segmentation fault for 2D arrays

Question

I want to define a 2D array of very big size. But it is giving me segmentation fault?

  #include 

  int main () {
       int i;
       int te         


        

Answer 1

You can allocate the whole table in only one array but you won't be able to access array data with indices using two square brackets:

int * temp = malloc(4000*5000*sizeof(int));

to access the element (i,j) where previously you wrote temp[i][j], now you should now compute the index the following way:

temp[i*5000+j];

and do not forget to free the memory allocated for your table afterward:

free(temp);
