In one example the video has taught undefined behaviour as a operator precedence example

[@tah-seen]

Pre-increment (++i) - Before assigning the value to the variable, the value is incremented by one. Post-increment (i++) - After assigning the value to the variable, the value is incremented. The following is the syntax of pre and post increment. ++variable name; // Pre-increment variable name++; // Post-increment

[@yogeshsanap8453]

Excellent practice questions on increment (++) and decrement (--) operators.Thank you sir.

[@goodboy2528]

The example shown in the video is not taught correctly. If you see carefully the compiler gives one warning about undefined behaviour but the instructor has ignored it. Undefined behaviour should not be taught as an example of pre-post increment/ decrement operator. Although we get output, the same program may cause different output in a different compiler. Search on internet what is undefined behaviour

[@yogeshsanap8453]

@@goodboy2528 Yeah i got your point.I guess not using brackets () may be the reason for that problem.There were 5 to 7 variables used with increment and decrement operator .I guess if you use brackets() for each variable used in that code then that warning may not come i am not sure about it. I was just thinking about it. I haven't tried that yet.But the concept was clearly explained.

[@goodboy2528]

@@yogeshsanap8453 Hey Yogesh it's not about brackets. And example might produce different output on different compiler. To simplify it in C/C++ you are not not allowed to change the value of a variable more than once in a statement. So statement like K= ++i + i++ Tries to change the value of variable more than once. Although this will produce some output and not give error. I actually tried to run the above statement on different compilers. When i=10 I got 23 as output on GCC compiler and 22 as output on Clang++ compiler. You can also try. So you see we get different output for same code. Beacuse of undefined behaviour compiler can do anything it likes.

[@yogeshsanap8453]

@@goodboy2528 Ohh I got it now thanks for your time

[@goodboy2528]

@@yogeshsanap8453 For proof try running the code I have wrote here : repl.it/repls/ProductiveInnocentLaws the output here is 22. Now copy the code in your computer and then run (I assume you have GCC compiler if not then run the same code here online GCC compiler : www.onlinegdb.com/online_c++_compiler Copy paste the code from first link and run on the second link. You will get 23 as output.

[@rajatchaudhary5446]

finally lectures reaching to it's core parts

[@rssszz7208]

From the note some error there I see the issue. The error is due to the attempt to decrement the result of an expression. The postfix decrement operator (`--`) requires a modifiable lvalue as its operand, and the result of the expression `3 * (2--)` is not a modifiable lvalue. To fix this, you can store the result of the multiplication in a variable before applying the decrement. Here's the corrected version: ```cpp #include #include using namespace std; int main() { int result = 3 * 2; printf("%d", result--); return 0; } ``` This way, you first calculate `3 * 2` and then decrement the result.

Hello Team, It would be really great if you put all questions (c++ placement)in one pdf along with solutions (topic wise and difficulty wise).so that students who have already covered dsa part ,and are appearing for interview in a month time..can easily get prepared with it.! Orelse it's tough to follow course when it will bw completed. It will be great for those final year student who have basic programming skills and also completed DSA,and wants to improve their problem solving skills. And want to revise through! . It is a request to you sir.! It will help a lot!! Keep it up for the good content u are providing.. i wish i had it in my 3rd year .till now i would have completed successfully.! Thanks, Regards!

Question 4 and 6 will give lvalue compilation error, as increment and decrement operator (++ and - - ) will work only on a variable and not on a constant ie; a++ or a-- is correct, but 2-- or 2++ is error.

[@hellknightgaming8472]

But Bro its c++. you have to define what is 2. Bro listen u see 2 has a value of 2 and when u use decrement or increment 2 get some other value. which is not possible in C++👍. I hope my explanation is correct
