C_133 Dynamic Memory Allocation using malloc() | C Language Tutorials

[@grow_free]

In static memory allocation you have a glass full of water and in dynamic memory allocation you have an empty glass and a jug and you can take as per your need.

Nice bro

[@mithileshbhujade1613]

Sahi hai !

[@Moon_lovee]

Thanks bhai

[@kaushikkumargupta4497]

Exactly 💯

[@godzilla4706]

How bro felt after giving this beautiful example 😃😀

[@OmarfarouqMadey]

1. Static Memory Allocation (Toy Shelves): Imagine you own a toy store, and you have a fixed set of shelves with five slots. Each slot can hold a different toy. You decide in advance which toys will go into each slot. Once the toys are placed, you cannot change the shelves' structure, and the toys in those slots are fixed. This is similar to static memory allocation. 2. Dynamic Memory Allocation (Toy Store with Adjustable Shelves): Now, imagine you own a toy store, but this time you have the ability to add or remove shelves as needed. You start with an empty store and add shelves to accommodate toys as customers come in. If a customer leaves, you can remove the shelf to free up space. This represents dynamic memory allocation.

Ma'am, your ways of explaining concepts are too good, I learnt C and C++ at least 2 decades ago. Wish we had someone like you to teach us, would have aced it for sure. Thank you so much for your support.

[@Saumya-bhkt]

Static Memory Allocation Imagine you're organizing a party and you know exactly how many guests are coming. Let's say 20 people will attend, so you prepare exactly 20 chairs before the party starts. This is "static allocation" because you've reserved a fixed number of chairs (memory) in advance, even if some guests don’t show up. Dynamic Memory Allocation Now, imagine you’re unsure how many guests will attend your party. You prepare only a few chairs initially, and as more guests arrive, you keep adding chairs to accommodate them. This is "dynamic allocation", where you adjust based on the actual need at runtime. In short: - "Static allocation" is like preparing a fixed number of chairs. - "Dynamic allocation" is like adjusting the number of chairs based on how many guests show up.

Ma'am I am from northeast! Currently doing my BSC in Cs ! Your videos make programming even more better and easier! ✌️❤️❤️❤️

[@AnuragRawat01]

Real life example:- Static memory allocation:- having wallet so that we can pay currency notes whenever we need , for that we need to keep as much money inside wallet as expected no matter it'll be used or not. Dynamic memory allocation :- rather than having a wallet to pay money, we can keep Google pay or Paytm on our mobile so that we can pay money as per the need there will be no tention to keep currency notes Hope u guys can relate with it😅😅

not that appropriate example according to me

[@lokesh6828]

@@AnuragRawat01 The real life example can be Static memory allocation : Having Rs 10000 from which you can purchase anything but you cannot resell it. dynamic memory allocation: having Rs 100000 from which you can rent anything around you and when to return the rented item, you will get full refund and you can use it again and again.

Perfectly explained everything, an absolute perfection you have in your videos mam.

I'm watching another C course besides Jenny, both are amazing, but everytime I get confused there I come here and find the information missing that I was asking for in the other course. Anyway, no course is able to cover every aspect of a subject, so they are complementary, and Jenny is always great on explaning, thank you so much!

[@charimuvilla8693]

Hi Jenny love your videos! I would be very interested in a video that further explains how this magic box called malloc works behind the scenes. How does it find memory to give you? How expensive is it to call it and what are some good practices? Does memory fragmentation affect it at all?

[@rohank009]

Madam please provide video lecture on dynamically allocated structure concept what ever you are teaching is very useful and informative thanks for the concern.

she was explaning the logic of Dynamic memory allocation and its importance of a their food Chappathi. if you request your friend to bring you chappathi delivered @ your home since you are not sure how much hunger you are in, your friend might possiblly bring more number of chappathi (for eg:) 5 but you may eat just 2 or 3 and rest is a waste which is a example of Static memory. Where as if you go to a canteen or a restraunt and get the food according to your need and there is no wastage which is the example of Dynamic memory.

Diff b/w SMA and DMA SMA:memory cannot be reallocated or allocated during the run time of a program2)there is no need to free the memory DMA:memory can be reallocated or allocated during the run time of a program2)there must be use of freealloc function in DMA.

Just a genuine question, do you take personal tutions of students, I do understand your course, but sometimes I've got program questions which are difficult to understand 😅

I have a question Why we didn't declared the malloc function as "void* malloc(size_t size);" The real life example can be Static memory allocation : Having Rs 10000 from which you can purchase anything but you cannot resell it. dynamic memory allocation: having Rs 100000 from which you can rent anything around you and when to return the rented item, you will get full refund and you can use it again and again.
