Re: [Dev-C++] dynamic array

[Fabien V. <fv...@fr...>]

With you're writting your program in C you can use:

int (*buffer)[];

buffer=(int*)malloc(size_of_entry*sizeof(int));

Then you can use your variable "buffer" as you would do with any array.
When you have finished to use your buffer do

free(buffer);
