If anyone can solve these two questions for me i would really appreciate it.

if month < 3 then

2- Unions:
You are required to create a union containing the various integer and float types and an array of unsigned chars.
The size of the array of chars should be the number of bytes used for storage of the largest variable type
Assign values to the various members of the union and then display the values of the bytes used for storage.

union AllTypes
{
  signed short    ssData;
  unsigned short  usData;
  signed long     slData;
  unsigned long   ulData;

  unsigned char   ucData[8];

  one function for 2 bytes (short), and one to swap 4 bytes (long)*/
