Hello everyone! It's me again.

I replaced malloc calls with calloc and I put sizeof(char*) for the memory allocation call for the rows of the 2D array. There are no runtime errors.

Thank you...

Unfortunately, no. Now I have a runtime error on the free() call at the last line of fillArray(). The change of char* to char for referenceArray has introducted a new problem in the fillArray()...

Ok, here is the complete code.


#include <stdio.h>
#include <stdlib.h>
#include <string.h>

//Variables globales.
int width;
int height;

I don't think that I'm freeing the 2D array twice, because it is filled first in the fillArray() function. The referenceArray pointer is cleaned first and points to the newReferenceArray pointer....

Hello, everyone!

I have a problem with memory free. Here is the necessary code to understand the problem:


void fillArray(char** referenceArray, FILE* grid)
{
//Chaîne qui va contenir une...

Google showed me this Web site in less than 1 second and it took that amount of time to see the content.

Use &type_of_gas instead of type_of_gas.

Without more code, I cannot help much further.
