A union will allocate only the space required by one element(the element that occupies the maximum size).Suppose you have a union consisting of 4 variables(of different data types),than the union will allocate space onlu to the variable that requires the maximum memory space. For example:

union shirt
{
char size;
int chest;
}mine;
The union variable 'mine' will be allocate only 4 bytes(the compiler knows,that tha character will require only one byte,while an integer needs 4 bytes.It allots 'mine' a total of only 4 bytes
