May 09, 2022 · I have to say that printf("%d", ((int *) malloc(3*sizeof(int)))[1] = 33); is an extremely creative line of C code, although it's really terrible code :) This statement does the following: it calls malloc which allocates enough space for 3 integers (let's say 12 bytes). The address of the new memory location is then returned by that function.
