What's the correct way to add 1 byte to a pointer in C/C++?

Question

I\'m using this code to move pointer by 1 byte now, but I\'m feeling something unclear..

int* a = (int*)malloc(sizeof(int));
void* b = ((char*)a)+1;   
         


        

Answer 1

((char*&)a)++;

Or:

a = (int*)((char*)a+1);

I hope you know exactly what you're doing. For one thing, you're ending up with - by definition - unaligned int pointer. Depending on architecture and OS, this might be trouble.
