This is the BEST c programming channel i have ever seen . Also i will recommend to my other friends . Fantastic tutor !!! I have one small request , could you please upload C++ programming videos ?
For the last question:- 1)If you set the code like this in the complier: #include int main() { int a=4, b=3; printf ( "%d", a++ + ++b); return 0; } Then the output is :- 8 2) But , if you set the code in the compiler like this: #include int main() { int a=4, b=3; printf ( "%d", a+++++b); return 0; } Then , there will be an error! Thank you guys
First program is correct, it will not raise any error. And the last value is 8. Explanation: a=4,b=3; are the values we have , a+++++b means the lexemes are |a++| |+| |++b| . So 'a' is used and incremented to 5, and b is incremented to 4 and then used in expression. So the final answer will be 8. Second program will generate error because immediate after an increment or decrement we should have a variable
@@manu-mp5bt but the question doesn't have spaces and "error" is one of the answers so I believe 8 would only be right if spaces you showing were part of the written program. please do correct me if I'm wrong. otherwise d is the right answer for me
You rock guys. Keep it up 👍 And yeah the answer to the homework question is d)error. Had it been written with a space as a+++ ++b, the answer would have been 8. But as it is, i.e., a+++++b, it is evaluated as |a| |++| |++| |+| |b| or (a++)++ + b which causes an error because an an increment operator doesn't take an rvalue or a++ as its operand. As discussed more clearly by neso, both increment and decrement operators work only on lvalue(left value).

Answer to the question is ERROR. As a+++++b is tokenize as - a ++ ++ + b = (a++)++ + b So, as increment operator can take only lvalue so, compiler generates error.
One of the super duper channel which I had never seen over the years. When it comes for vocalize, we can't express it out. Finally it is a student friendly tutorial.
@@pineapplee101 lexical analyser scans longest and valid Tokens ..there we are given a+++++b and if we generate tokens we get 'a' ,'++' ,'++', '+' , 'b'...
Comments for myself: lexical analyzer scans the code and tries to find meaningful sequences which it converts to tokens to translate. Usually, meeting a blankspace will stop the current token generation. Post-increment happens after the current value of the variable is used in the function. My answer for the assignment is d) error We first need to get the sequences of tokens to get an overview of what's about to happen. The sequence of tokens is [a] [++] [++] [+] [b]. This might seem to work, but if we try to go thru it one by one. a++ is fine, but a++++ is not. a++++ may seem valid but ++ operator requires to be accompanied by an lvalue. a++ is an rvalue hence, an error will be thrown at that point.
I have enjoyed these lessons immensely. Your combined approach of discrete, literal and figurative explanations is more comprehensive and is more effective in building a stronger association for understanding the subject. The value of your understanding is made more accessible through clear instruction and is accomplishing its intention and multiplying into others being able to understand it as well. That's good teaching. It's a skill and a gift. Thank you. It's inspiring. I am a US Citizen, born and raised. I have benefited greatly from this resource. Thanks for your willingness and ability to share.
Output = 8 a, ++, +, ++, b will be tokens generated by lexical phase As ++ is a unirary operator so after first ++ is generated second ++ won't find any variable near it so it backtrack to + only and then ++ will be generated next token bcz it will find b as nearest variable.
I have studied C language earlier and I started thinking that I know everything but this channel makes me realize that I know everything of what was taught not everything about c language.No other youtube channel has cleared concepts this way with so many logical examples. I feel quite fortunate that I got to know about this channel in the 2nd-semester only after ruining my basics earlier by studying from other so-called famous TH-camrs.One humble request is there any book required for C language for gate prep or your videos and previous years is enough? I'll be grateful to you if you reply. If you find some words in my English rude then sorry for that because I am in earning phase
In each and every video it seems that you are opening some parts of my mind, I am learning some new things in every video. Thank you very much sir for these amazing videos.
May be they are some other c teachers... 😅😅 who dont know how to teach... And they are getting jealous of our sir.... Those who dislike these videos are really fools...
some people don't like the accent. I'm following through the whole course and its really helpful because of the backgroudn knowledge which I just don't get anywhere else, other people are just looking for quick answers and wouldn't appreciate the diversion into tokens. Just to clarify I think this guys amazing I feel as if I'm getting a complete understanding for the subject. =D
a ++ ++ + b. Value 'a' assigns 4 in the equation first, then increments. So, 4++ +3 is the completion of equation. Since 4 is a constant and a constant can't handle increment operator, this is an error.
Guy I never knew I could understand the topic of token generation and compiler design and how it interprets. I am really grateful to be in this century where everything is in the internet. Thank you
Your teaching is extremely good . Very deep explanation on concept I have got deep understanding on each and every concept. Thank you very much sir. Wish you were my teacher in college wouldn't have hated coding.🙏
ans:error because a+++++b can be generated as token as |a| |++| |++| |+| |b| now as it is the post increment first the equation will be evaluated then operand will be incremented, so a+b=7, and a=4 , two ++, ++ operators will be there, as increment acts on single operand another ++ can't be evaluated.so it gives error.
first of all you ar really great teacher ,I like the method you use to explain .regardless of it is my first time keeping following a lecturers online put I truly got a huge benefit out of your lecturers ,the answer is 8 because after token generation |a| |++| |+| |++| |b| so post increment we will use the value first the increment but in pre increment we must first increment the value .It goes like this a=4 b=3 so 4+4=8
Those are not the longest sequences of meaningful characters. What about |a| |++| |++| |+| |b| ? These are the longest sequences of meaningful characters, so we get an error "lvalue required as increment operand", because a++ ie a = a + 1 is not lvalue.
the answer is 8. because if we proper tokens between them like |a++| |+| |++b|. In que a=4 and b=3, |a++|=4 and |++b|=4 depending upon the given terms explaing in vedio on pre and post increment. so the answer is 4+4=8.
#include int main() { int a=4, b=3; printf("%d", a+++++b); return 0; } output : 8 solving: a++ + ++b hear a++ is post, or ++b is per and + is use of addition
It will show an error ,, but if we. Put the line. Like a++ + ++b then it will give the output 8 .. so after putting space at a &b we will get the output
[a] [++] [++] [+] [b] is error as no operand for 2nd [++] so is it possible for lexems to be like this? [a] [++] [+] [++] [b] because it has a option to either read it like [+] or [++]
Option (a) 7 Token will be generated as: [a] [++] [++] [+] [b] Which can be reduced as: a++ ++ + b {first assignment of variable then increment} 4 ++ + 3 [4++] + 3 {first assigment then increment 4 + 3 7 As there is use of post increment operators in all the stages hence the value of 4 is retained till the end. Please comment if I'm wrong.
You're totally wrong brother..there is no space provided in the code so token will be generated but the second increment operator will need a Lvalue..hence giving an error :)
sorry guys answer is d it divides the lexemes into a ++ ++ + b .and groups into a++ ++ +b .here lvalue is not there to store the value it gives error. So, answer is d.
Sir, you are great 😍.....i really understand the concepts deeply taught by you 😁. The answer will be for the last quest .|a| |++| |++| |+| |b| This will give error because it is unvalid expression 😁
the last question answer is an error because in token generation we get |a| |++| |++| |+| |b| in this case we are getting a++ ++ = (a+1)++ here (a+1) is a rvalue which is not allowed for increment so we will get an error.
Q3) L value required error Evaluation (a++)++ + b Once a++ is evaluated then it becomes 4++, since 4 is not a modifiable l value, compiler will throw and l value required error
@Poonam Rathore in my opinion it is the compiler error Bcoz when we are adding a+++b compiler simply generating token in that way a++ + b (I don't know how to put the value under the box in typing so I used space for clarification ) So, in given question we can think that the compiler should generate tokens in that way a++ ++ + b But what compiler do a++ but it is unable to add another post increment in it that's why it is showing error I think this might be helpful to you I am not 100% sure if someone clarify more betterly then leave a comment
@Poonam Rathore a+++++b in token is a ++ ++ + b. So it is same as writing [(a+1)++]+b..... And for the post increment operator lvalue is required but here a+1 is not a lvalue. So we get an error.
(a++) + (++b) => a + (b = b + 1, b) , a = a + 1 => a + (b = b + 1), a = a + 1 or something...but deepends on how the increment is implemented, as an r-val from an assignment expression or a CSV r-val from an assignment, object expression for which the latter would actually support them as l-vals then and cast to void if desired...

|a| |++| |++| |+| |b|
in this case we are getting
a++ ++ = (a+1)++
here (a+1) is a rvalue which is not allowed for increment so we will get an error.
You're the only one I saw who got the answer and explained it correctly.
the answer is option d because a+++++b [Error] lvalue required as increment operand
a++=(4 in expression)and(5 in increment) and again increment so ( a=5in expression) and(5+3)=8
wrong bro

Q3) L value required error
Evaluation (a++)++ + b
Once a++ is evaluated then it becomes 4++, since 4 is not a modifiable l value, compiler will throw and l value required error
Great Teacher!
it will produce error! thanks for this course, you're really great..
The answer was 8 for homework question sir
The answer is definitely d. Thank you so much for the great explanations
It runs the program when we use spaces i.e a++ + ++b and outputs 8 ... Otherwise gives errors.
Right bro
@Poonam Rathore in my opinion it is the compiler error
Bcoz when we are adding a+++b compiler simply generating token in that way a++ + b (I don't know how to put the value under the box in typing so I used space for clarification )
So, in given question we can think that the compiler should generate tokens in that way
a++ ++ + b
But what compiler do a++ but it is unable to add another post increment in it that's why it is showing error
I think this might be helpful to you
I am not 100% sure if someone clarify more betterly then leave a comment
@Poonam Rathore a+++++b in token is a ++ ++ + b. So it is same as writing [(a+1)++]+b..... And for the post increment operator lvalue is required but here a+1 is not a lvalue. So we get an error.
Very good and clear lecture on c programming i love this teachers learning techniques,i am a bca student 2024❤
ERROR: lvalue required as increment operand
(a++) + (++b) => a + (b = b + 1, b) , a = a + 1 => a + (b = b + 1), a = a + 1 or something...but deepends on how the increment is implemented, as an r-val from an assignment expression or a CSV r-val from an assignment, object expression for which the latter would actually support them as l-vals then and cast to void if desired...
