Structure Padding in C

Question

If I have a structure definition in C of the following

typedef struct example 
{
  char c;
  int ii;
  int iii;
};

What should be the memory al

Answer 1

Under normal 32 bit it should take 12 bytes - the c field will be padded. This is architecture and compiler depended, however.

You can always use a pragma for the compiler to declare the alignment for the structure (and for some compilers, change the default alignment).
