I'm having a little bit of trouble regarding pointer casting in my program. Question is, how do I explain this to Clang? For some type X he has: So, when you cast a (void*) to (long), you are losing 32 bits of data in the conversion. Next, when doing pointer arithmetic, the addition operation will use the pointer's type to determine how many bytes to add to it when incrementing it. For a fairly recent compiler (that supports C99) you should not store or represent address as plain int value. The content you requested has been removed. So instead I modified the implementation of malloc to ensure it never allocates memory above the 4GB limit. In C (int)b is called an explicit conversion, i.e. rev2023.5.1.43405. As Ferruccio said, int must be replaced with intptr_t to make the program meaningful. Episode about a group who book passage on a space ship controlled by an AI, who turns out to be a human who can't leave his ship? INT36-C. Converting a pointer to integer or integer to pointer I agree passing a dynamically allocated pointer is fine (and I think the best way). I'm new to coding and am trying to implement a simple program on my own, that prompts the user the number of residents in an apt complex, the prompts the user to enter the names and apt numbers of each resident. pointer/reference to a derived class pointer/reference. Was Aristarchus the first to propose heliocentrism? Content Discovery initiative April 13 update: Related questions using a Review our technical responses for the 2023 Developer Survey. If you are going to pass the address you typically need to exert some more control over the lifetime of the object. Unless you have a valid address at that value, you are going to invoke undefined behaviour when try to use that pointer. Just because you're altering. Embedded hyperlinks in a thesis or research paper. My code is all over the place now but I appreciate you all helping me on my journey to mastery! Does a password policy with a restriction of repeated characters increase security? dynamic, and reinterpret casting. You can use any other pointer, or you can use (size_t), which is 64 bits.
