the best..Keep learning! :)

[@onepath8122]

you are very good teacher . you know how to transfer the information

[@maheshsolanke480]

it is true or not for last illustration if a

[@LearnVidFun]

No buddy, that's not correct! Consider the statement (4), If the condition c < d satisfies then the control will go to statement (5) and also if the condition does not satisfy even then the control will go to statement (5). So, you must write an unconditional goto statement at statement (5) which send the control in such a way that t=1 is not executed.. So, always remember a thumb rule- "After every conditional goto statement, unconditional goto statement will follow" and in this way you will never commit a mistake! I hope that was helpful... All the best...Keep learning :)

Thanks a lot for your lectures. Very "to the point" explainations. It would be great if you provide a scanned copy of your pages with every lecture. Only if you think it is a good idea, you may add a Google Drive link to your discription

[@LearnVidFun]

Thanks a lot buddy for your appreciation.. :) Adding a Google drive link is a good idea but soon I dropped it because I felt that some students might not be comfortable with it...Anyways thanks a lot for the suggestion...If you feel it would be great...then I will definitely give it a try... Meanwhile you can provide your email address so that I can mail you the notes.. :)

Amazing Handwriting bro........

[@LearnVidFun]

[@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?
