Hi,

So I've been staring at my code for a couple of hours, and I can't for the life of me figure out where I'm going wrong. I'm supposed to be making a program to determine if a 3x3 matrix is a Markov Matrix. Any help/suggestions are super appreciated. Thanks!

​

Here is my code:

​

#include <iostream>

using namespace std;

​

const int SIZE = 3;

​

bool isMarkovMatrix(const double m[][SIZE]);

​

int main()

{

double a\[SIZE\]\[SIZE\];

cout << "Enter a 3-by-3 matrix row by row: " << endl;

​

for (int i = 0; i < 3; i  )

{

    for (int j = 0; j < 3; j  )

    {

        cin >> a\[i\]\[j\];

    }

}

​

if (isMarkovMatrix(a))

{

    cout << "It is a Markov matrix." << endl;

}

​

else

{

    cout << "It is not a Markov matrix." << endl;

}

​

return 0;

}

​

bool isMarkovMatrix(const double m[][SIZE])

{

bool isMarkov = true;

​

for (int i = 0; i < SIZE; i  )

{

    int sum = 0;

    for (int j = 0; j < SIZE; j  )

    {

        if (m\[i\]\[j\] >= 0)

        {

sum = m[j][i];

        }

        else

        {

isMarkov = false;

        }

    }

    if (sum != 1)

    {

        isMarkov = false;

    }   

}

return isMarkov;

}
