n this lab exercise, you are required to write a $C++$ program to add two $4**5$ matrices and then output the res

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 $1$: input$1.$txt

Please enter the name of the file containing data for Array $2$: input$2.$txt

The sum is:

$23456$

$3,4,5,6,7$

$56789$

Further requirements:

Create three functions:

readArray with void return and one $2D$ array argument and one string argument

printArray with void return and one $2$D array argument

sumArray with void return and three $2$D array arguments

Separate your code into three files as described in the lab:

main.cpp

myFunction.cpp

myFunction. $h$

Remember, you will have to break the compiling into three steps now:

a$.g++-$c main.cpp

b$.g++-$ c myFunction. cpp

c$.$ g$++$ main.o myfunction. o $-$o main

The two input files are available by clicking: input$1.$txt and input$2.$txt
