In this assignment you will be writing three functions.



First you will write an input function with two parameters that uses
call by reference to read in two real-values for acceleration and
distance.

Second you will write a computation function with two real-valued
parameters (acceleration and distance) to compute time based on
acceleration (a) and distance (s). time is the square root of two
times the distance over acceleration (square root of the quantity:
2*s/a). When 2*s/a is a negative number, this function should report
the time value as 0.

Lastly, you will write an output function (with three parameters) to
report the results.

A sample main function might look like this:

int main() {
    double a,s,t;
    get_acceleration_distance_input(a,s);
    t = compute_time_from_acceleration_distance(a,s);
    output_acceleration_distance_time(a,s,t);
}
