Consider the following C declaration and assume that the machine has 1-byte characters, 2-byte short, 4-byte integers, 4-byte single-precision floating point numbers, 4-byte pointers, 8-byte double- precision floating-point numbers, and the compiler does not reorder fields and leaves no memory gaps. You may consider all other data types as 8-byte. union UI ( int value; char code; double data; void pointer; }; union U2 ( float func; short small [2]; }; union U3 ( B; char text; long long number; }; union U4 ( char name [6]; unsigned int id; }; struct S ( int index; union Ui item; union U4 person; void next;
