For each of the following structure declarations, determine the offset of each field, the total size of the structure, and its alignment requirement for x86-64:

A. struct P1 { short i; int c; int *j; short *d; }; B. struct P2 { int i [2]; char c [8]; short s[4]; long *j; }; C. struct P3 { long w [2] ; int *c [2] }; D. struct P4 { char w [16]; char *c [2] }; E. struct P5 { struct P4 a [2]; struct P1 t };
