C_132 Introduction to Dynamic Memory Allocation in C | SMA vs DMA

[@bhaskarchakraborty8328]

Sma - complie time Dma - run time Dma - pointer required Sma - doest require any pointer Dma - memory can be freed Sma - wastage of memory

[@sarthaksavarn8913]

Sma :- permanent memory allocation throughout the program Dma :- we can change the size of memory during the program

[@ictfan-ly8gh]

Sma-- less efficient Dma-- more efficient Sma---program executes faster Dma--program executes less fast

[@TanujGutta-r3k]

​@@sarthaksavarn8913but memory is free after the completion of the program in sma

[@harshithchowdary5731]

Sma allocate the memory at compile time Dma allocates the memory in run time In sma we cannot change the size of the memory once we allocated But in dma we can change size the size of the memory

[@divyprakashpandey4458]

Notes for this session: - In SMA, the compiler is pre-defined for how much memory is to be allocated to a certain variable & these memory allocated at run-time CANNOT be modified during runtime - In DMA ,The compiler allocates memory as per programmer needs and this memory can be changed during the runtime of code - DMA is one of the application of Pointers - Always remember to free the memory from the pointer once, you're done! - Memory is dynamically allocated from the Heap

Key Differences: Static memory allocation occurs at compile time and has a fixed size and lifetime, while dynamic memory allocation occurs at runtime, with variable size and potentially longer lifetimes. Static memory allocation is often used for simple, fixed-size data structures and is managed automatically by the compiler. Dynamic memory allocation is used when data sizes are not known in advance and requires manual management. Static allocation is typically faster and more deterministic, while dynamic allocation provides greater flexibility. Dynamic allocation can lead to memory leaks or other runtime issues if memory is not deallocated properly. Static allocation avoids such issues. The choice between static and dynamic memory allocation depends on the specific requirements of the program and the need for flexibility, performance, and memory management control.

I am very glad you are back Jenny! Please whenever it is convenient for you, make videos about storage classes (auto, register, static, external storage classes) and command-line arguments, explaining the nuts and bolts of them as you do always. Thank you very much and again happy to see you back🙏

[@parisa9374]

More requests dear Jenny;) May you please make some videos on how you generally study and learn new concepts from CS and IT that you are this much comfortable and knowledgeable ( I know it is practice and experience but I would like to know your approach toward learning new concepts in CS/IT? How do you study and read the CS textbooks? What else that you are recommending? Thank you very much and keep up the great work! Take care 🙏

SMA DMA 1)At Compile time. 1) At run time. 2)memory is allocated form stack frame 2)memory is allocated form Heap(pool of free ( stack memory segment). memory block). 3)Fixed memory allocation (we cannot increase or 3)we can increase or decrease memory decrease memory size according to our pr. Req.) size according to our pr. Req. 4)we take var, ptr also. 4)here we req. ptr to access mem. From heap. 5)we free allocated mem. Afte exit the program. 5)in DMA:= we can use malloc(),calloc(),free(),realloc() to free memory and all. & we free memory block and t reusability) to use in many time in program and any whrere. (mem. Is reusabale).

[@EhabSmH0]

SMA: 1- You can not free the remaining memory, and the remaining will be a waste of memory. 2- Memory allocated from the stack part. 3- Pointers does not require. DMA: 1- You can free the remaining memory. (allocate and deallocate) 2- Memory allocated dynamically from the heap part. 3- Pointers are a must.

sma:-memory allocation at compile time i.e fixed memory memory stored in stack loss and wastage of memory cant be freed until end of the program dma:-memory aloocated at run time i.e variable memory we can change memory allocation according to our usage memory stored in heap no loss or wastage of memory can be freed anywhere btw the end of the program

Sma=in sma we can allocate the memory from stack Dma=in dma we can allocate the memory from heap Sma=memory can be allocated at compile time Dma=memory can be allocated at run time Sma=memory can be wastage Dma=memory can be reused

Thank you ma'am for well explanation.

[@tharunranjith720]

Mam I love the way you teach ❤❤❤

[@hariparuchuru3858]

Some of the difference between SMA & DMA STATIC MEMORY ALLOCATION: Memory allocated at compile time Memory is alloted from STACK Fixed memory Allocation( can't change at anytime once initialized) Memory wastage happens We take variables, pointers etc... DYNAMIC MEMORY ALLOCATION: Memory allocated at runtime. Memory is alloted from HEAP Memory is not fixed we can change according to our requirements Efficient usage of memory To perform DMA we need a POINTER and these memory should be FREED during the program so that it can be reused again.

[@rasithnovfal1920]

Assignment:The difference between sma and dma is in sma the mem is allocated in the stack but we cant free the memory during the runtime means we cant reuse then in dma the mem is allocated in the heep part and it also provides a way to free the memory which can be reused....🤪

[@calebmuchiri8162]

Hi Jenny,thank you for the videos they're very helpful,kindly go through the memory layout .

[@Strawberry12352]

Ma'am, you said after the execution the memory will be freed like that same block can be used in another program. But during execution, the memory is allocated for that particular variable so that memory is not available only during that program. so my question is whatever code we write that things don't take any space in memory once execution is done? (as you said they are freed in sma also)

Static memory location:- It is a process of allocating memory at run time of a program. Here memory sized is fixed and it can't be reused. Dynamic Memory Allocation:- Process of allocating and de allocating memory at run time of a program. Here , memory can be used again and again as it shows the property of reusability. 💯💥

[@debojitacharjee]

*BUT A PROGRAM IS COMPILED TO MACHINE LANGUAGE ONLY WITHOUT EXECUTION* - compiler only converts the code to machine language and stores in a file but doesn't execute the program, then how STATIC memory is allocated? STATIC memory will be allocated only if it's defined in the code whether to allocate STATIC or DYNAMIC memory. For example, if thr size of an array was defined by any integer value in the code then STATIC memory will be allocated during execution. But if any variable is used to get the size from user input or from any other processing then it will be DYNAMIC allocation.
