1.)A union is a way of providing an alternate way of
describing the same memory area. In this way, you could
have a struct that contains a union, so that the "static",
or similar portion of the data is described first, and the
portion that changes is described by the union. The idea of
a union could be handled in a different way by having 2
different structs defined, and making a pointer to each
kind of struct. The pointer to struct "a" could be assigned
to the value of a buffer, and the pointer to struct "b"
could be assigned to the same buffer, but now a->somefield
and b->someotherfield are both located in the same buffer.
That is the idea behind a union. It gives different ways to
break down the same buffer area.

2.)The difference between structure and union in c are: 1.
union allocates the memory equal to the maximum memory
required by the member of the union but structure allocates
the memory equal to the total memory required by the
members. 2. In union, one block is used by all the member
of the union but in case of structure, each member have
their own memory space

3.)Detailed Example:
struct foo
{
char c;
long l;
char *p;
};

union bar
{
char c;
long l;
char *p;
};

A struct foo contains all of the elements c, l, and p. Each
element is
separate and distinct.

A union bar contains only one of the elements c, l, and p
at any given
time. Each element is stored in the same memory location
(well, they all
start at the same memory location), and you can only refer
to the element
which was last stored. (ie: after "barptr->c = 2;" you
cannot reference
any of the other elements, such as "barptr->p" without
invoking undefined
behavior.)

write a function to give demostrate the functionality of 3d in 1d. function prototye: change(int value,int indexX,int indexY,int indexZ, int [] 1dArray); value=what is the date; indexX=x-asix indexY=y-axis indexZ=z-axis and 1dArray=in which and where the value is stored??

I need your help, i need a Turbo C code for this problem.. hope u'll help me guys.? Your program will have a 3x3 array. The user will input the sum of each row and each column. Then the user will input 3 values and store them anywhere, or any location or index, temporarily in the array. Your program will supply the remaining six (6) values and determine the exact location of each value in the array. Example: Input: Sum of row 1: 6 Sum of row 2: 15 Sum of row 3: 24 Sum of column 1: 12 Sum of column 2: 15 Sum of column 3: 18 Value 1: 3 Value 2: 5 Value 3: 6 Output: Sum of Row 1 2 3 6 4 5 6 15 7 8 9 24 Sum of Column 12 15 18 Note: Your program will not necessary sort the walues in the array Thanks..
