Help with C++ -- max. value

hello everyone...


i am beginner in C++ and i need your help to determine the maximum value of results((how can i determine the maximum value of Y and print it with its corresponding values?))

......here is the program (sample run)

Calculating a Trajectory Followed by a Projectile

Enter initial velocity [m/s]: 100
Enter initial angle [degree]: 60

Position and velocity
t x y vx vy
0.00 0.00 0.00 50.00 86.60
1.00 50.00 81.70 50.00 76.79
2.00 100.00 153.59 50.00 66.98

7.00 350.00 365.87 50.00 17.93
8.00 400.00 378.90 50.00 8.12
9.00 450.00 382.12 50.00 -1.69
10.00 500.00 375.53 50.00 -11.50
APEX:
t_max x_max y_max vx_max vy_max
9.00 450.00 382.12 50.00 -1.69

You can enlist the values of Y and sort them.There are several sorting algorithms available.

Keep track of position of max element in the original list and obtain values corresponding to that index numbers for other fields.
