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.  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.  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.  Sequence of take-off is the sequence of addition to the waitlist
