Write a program to perform the following:
1. Open a file (input.dat) to read the elements of a 3 X 3 matrix and save them into a two-dimensional array,

2. Call a user-defined function to find the average of each row using pointer notations and print the result inside this function into another file (output.dat).

3. Call another user-defined function to print only the diagonal numbers and print the results on the monitor.
Maximum points will be given if you use pointer notation.
Input Matrix Average
1 4 7 = 4
2 5 8 = 5
3 0 4 = 2.33
The diagonal values are: 1 5 4

What specifically are you having trouble with?

how to begin this program, I'm a little behind in class and its heading toward the end of the semester soon.

[LB]

You begin the program by writing the hello-world program, but without the hello-world part.

i just need some help bro. would you mind making a sample program for me based of the instruction it would be greatly appreciated.

[LB]

#include <iostream>

int main()
{
    std::cout << "Hello, World!" << std::endl;
}

I would suggest making a Matrix class to store the matrices that you read in. Then write member functions in the class to solve problems 2 and 3.

The first thing you want to get working is being able to read correctly from the file into a Matrix object. I hope you know what the format of the file is, as that is necessary to get it to work. I assume it looks something like:

int int int
int int int
int int int

Write a function outside the class that takes a Matrix object as a parameter and read the values into the private attribute two-dimensional array as you read them from the file. Make a temporary input.dat to read in from. Since it is an assignment, I can't tell you exactly how to do that.

Use a different method to print out the values of the two dimensional array so you know you read in properly. From there you can start writing functions to perform 2 and 3.

This is just how I would go about solving it. Good luck!

thanks so much for all of you guys help its really appreciated I'm working on getting this program done its a bit tough I'm in my book 24/7.. again thanks if anyone has anymore help its VERY welcome
