Lab Exercise. -2-D Arrays in C++` In this lab exercise, you are required to write a C++ program to add two 4 * 5 matrices and then output the results to the screen. Prompt the user to enter the name of two files with matrices Compute the sum of the two matrices and output the results A sample run is as follows: Please enter the name of the file containing data for Array 1: input1.txt Please enter the name of the file containing data for Array 2: input2.txt The sum is: - 2 3 4 5 6 3 4 5 6 7 4 5 6 7 8 5 6 7 8 9 . Further requirements: o Create three functions: readArray printArray with void return and one 2D array argument with void return and three 2D array arguments with void return and one 2D array argument and one string argument sumArray o Separate your code into three files as described in the lab: H main.cpp myFunction.cpp myFunction.h o Remember, you will have to break the compiling into three steps now: a. g++ -c main.cpp b. g++ -c my Function.cpp C. g++ main.o my Function.o -o main o The two input files are available by clicking: input1.txt and input2.txt
