80%的学校还在给新生上C语言，是它们OUT了吗？大家好，最近有小伙伴在后台问我，大一新生学校在教C语言，是不是已经过时了？第一门语言应该学什么比较好？大学期间什么课程对于毕业之后的从业帮助比较大呢？今天这篇文章就和大家简单聊聊这个问题。本人是高中的时候学习编程的，那时候我们学的是Pascal。大家没听说过是很正常的，这是一门非常古老的语言。这门语言古老到什么程度呢？古老到它的IDE都是蓝屏的，看起来就像是死机了一样。大概长这样，当时我们在机房里写代码的时候，一片蓝光，跟进了鬼片现场似的。当时学Pascal也是浅尝辄止，只是学了一些基础阅读详情

题目：
Description
Given two rectangles and the coordinates of two points on the diagonals of each rectangle,you have to calculate the area of the intersected part of two rectangles. its sides are parallel to OX and OY .
Input
Input The first line of input is 8 positive numbers which indicate the coordinates of four points that must be on each diagonal.The 8 numbers are x1,y1,x2,y2,x3,y3,x4,y4.That means the two points on the first rectangle are(x1,y1),(x2,y2);the other two points on the second rectangle are (x3,y3),(x4,y4).
Output
Output For each case output the area of their intersected part in a single line.accurate up to 2 decimal places.
Sample Input
1.00 1.00 3.00 3.00 2.00 2.00 4.00 4.00
5.00 5.00 13.00 13.00 4.00 4.00 12.50 12.50
Sample Output
1.00
56.25
