plz help me create this program

Write a program that will do the following:
1. Find the equivalent vector given the coordinates of two
points A(x1,y1) & B(x2,y2) (user entered coordinates)
2. Then using the vector components calculated in #1:
a) find & display the magnitude of the vector
b) find & display the normalized vector (unit vector)
c) find & display the slope of the vector
d) find & display the CCW normal of the vector
e) multiply the vector by a scalar (user entered)
and display the result
3. Extend the program to accept 4 points A,B,C,D
a) find the dot product AB dot CD
b) find the angle (in radians) between the vectors
