69 - DIFFERENCE BETWEEN STRUCTURE & UNION - C PROGRAMMING

Difference between union and structure is in memory allocated to the variable.
For structure variable the memory allocated is the sum of sizes of all the members of a structure.
For Union variable the memory allocated is the highest size of the member of a union.

[@irukoticherishma1751]

Excellent explaination sir ...👏👏

[@drnnarayana5027]

Explained it with a great conceptual clarity sir.

[@anatomic_anime]

Thankyou sir ❤

[@kalyanachakravarthi2736]

Sir in the example which you gave for unions, will the union can only save one element at a time or can it save both the elements?

[@vidyapaygude8650]

Thnks, so far clear and easiest explanation

[@girishkumar9550]

tell me in which type of condition where union can be use. and why use union. why not structure

[@sivaprasadchitikella5947]

Super sir nice Explanation

[@madhamanish8959]

Thank you so much sir .. Cleared my confusion

[@SatishNaidu_143]

Sir we want clarifies structure, function, pointer, files chapter some clarification in that programme not understand if you want to explain

[@bidyutkrdas54]

Sir,what happens if we declare the float first in union and then int ?will the output somehow change?

[@vimalareddy5957]

Sir for union the output will print only the higher value?

[@dharma3404]

Sir in the previous video about structures u said that if we give a tag name to the structure we have declare structure variable in the main function but in this program why u have declared before main function but u have given tag name student does it matter or not please explain sir?

[@iniyaviji2796]

Clear explaination thank u sir

[@siddhu-46]

Nice explanation 👌

[@srisaiadithiya1318]

Thank you very much sir

[@praneethReddyGangidi]

Sir if both data types have same size then how the memory is allocated and what will be the output

[@sundeepsaradhi]

hi Praneeth if both the members are of same data type like struct { int a; int b; }s1; Here S1 is structure variable with two members with integer data type so Memory allocated for S1 is 4 Bytes. union { int a; int b; }s1; Here S1 is union variable with two members with integer data type so Memory allocated for S1 is 2 Bytes and the same 2 Bytes will be shared by both the union members. Hope your doubt has been clarified.

[@ashutoshsahoo1870]

it will take one of them

[@naurinsultana1166]

You r the best sir

[@kp7677]

Very simple He made understand

[@abdulfareed2585]

Great explained 😍

[@anindasen3818]

very nicely explained.

[@anithat9275]

Sir I need the difference between static memory and dynamic allocation can you send the link

[@harshnarai8627]

Thanku sir very briefly explained

[@ANGamer990]

Thanks

[@dudekulachandbasha9959]

By u r lecturer I will get good marks sir conform pakka

[@kommirihemalatha2686]

Then what is the use of union sir

[@ashutoshsahoo1870]

sir, I'm geting worng out put #include union student{ int roll; float mark; }s1 = {10, 99.9}; main() { printf("Values of S1 : %d \t %f ", s1.roll, s1.mark); } output : Values of S1 : 10 0.000000

[@BasantGurukull]

whats the error ?

[@subratakundu8713]

&

[@jatrothgopal]

Good sir

[@tejeswarv450]

Awesome explanation

[@varevatalkies4853]

Sir, please upload videos on files, type definition ,dynamic memory location ,preprocessor directives,sir, please.....

Yes sir

[@m.vijayaraghavendra9364]

How to use unions to arrays

[@jibu9336]

super sir

[@Strafkolonie]

So are unions used to save memory ?

[@kalyanachakravarthi2736]

yes

[@poojithaganduri4093]

Tq

[@puneethhb7905]

Sir how to a declare function

[@base2base217]

In the union program I get as output the first member of the union variable s1, and not the highest is shared, i.e rno = 20 perc = 0.00000 May I have an answer?

[@chanakyabharadwaj1286]

its u.i not s use u.i for union u will get the answer

[@codingvibesofficial]

Same for me

[@Hmkm522]

sir about merge and quick sort pls explain sir

[@sundeepsaradhi]

HI manoj definitely i will upload them soon with in 2 or 3 days

[@harshith_takkala]

sir for float it is coming 0.0000 what should i do

[@dudekulachandbasha9959]

No douts sir very t q sir

[@faizanhabib4585]

Nice

[@Mysteryp7]

hi isnt int 4 byte?

[@silverwerewolf975]

yep

[@zoteasailofs1526]

Thankyouuu

[@k.s.saideepak5240]

Sir ,then how to print rno value in union ?

[@GodNinja.69]

Just dont print tha percentage

[@Hmkm522]

thank u sir

That was good u deserve a like and subscribe!!

[@palakurpushpa9241]

Tq sir

[@sarambakrishnancp9475]

Ok bie

[@manikantaswamysirivella7531]

Tell use of union

[@shantanunayek3072]

Sir suppose we have char and int datatypes under union... Now we store 10 into int and print%c, char... What output we will get? Does it gives 10?

[@surya_Narayana-bc2wd]

I requested sir

[@adss5095]

This is why i hate byjus 😁

[@sivakrishna4502]

super sir
