I am unsure on what im doing wrong.

[Haveed]

Im not sure on what I put inside my 3 files, Shapes.dat, Area.dat and Perimeter.dat. Am i only supposed to use 2 files? or 3 files.

Instructions:
The programming assignment for Chapter 8 is designed to challenge your
understanding of arrays, repetition, and selection. Your program should:
1. Introduce the program to the user.
2. Obtain 2 file names from the user. One contains the names of several
simple geometric shapes.
3. Read the shape name file into an array of shape names.
4. In the second file, each line contains two floating point numbers associated
with each shape (each line corresponds to the names in the other file): area
and perimeter. These numbers are to be read into a multidimensional
array.
5. Your program should create three different output files: Shapes.dat,
Areas.dat, and Perimeter.dat. The data in each of these output files should
be presented in a table of aligned columns. The first column is shape name,
the second is area and the third is perimeter.
a. Shapes.dat should contain the data sorted with shape names in
alphabetical order (the associated data should appear on the same
line as the shape name).
b. Areas.dat should contain the same data, but sorted from the smallest
area to the largest.
c. Perimeter.dat should contain the same data, but sorted from the
smallest perimeter to the largest.
Remember to arrange the data in the appropriate order.
