you dont need to cast malloc in c

i hope you talk about this in every single thing in c , for example : malloc function wha does it do , how it allocate , you talk about static variablies , Visualizing Static Variables are they reserved in heap or stack , why they don't popout after use like just normal variables , Because we know , first in last out so after we print them they should popout , when they popout etc... i hope you do this in future and thanks again for the informations here

This is really good. Is this 3b1b's anim library?

Super useful thanks buddy 😊😊

One of the best videos I’ve seen in a long time, and I’m an EE student, so that tells you a lot 😂❤

You shouldn't cast malloc, realloc, etc., to a pointer. You lose type information. MISRA C guidelines warns against this. The compiler will automatically handle the cast for you. Ex: int *a = malloc(sizeof(int));

Frankly the best way to become malloc pro is to avoid it, and use an arena/pool + VirtualAlloc/mmap (if you need dynamic memory) instead. It's still good to understand them, but keep in mind they kinda suck...

Bro what software do you use make the animations

The following code snippets have <stidio.h> and <stdlib.h> included Malloc() Code: int main() { int *array; int num_elements, i; int sum = 0; printf("Enter Number of Elements: "); scanf("%d", &num_elements); array = (int *)malloc(num_elements * sizeof(int)); if (array == NULL) { printf("Memory Allocation Failed"); return 1; } printf("Enter %d integers: ", num_elements); for (i = 0; i < num_elements; i++) { printf("Element %d: ", i + 1); scanf("%d", &array[i]); } for (i = 0; i < num_elements; i++) { sum += array[i]; } printf("Sum of elements: %d ", sum); free(array); return 0; } Calloc() Code: #define SIZE 3 void printBoard(int **board) { for (int i = 0; i < SIZE; i++) { for (int j = 0; j < SIZE; j++) { printf("%d ", board[i][j]); } printf(" "); } } int main() { int **board; board = (int **)calloc(SIZE, sizeof(int *)); for (int i = 0; i < SIZE; i++) { board[i] = (int *)calloc(SIZE, sizeof(int)); if (board[i] == NULL) { printf("Memory allocation failed! "); // Free previously allocated memory if failure occurs for (int j = 0; j < i; j++) { free(board[j]); } free(board); return 1; } } board[1][2] = 1; printBoard(board); } Realloc() Code: int main() { int *array = NULL; int size = 2; int count = 0; int input; array = (int *)malloc(size * sizeof(int)); if (array == NULL) { printf("Memory Allocation Failed "); return 1; } printf("Enter ints: "); for(;;) { scanf("%d", &input); if (input == -1) break; if (count == size) { size *=3; int *new_buffer = realloc(array, size * sizeof(int)); if (new_buffer == NULL) { printf("Memory Allocation Failed "); free(array); return 1; } array = new_buffer; } array[count++] = input; } printf("Entered Numbers: "); for (int i = 0; i < count; i++) { printf("%d ", array[i]); } printf(" "); free(array); return 0; }

This video is so underrated

Insanely good examples and very easy to understand.

Nice!

Could you please provide the source code for the last example?

Omg what a Exaplantion bro thanks for this amazing content..

Thank you!! any chance you can share us the code like put in the description or comment sectionn?

although i knew what a pointer is i watched this. is short well made and to the point only thing i'd add is the output of the code shown rather than just explaining / reading it out.

helped me a lot buddy, thanks a bunch!!!

good.

Very well-made and clear video!

math can be so beautiful

If you know some basics of C the pace is OK. Otherwise you have to stop playing. As a refresher fine!

thanks very nice

Yeah in my 5th week of learning C in college. Fuck pointers XD

We much prefer the use of Laplace transforms…

Howdy, Brother! What resistor should I use if I have a yellow 10mm LED Emitting Diode (1.8-2.2V) powered by two AA Batteries? I will have an on/off switch in the loop. Will 47 ohms work? i tried 100 ohm resistor but the batteries were getting hot. I'm not even sure if I asked the question properly . Thanks for any assistance.
