I see code like ...

I see code like
char *p = malloc(strlen(s) + 1);
strcpy(p, s);

Shouldn't that be malloc((strlen(s) + 1) * sizeof(char))?

It's never necessary to multiply by sizeof(char), since sizeof(char) is, by definition, exactly 1. (On the other hand, multiplying by sizeof(char) doesn't hurt, and in some circumstances may help by introducing a size_t into the expression;

I im trying to declare a pointer and allocate some space for it
I'm trying to declare a pointer and allocate some space for it, but it's not working. What's wrong with this code? char *p; *p = malloc(10); The pointer you declared is p, not *p. When you're manipulating the pointer itself (for example when you're setting it to make it point somewhere), you just us... 2016-06-10, 2636👍, 0💬

How can I dynamically allocate arrays?
