main()
{
int a,b,c;
printf("enter a,b values:");
scanf("%d%d",&a,&b);
c=((a)-(-b));
printf("sum of a,b is %d",c);

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
