Compile and run line.cpp. Try changing the coordinate system.

/* Program: line.cpp */

#include "ccc_win.h" int ccc_win_main()

{

Point p(1, 3);

Point q(4, 7);

Line s(p,q);

cwin << s ;

s.move(2,5);

cwin << s ; return 0;

}

Now input an integer value altitude and use a loop to write your own graphics program 'fall.cpp' that produces a graphic representation of falling object (e.g. circle). An object has initial downward velocity 0. Each second, it's velocity increases by 32 ft/sec. Plot the descent of the falling object. Note that terminal velocity is 174 ft/sec so the object's velocity cannot exceed that speed.

Now modify your program to read an integer variable secondstoopen to open a parachute after n seconds. Assume the velocity decreases by 100 ft/sec after the chute opens until the downward velocity hits 17 ft/sec.

Note that outside the bottom of the loop is the code for where the chutist has landed ... put a message there.
