Syntax of first line in Jenny's lecture: "In the series of programming in C we had discussed (most recent topic name), Thank you very much mam, even village people can understand your quality lectures which helps us to become a digital citizen. # Jenny's lectures for life.
Yeah so what's the problem in it if we put && operation and it will also reduce the time complexity
If && condition not true then simply print "not equal" .
In the series of learning programming in c..... 😊
11:39 it will return a negative value since the ASCII value of 'e' is smaller than that of 'i'.
I'm transitioning to IT and I love your lessons, one of the few out there that I can really understand everything. Thank you for your great work, ma'am!

Was 🥰🥰💕
First time Hindi sune mam
Love from West Bengal, India ❣️❣️❣️
20:20 Using the condition with &&, if length of S1 < length of S2 and the first characters of S2 = S1, then the strings will be considered to be the same. Ex. S1 = "Me" and S2 = "Meat". The reason is that as soon as the Null character of S1 is encountered, the program will skip the loop, so the comparison with the remaining characters of S2 will not occur and the flag will never be changed to 1.
Thank you so much

#include

int main()
{
int value;
char s1[] = "Hello";
char s2[] = "Hey";
value = strcmp(s1,s2);
if (value == 0)
{
printf("Same");
}
else
{
printf("Not same");
}
printf("

return 0;
}
output
Not same
-1
Thanks 🎉
Great Indian ppl have really conquered the programming world. respect!!
shut up
20:28 No if we put && operator then it will never give correct output as the function of && operator is that if both the Condition is satisfied then only it will enter to its block but if in the second string if we found the null character in 2nd block only then it will not execute that block n so we can't use && operator :)
Thank you ma'am for this amazing explanation....got the concept of comparing two strings very nicely..✌🏻✌🏻
ma'am i had some doubt on string comparison. but after saw this video , i easily understand this topic. thank you ma'am.
I love your lesson. It is so helpful. I am subscribed to your channel now. Thank you
Mam aaap bhot achha pdhati ho
12:00 for without strcmp
maam i loveeee your teaching so much pls pls plssssss do DAA and OS after completeing C
Madam you’re rocking in internet
You cannot use && operator .
You can examine it by taking
string 1 = welcome
String 2 = we.
👍
Using && He and Hello will return same string value bcoz after 2 it will not run and flag cannot have the value of 1 since at last same value
I think it gives 1 if the first non-matching letter in string is higher in first string, and -1 if the first non matching letter is smaller (obv in ASCII value)
madam please start python playlist from basic to advanced🤗🤗🤗
Yes mam
Yes ma'am
On comparing string("Hello") and string("Hi") using strcmp() ,it will return negative value.
2d array string with logical memory representation video mam !!
11:40 it will return a negative value. ASCII value of 'e' is smaller than ASCII value of 'i'.
Thanks a lot mam you have cleared my doubts regarding this string program.
Thank you mam ...I am your first viewer
You are to intelligent and very helpful to us
1st view and 1st like, mam, good teaching
Congratulations u won 🏅
You are best mam😘😘😘😘
//comparing two strings

Ma'am please start python series basic to advance.
Yes ma'am please 🙏
And ur explanation is superb and interesting . I just want to say thank u very much 👍
Hi Mam, i like your videos , and your way of teaching is so good. Regarding this program i'm using code blocks and Dev C++ IDE. for learning c. if i enter a String1 ANANTH and String2 Ananth, i'm getting the both the strings are equal.
Conceptual study thanks maam
I am in love with your awesome explanation
Mam is it necessary to take flag variable?
Can we directly print ("not same"
); and the break;? Please reply I m get confused.
Then how will you check whether they both are same
I am not student of computer science... But i watch your teaching videos.... Mathematics ka student hu... C progam k liye dekta hu
Thank you so much mam❤️
Draw a flowchart to find the fibonacci series till term
*WHERE DO WE USE IT?* - you have shown how to compare strings using for loop but you did show with a program where we need to use the strcmp() and what's it's application in software development.
11:35 negative value ,since ascii value of ''i'' is greater than that of ''e''
Ma'am, you missed strncmp concept.
Plz make a brief video on it.
Thnx For this mam🙂
char s1[]="Hello";
char s2[]="Hi";
it will give negative value (-4) because i comes after e , so i have greater sky value than e
Ma'am isma && operator hona chahiye kyuki when i=2 S2 will end no need to check S1 after this
Mujhe bhi yahi doubt aa rha tha but 25:31 p dekho ki agar flag ki value 1 ho tab not same kahega aur flag ki value 1 krne k liye loop k andar jana padega.
Mam plz add some hindi words in between please please please i regularly watch ur vedio but sometimes english makes problem to understand❤❤❤❤
ma'am actually here you said that without using string.h header file you have done but some of the compilers asking string.h header file like gdb online compiler
Mam what it will give +ve or -ve when we give input as strl and strm
Mam in this logic if the strings are : "hello" and " he" the code will return that the strings are same which is not true
1.you should put '\0' instead of "\0" (or) 2.use || instead of &&
@@bireswarsaha4881 that's what I meant.
First thing in strcmp function is ,,if length of both string is not same we can very well say ,,string is not identical in our own function case
by using logical and operater it will check both the conditions and as we can see that both the conditions are true so it will go further and if anyone condition is false then the program will be ended from the loop.
I cannot understand why if we use and operator this program will not give desired output.. pls can you tell me..
@@ParamitaDey-bi1mg Because to apply and operater both the conditions should be true then and then the program will be further executed
@@tirthtanna7771 See my question is if we use or operator then if one condition is true then it will go inside if loop . So if we take He instead of Hi in second string then second string will have string index 2(including null character )and first string index will have 5(including null character) so here for loop will go on till i=5 although there is no need to check up to 5 because at i=2 only we get null character in string 2. But as we are using or operator so if one condition is true (means S1[2]!='\0') then only it will go to if loop but it is not checking whether S2[2] is null character or not
So is not and operator better than or oparetor?
I don't know whether I can clear my doubt to you or not..
If you don't understand my question then pls say (" no I did not understand the question") or else I will wait for your reply
@@ParamitaDey-bi1mg I have the same doubt too
@@queennath1895 Did you got the ans?
At 11:37
It gives negative value mam
Mam ye cource compete hone ke bad data structure ke program ki list bna dena
C language me
Mam, is this method of comparing 2 strings correct?
char S1[30], S2[30];
int i, j, l1, l2, count = 0;
printf("Enter 1st string: ");
gets(S1);
printf("Enter 2nd string: ");
gets(S2);
l1 = strlen(S1);
l2 = strlen(S2);
if(l1 != l2)
{
printf("The entered strings are unequal.");
return 0;
}
else
{
for(i=j=0; i
👍
First else ka close bracket second else ke statement ke baad close karein to sahi ho jayega
Wo mai header file mention nhi kiya hu yha pe to last wala curly brace uske liye hai 😅
maam is it nessessary to learn without strcmp() function??
if we use && opr in loop then it not give correct o/p , if both cond is true then only it enter into loop, so better use or opr in for loop.
Since i is greater than e so, it will return negative value
I'm getting error of "expected declaration or statement at the end of input"
if we use && operator then the face following difficulties
if we enter two string as
s1 = har
s2 = hari
we know that entered strings are not same but when we use and operator it will say as they are same
same in this case also
if
s1=hari
s2=har
it will only say not same when we enter two different character at start like
s1=welcome
s2=hari
then the output will be not same
so when we use && gate it in for loop it will not satisfy the condition
for(i=0;s1[i]!='\0' && s2[i]!='\0'; i++)
because in and gate even if one string reach null character firstly it will exit from the for loop then compiler wont check the remaining string which we had entered, without checking remaining string it will give output, which might true are false, sometimes correct sometime the output shown is wrong.

MAAM CAN I WRITE THIS TYPE
right but in one statement u missed semi colon
Hllo mam I new to your channel
Can you please tell mee how to prepare for gate CSE branch
What sources and book we have to do
And how did you prepare
As I want to to start
And I am in 2nd sem of
CSE
14:14 yes maam samjh rahe hai 🤓
if you enter string 1 as" jenny kh" and string 2 as "jenny khatri", out put says "same".
Same problem...this code has problem as when space is encountered flag is 0 so it is saying same
Sorry mam i made a mistake. Now i'm getting correct output
Cp ki namaskaram 🙏🙏🙏🙏
Thankyou ma'am
Thank you ma'am
Mam just had a doubt- in if loop when flag turn to 1 u used break, will that break the if loop only ? and not the for loop and anyways once the flag is up output will be same, i am bit confused, maybe what i can saying doesn't make any sense, idk
maybe their should be a condition outside the if loop that - if(flag==0) { break; }.
Waiting for java lecturers
put more videos on string like , reverse the word ,remove given char,replace given char
Maam please tell about arry, one dimentional array, two dimentionalarry multi dimentional erray and( arry string)
11.39 it will return a nagative value
11:36 negative value will be returned
Thank youuu
guys ..in 5:58 time ..mam use a word something like ESCAPE or ESCAY...can you plz tell me what mam said..what is the meaning of that word?? I can't understand the word prpperly...so I can't find it's meaning in dictionary or GOOGLE.. plz help me!!!
It is ASCII VALUE
@@aashishomre1624 thank you sir...got it later in string part....thank you
11:41
-ve
Can we compare more than two strings also , how to do that?
Hello
Hi
It will return -ve. Because i ascii is greater than e ascii
Samjh rahe ho 😂😂😂👏👏
It will return negative value
Maam i love you ❤
First viewer 😊
11.39 it will gives negative no.
Can you explain the code of permutations of string
is it necessary to write break for for loop
The condition will still be satisfy
what will happen if first character of both char arrays are same??
it will return negative value
Mam strchr( ) ka video nai h kya ?
Why mam is not taking the sije of string
Is he'\○' and he______'\○' are same
@11:35 -ve would be the answer
16:11 if there is a chance of shot circuit ????
ma'am i love you

Mam plz upload python tutorials 🙏🙏🙏
Mam how many lectures in this course
Why did she include the flag ?
hello
hi
it return -ve value i.e -4 because e small than i
Medam how to contract you . Please ineed your help
