Question

I was doing some C coding and after reading some C code I’ve noticed that there are code snippets like

char *foo = (char *)malloc(sizeof(char) * someDynamicAmount);

So I want to ask what’s more C-ish way to allocate memory for char array? Use sizeof(char) and supposedly future-proof the code against any standard changes or omit it and use the number directly?

Answer 1

The more Cish way would be

char* foo = malloc(someDynamicAmount * sizeof *foo);

referencing the variable and not the type so that the type isn’t needed.
And without casting the result of malloc (which is C++ish).
