c++

please don't copy another solution , i want it simple.

Practice 1. Write a program that reads two vectors and calculate the angle in radius between these two vectors (Ref: slide 47). they Example: 4.5) 3.7) . =cos 1.079 radius -1-12+35 158241 23 = cos 0.472 =61.86 48.765 COS Note: - Use math library - Read the head file: math.h - acos(x): function returns the Inverse Cosine (cos-1) of the elements of x. Output: First Vector elements Second Vector elements the male in radits between the two vector 16: 1.07963 C\Users Othmani\Documents\Visual Studio 2010\Projects\labs\Debug\labs.exe enter the array's elements Number 2 enter the First Vector elements Element 1 -4 Element 2 enter the Second Vector elements Element i Element 2 the angle in raduis between the two vectors is: 1.07963
