This playlist is the whole semester syllabus and we don't know how to thank u but always there with us .
Education 4 us

[sudipsen]

I think this is the only playlist where I found all my concepts ...Thank you for the efforts you give to make videos without any benefits ...

Thank u so much ma'am. Completed whole playlist by leaving a few videos here n there but, this playlist was the closest one to the actual syllabus✌❤

7:47 return statement is redundant because it's return type is void, and printf is a valid statement.

[zackdaspy]

Thanks for this Wonderful Playlist! Quite helpful for exam preparation.

[UNIQUE-SRINIVAS]

thank you so much mam, iam very happy with your explination may god gives you a great future once again thank you so much.

[jaswantjatoliya]

😊Thank you so much✨mam for this playlist and also for give your valuable time...👍

[VinodKohli]

Mam one doubt in the unreachable code explination it not be void add_ten(int x) it would be int add_ten(int x) otherwise return statement will not work mam and you are saying that return was happened and print was not executed. please check it once mam

[pranayansaha]

here in the unreachable code example...the return type is void...so it cant return ...right??rather printf will work here i guess...mam can you please explain that??

[bompallypreethi]

is peephole optimisation is same as local optimisation

[hralch]

Thank you for all these videos! Could you please explain "Backpatching for Boolean Expressions" and "Register Allocation by Graph Coloring"?

[manasatadigadapa]

Nice explanation ma'am thank you so much ma'am

[Rameshmaddisety]

10:40 it's not a=a+1 it's a++ 🙏🙏🙏🙏

[SRIDHARANKCS]

4:24 "i want to be eliminated" 🤣🤣🤣

[kumarrishabh]

Accding to me the last one would not be a = a + 1 !!!! It would be a = a * 1
