enum data type usally user defined.
for ex:
enum{sunday,monday,tuesday};
enum x;

Answer / deepak mundhada

enum is a user defined data type . we have to use enum
keyword to specify it.
eg. #include<iostream.h>
class A
{ public:
enum Colour
{ colour_green=0,
colour_peach=0,
colour_white =1,
colour_yellow =2
};
//we cannot have color_green 2 times here
/*enum Colour
{ colour_green=0,
colour_peach=0,
colour_white =1,
colour_yellow =2,
colour_green=3, };
*/
//We cannot have another variable of same type as in enum
Colour
//as below
//int colour_yellow;

//We cannot have colour_white as it already declared in
enum Color
/*enum MyColour
{
colour_red, colour_white };
*/
//We cannot have another Struct or Union of same type as
below
//in the same scope
/*struct Colour
{ int red;
int green; };
*/

void compare(Colour colour1, Colour colour2);
};
void A::compare(A::Colour colour1, A::Colour colour2)
{ if(colour1 == colour2)
{ cout<<"colour1 and colour2 are same\n"; }
}}
int main()
{ A a;
a.compare(A::colour_green,A::colour_peach);
return(0);
}
Output:./a.out
colour1 and colour2 are same

You have an int array with n elements and a structure with three int members. ie struct No { unsigned int no1; unsigned int no2; unsigned int no3; }; Point1.Lets say 1 byte in the array element is represented like this - 1st 3 bits from LSB is one number, next 2 bits are 2nd no and last 3 bits are 3rd no. Now write a function, struct No* ExtractNos(unsigned int *, int count) which extracts each byte from array and converts LSByte in the order mentioned in point1.and save it the structure no1, no2, no3. in the function struct No* ExtractNos(unsigned int *, int count), first parameter points to the base address of array and second parameter says the no of elements in the array. For example: if your array LSB is Hex F7 then result no1 = 7, no2 = 2, no3 = 7. In the same way convert all the elements from the array and save the result in array of structure.

2) Write a program that will help Air Traffic Control for an airport to view the sequence of flights ready for take-off. The airport can accommodate 10 flights waiting for take-off at any point in time. Each flight has a unique 3 digit numeric identifier. &#61550; Each time a flight takes-off, Air Traffic Control adds a flight to the waitlist. Each time a flight is added to the waitlist, the list of flights waiting to take-off must be displayed. &#61550; When a flight is cleared for take-off, Air Traffic Control removes the flight from the waitlist. Each time a flight takes-off, the list of flights waiting to take-off must be displayed. &#61550; Sequence of take-off is the sequence of addition to the waitlist
