C++ Data structure help!! Please read the requirments. Everyword counts. And if you can build it using Linux, it would be awesome!

please build cases to test the program and take in mind any error the program might face.

you can have a good idea about the homework from here

COSC2430 Hw1: Dense Matrix Multiplication 1. Introduction You will create a C++ program to multiple two matrices, the operation is the same as linear algebra. You can use any algorithm to finish matrix multiplication, provided results are correct. It is preferred that your algorithm can multiple matrices efficiently, avoiding unnecessary products or data movement in the memory hierarchy. Given two matrices A m x n and Bjx k, you will compute result matrix C AB. 2. Input and Output The inputs are two text files, each should have one matrix. The output is a single text file, with one matrix. File format: There will be ONE matrix row per line in the file for each input matrix. Each value should be a real number that may or may not have a decimal part (e.g. 1, 2.1, 3.1416). Values are separated by spaces. Besides digitals, other irrelevant characters will be given too, so your code should be able to report errors and output "error" (case sensitive) 3. Program and input specification The main C++ program will become the executable to be tested by the TAs. The
