Difference between Malloc and Calloc function MALLOC CALLOC -Accept one argument only -Accept two argument -The allocated memory would be initialized With garbage value -The allocated memory would be initialized with 0. -Allocate single block of memory - Allocate multiple block of memory
Assignment one: #include #include int main (void) { int n,i,j,*ptr1; float num,*ptr2; printf(" Enter number of blocks: "); scanf("%d",&n); ptr1=(int *)calloc(n,sizeof(int)); if(ptr1==NULL) { printf("Cannot allocate memory "); exit(1); } printf("Enter values for calloc: "); for(i=0;i
This session's notes - Calloc() fxn - Calloc stands for Contiguous Allocation - Built-in function in stdlib.h - Its Function→Used to dynamically allocate multiple blocks of memory & each block is of same size - General Syntax↓ - void* calloc(size_t no._of_blocks , size_t*size_of_each_block); - Malloc VS Calloc - In Calloc the blocks are initialized with 0 & in Malloc it is initialized with Garbage Value - In Malloc a Single block of memory is allotted, In Calloc for same memory smaller memory blocks are allotted [yes, it confuses me too

Thank you first of all for all you have been doing, you have made c programming easy to grasp. I have a question please, some c programmers have raised the argument of typecasting the return value of malloc. They say it is not really right can you please shed more light on that because from my little understanding of C I actually agree with your method of Typecasting.
static means that the variable (even local) remains for the lifetime of the program and is not destroyed. Its accessibility is limited to the scope where it is defined (like function or file), but its value is not reinitialized during any access after the first access since the variable remains preserved throughout the code lifetime. If you initialize a local variable x in a function as static int x=0, and then increment it by 1 in each call of this function, then your outputs after five function calls will be 1,2,3,4,5. This is because static x retains its value from the last function call and is not reinitialized to 0, since x is not destroyed at the end of every function call. If, however, you declare x as an auto variable by simply doing int x=0, and call the function five times, then your output will be 1,1,1,1,1. This is because the auto variable will be reinitialized to 0 in each function call, as it will have been destroyed at the end of the previous function call. So, static preserves the variable even after your function and its local auto variables have been popped out of stack since static variables are not stored on stack, and therefore remain till the end of the program, thereby retaining their value. So, they behave like global variables but with their accessibility limited to the function in which they are defined. You can expand this understanding to multiple files in a program too. It is good to define variables as static locally to limit their accessibility to the function or file of interest, instead of declaring them as global. Static will preserve the variable values the same way as global, but limit the variable accessibility, which is good!
Mam I'm from Pakistan and I'm in 1st semester watching your lectures but it is in c language while we are learning c++ so getting some difficulty to understand. Would you please make some lectures on object oriented programming in c++ because we are to Confused in it
while i code assignment which was given by mam there is some error while executing it can anybody post that assignment code which was given by mam pls,,
Please tell the syllabus for gate exam mam now I am studying 1st year and I don't know what are the syllabus please help me mam I am from poor family I need to crack gate
in alloc also im getting 0 value im not getting garbage value in malloc #include #include // malloc is stands for memory allocation int main(){ int n,*p,i; printf("Enter the no u want to insert "); scanf("%d",&n); p=(int *)malloc(n*sizeof(int)); // printf("Enter the values "); // for(i=0;i

- Calloc() fxn
- Calloc stands for Contiguous Allocation
- Built-in function in stdlib.h
- Its Function→Used to dynamically allocate multiple blocks of memory & each block is of same size
- General Syntax↓
- void* calloc(size_t no._of_blocks , size_t*size_of_each_block);
- Malloc VS Calloc
- In Calloc the blocks are initialized with 0 & in Malloc it is initialized with Garbage Value
- In Malloc a Single block of memory is allotted, In Calloc for same memory smaller memory blocks are allotted [yes, it confuses me too

I love your teaching skill ma'am
mam.....you are so special....
thank you for being on RUclips for us.........😇😇😇
So lovely mam i watching your videos since one year i cleared 3rd year help the ur video❤
Gajab padhate ho mam 😍😍🥰 really very nice .
Mam could you please upload a video on malloc( ) with structures
Thanku mam
Please start python also...
Please mam
Ur teaching way is awesome
Please 🙏
The way you talk mam...❤️ It's just too much flashy

First view mam😍♥️
lots of thanks and appreciation for the beautiful content just like your beautiful heart
mam why we use calloc ??
what is need of calloc ??
why we need multiple block of memory 😐🤔🤔
THANKS 👍👍
Inhi topic malloc calloc k liye to c dekhna chalu kiya aur 1 mahine se last topic khatm kar k baitha hu aur aj jak ispe video aya
Continue mam never stop
Mam can you teach us competetive programing please
Thank you so much mam🙏🤗..
Beautiful
Lecture
Mam if possible make a separate video on STATIC variable ,,, because it is very confusing
static means that the variable (even local) remains for the lifetime of the program and is not destroyed. Its accessibility is limited to the scope where it is defined (like function or file), but its value is not reinitialized during any access after the first access since the variable remains preserved throughout the code lifetime.
If you initialize a local variable x in a function as static int x=0, and then increment it by 1 in each call of this function, then your outputs after five function calls will be 1,2,3,4,5. This is because static x retains its value from the last function call and is not reinitialized to 0, since x is not destroyed at the end of every function call. If, however, you declare x as an auto variable by simply doing int x=0, and call the function five times, then your output will be 1,1,1,1,1. This is because the auto variable will be reinitialized to 0 in each function call, as it will have been destroyed at the end of the previous function call.
So, static preserves the variable even after your function and its local auto variables have been popped out of stack since static variables are not stored on stack, and therefore remain till the end of the program, thereby retaining their value. So, they behave like global variables but with their accessibility limited to the function in which they are defined. You can expand this understanding to multiple files in a program too. It is good to define variables as static locally to limit their accessibility to the function or file of interest, instead of declaring them as global. Static will preserve the variable values the same way as global, but limit the variable accessibility, which is good!

Very nice 🙂
Thank you
wow in the black cloths you look so pretty
Mam ap vs code ka konsa verson use karti ho
Thanku very much mam
thanks a lot
Can you please say why we don't use calloc fuction while dynamically allocating memory for structures
In malloc memory is allocated to single block whereas in calloc multiple blocks are allocated with same memory
Hii ma'am
Data structure and algorithm series is completed or some videos are coming.......
Assignment Question -
#include
#include
void main()
{
int *ptr,n,i;
printf("
How many values for calloc:");
scanf("%d",&n);
ptr = (int*) calloc(n,sizeof(int));
for(i=0;i
Madam Jenny is Ada Lovelace 2 🥰
Thank you mam
amazing
Nice mam
Mam but we can do this like
Scanf("%d",&n);
a[n];
//instead of malloc mam
Please tell the syllabus for gate exam mam now I am studying 1st year and I don't know what are the syllabus please help me mam I am from poor family I need to crack gate
Why not coming the garbage value and zero value mam?
😊😊
Mam. Pls upload a topic regarding operator overloading in c++
i getting 0 for malloc function also. it is not generating and random garbage values
C language me abhi kitana baki hai ?
I love you

");

Mam please start java or c++with c
Mam how many lectures left
Mam...you are so #beautiful ..

Mam can you right and show me imp points
Why calloc intialized with ZERO& where malloc as GARBAGE???
Mam Yogi Ji Jeet Gye
Looks like they ran out of names when it came to naming calloc...

We can't use Integer pointer to store address of floating value.
