Program to find the mid-point of a line

Given two coordinates of a line starting is (x1,y1) and ending is (x2,y2) find out the mid-point of a line.

Examples :

Input  : x1 = –1, y1 = 2, 
         x2 = 3, y2 = –6
Output : 1,–2

Input  : x1 = 6.4, y1 = 3 
         x2 = –10.7, y2 = 4
Output : –2.15, 3.5


The Midpoint Formula: The midpoint of two points, (x1, y2) and (x2, y2) is the point M found by the following formula: M = ((x1+x2)/2 , (y1+y2)/2)
