scanf("%d %d %d",&a,&b,&c);
if(a=0&&b=0)
printf("no solution");
else
if(a=0)
{
root=-c/b;
printf("root=%d",root);
}
else
if[(b*b-4*a*c)>0]
{
x1=[-b+sqrt (b*b-4*a*c)]/(2*a);
x2=[-b-sqrt (b*b-4*a*c)]/(2*a);
printf("the roots are x1=%f,x2=%f",x1,x2);

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
