C Programming Tutorial - 47 - The Heap

[ramiropinkfloid]

I'm at the University and I even don't understeand anything at programming class, but your tutorials are freaking awesome man, keep it flyyying

[sherlockstark]

you don't sleep, do you ? 4:49 AM... Well, i only want to say you are awesome Thanks bucky.

[Matrixrms]

4:51 AM!!! thank you for really nice tutorials!

[saras]

Woww....I had such a hard time to understand what malloc I can't believe it was such an easy concept! Thanks a lot! you are really changing my view of programming! I really appreciate it!
btw, you always say that you are not a good father or a teacher, but I think you are good!

[petarpartaloski]

These tutorials, WOW, I can seriously learn 100% from these tutorials :O

[DoseOver]

that chapter is extremely useful but may be you should add the concept "DYNAMIC MEMORY ALLOCATION" to the name of the video perhaps? so that people can find the video and learn it from you directly? your choice of course :):) Thank you!

Bro men, you're the best. learned so much from you today than i have in 14 weeks from my Comp sci professor

[PostMeridianLyf]

You deserve a standing ovation for this

[amitagnani]

Do not cast the result of malloc in C:

[tikytak]

but doesn't that mean that now you need to know the amount of intergers required? and if so dont you still have the same problem you had at the beginning ? how many intergers -> how much memory?

[SenorQuichotte]

why are you using int instead of uint? these values never go negative. there are no negative addresses in the register.

i donot get the problem here to use heap her e in my code i ask the user the size of my array and it accept it and by the way i assume in original c will allote data in the free space memory so what really important about the heap ???
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
int main()
{
int x, i;
scanf("%d", &x);
int y[x];
for (i=0;i<x;++i)
{
y[i]=rand()%x+1;
printf("%d\n", y[i]);
}

return 0;
}

Pro tip: ctrl + shift + esc
Happy uninterrupted recording!

Can u guys explain what does (int *) in the 8th line for??

[danielanderson]

he is a great programmer and teacher, he would be cooler if he used the bloodshed compiler :-)

[aandrese]

I'm pretty sure each process has its own heap

[mikebarbosa]

So this isn't programming related, but does anyone know how to get those memory gauge and such he has on the top right?

[makodad]

sizeof is a keyword, not a function. You can drop the parenthesis.

[SteepVisions]

why not just int *points = malloc(sizeof(int)*5); ?

[kongyihfann]

what happen if an exception is thrown before the free()? Will the dynamically allocated memory still be freed? Or...exception/error that closes the program is not available in C?
