// SOME CRUCIAL COMMENTS ABOUT THE PROGRAM //
/* 1) m , n are the x coordinates of the object to be hit.
2) a,b are the y coordinates of the bullet.
3) g1,g2 are the x coordinates of the gun.
4) Initially the bit variable is set to 1.
after the gun shoots the bullet it is set to 0,
unless it reaches the top where it is again set to 1.
5) One can fire only one bullet at a time and has to wait
till the bullet reaches the top , for firing the next bullet. */
