Segmentation fault (Core dumped)

Question

I have a problem in C. My program generally works good but when I try to make an array with more than 10.000 elements it throw this error. What to do?

Answer 1

Lighton if you are getting a segmentation fault then it means that you are trying to access a memory location that is not accessible.
Edit: 10000*5000 = 50000000 elements and each occupy 4 bytes of memory so the memory occupied is 200000000 bytes. Do you understand how big is that?

Answer 2

Can you show us the code?

Answer 3

Ruchika Tripathi your post is irrelevant!

Answer 4

HonFu To be honest I do not know the answer to that but a 200 mb file sounds very big. In general our files are hardly few kilo bytes.
I do not exactly know that what part of RAM is allocated for a particular program but I hope to find the answer to that.

Answer 5

Kit D. Cat how does one check for the stack memory on their system? Also thank you for making things clear.

Answer 6

Avinesh, is there some way to know how large these arrays can be?
I mean, sure, what is it, 200 mb, is large, but shouldn't a regular pc be able to do it anyway?

Answer 7

Okay, 8mb is not a lot... So if OP reconfigured the code to using heap space, huge arrays like that would become possible?

Answer 8

Yes, wait a moment

Answer 10

It's a part of my school excercise.
Line 35 is accidentally there so it was not the problem.
Can you run it with 10000*5000 elements

Answer 11

Oh yes, so the problem is in the size of this array. There is no any syntax mistakes, right?

Answer 12

Remove line 35 and then input 2 array size values. It outputs m×n matrix.
But do not understand what you are trying to achieve.

Answer 13

Le problème est dans l'espace mémoire je pense.
