If you can do both please in C++ coding.

3. Better Point in Rectangle Perhaps using 4 points to represent a rectangle is a bit too much. Come up with a better representation for a rectangle. What we mean by better is that it uses fewer values. Write a new program called point_in_rect2.cpp, that uses your new representation, and still solves the same problem. 4. Angles Between Lines Staying on the Cartesian plane, write a C++ program that will take in 2 line segments and output the angle between them. If the two line segments have gradients mi, and m2, then: m2 - mi tano = 1 + mm2
