 Arrays help us to store and work with groups of data of the same type. The data is stored in consecutive memory spaces which can be accessed by using the name of the array and indexes or subscripts that indicate the position where the data is stored. Repetition structures provide us a simple way of accessing the data within an array.

 ###Orthodromic Distance
 
 
-To calculate the distance between two points in the Euclidean plane, you trace the straight line segment that joins the points and compute its length using the distance formula you studied in your Pre-Calculus course. To calculate the distance between two points in the surface of a sphere you don't use the straight line segment that joins them, you use the shortest distance between these points measured over the sphere. This distance is called the *orthodromic distance*. To calculate the orthodromic distance between two points in the earth globe, the latitude and longitude coordinates are used.

-C++ provides functions to read and write data to/from files.  In this laboratory experience you will be using one of the most rudimentary file input/output schemes provided in C++ to read/write from **text** files. Text files consist exclusively of ASCII characters which represent data in any of the primitive types provided by C++. Typically, the values are separated by spaces. For instance lets asumme that the file `nameAge.txt` contains some data about names and ages.

     6. `double cycleDistance(GISPOI A[], int size, int P[])`: Given an array of cities `A`, the size of the array, and an array `P` with a permutation of the integers in `[0, size-1]`, computes and returns the distance to travel the cycle of cities `A[P[0]]` $$\rightarrow$$ `A[P[1]]` $$\rightarrow \cdots \rightarrow$$ `A[P[size-1]]`. Remember that the distance you will calculate is the *orthodromic* distance.
